Fool Night: A Title Dissection
This is neither an analysis nor a focus on a single theory. Think of this essay more as a guide. I'll be inspecting various ways the title can be interpreted linguistically and show how it currently does or can apply to the manga in the future. There is a vague spoiler from Chapter 77, but I generally write to an audience that has at least read the first two volumes.
Before I start, let me address why I'm basing my post on an English title for a Japanese manga. Fool Night isn't a unique target text translation but is rather the standard across all countries. Look at Volume 1's cover from the manga's original publisher. A closer inspection shows that the katakana sounds itself out to "Fūru Naito" once romanized in Hepburn, which then transliterates rather than translates back into Fool Night. Fool Night maintains its title for the French, German, Spanish, Castilian, and Italian target texts. Notice how the source text also has "Fool Night" on the top right of the cover, just in smaller print.
Furthermore, one part of a French interview by Arthur Bayon of the newspaper, Le Figaro, with the mangaka, Kasumi Yasuda, discusses the title’s origins as one thought through an English framework. I post the link to it below.
CHRONIQUE BD - Kasumi Yasuda mêle dystopie sociale, «body horror» et polar dans cette première série publiée en France, sélectionnée à Angou
Below is the relevant section of the interview:
Le choix de raconter la misère sociale et de mettre en scène un héros marginal s'inspire aussi du film Joker, de Todd Phillips, sorti en 2019. Le titre du manga pourrait être un clin d'œil («fool» signifie «bouffon» en anglais) mais l'auteur reste évasif à ce sujet: «J'avais d'abord pensé à l'appeler "Flower Night", mais je trouvais que ça manquait de sens, j'ai donc remplacé "Flower" par "Fool". Le terme correct serait plutôt "foolish", mais lorsque j'ai discuté de mon titre avec une de mes connaissances mangakas, elle était très enthousiasmée par cette formulation.» (The choice to tell the story of social misery and to feature a marginal hero is also inspired by Todd Phillips' film Joker, released in 2019. The manga's title could be a nod ("fool" means "jester" in English) but the author remains evasive on the subject: "I had initially thought of calling it "Flower Night", but I found that it lacked meaning, so I replaced "Flower" with "Fool". The correct term would rather be "foolish", but when I discussed my title with a mangaka acquaintance of mine, she was very enthusiastic about this formulation.") (Google Translate trans.; Bayon)
A standardized, English title across all target texts isn't especially rare (e.g., Shadows House, Chainsaw Man, Blue Lock, etc.). However, Fool Night stands out since most of these titles conform to this practice due to the title becoming a proper noun within each manga's respective world. Regardless of how much one wants to take Yasuda's intent under consideration, there's enough supporting evidence to justify an examination of the title using whatever English, linguistic techniques are available. With that out of the way, let's get to the point of this post. Due to the unfinished status of the series, I'm going to be pretty bare bones here.
1. The General Essence
This is the hardest point to define, but my impression is that casual, English readers assume the title resulted from an odd translation of some believed about (but as we now know, nonexistent) title of the source text. Consequently and ironically, English readers make a heuristic towards more intuitive titles like "Foolish Night", "A Night of Fools", "Fools’ Night". I have little to back this assumption, but I base this conclusion on my personal experience, along with consulting friends and the rather small Discord for the manga. Non-English readers should, at the very least, avoid the heuristic of people who are exclusively fluent in English. Unfortunately, I can only conjecture about how non-English readers and even multilingual people read into the title. All I know is that I have yet to see someone take a closer look at Fool Night's title.
Regardless of the assumption mentioned early in the previous paragraph being off base, how readers respond to and interpret that belief may best highlight a conventional, thematic overview of the series. In other words, the vibes of the title best capture the vibes of the series. I'll share my view on the conventional, thematic overview of the series, but while I doubt my overview will cause any problematic objections, how the noun “fool” fits in the context of that overview can lead to disagreement.
Toshiro’s impoverished background leading to his transfloration displays the consequences of capitalism by showing the economic system in a more advanced stage than our own. It has not been stated what caused and currently causes clouds to block the sun, but it’s easy to suspect that capitalism, a dominant force in climate change, bears the blame. In humanity’s attempt to recover a semblance of a more revered past during a time of collapse and crisis, those who have control maintains its economic system for means of exploitation: the poor are poorer and higher in percentage, its commodification pervades everywhere until one’s bodies become an economic need, and people will give up their life for a brief period of presumed happiness and security. As outsiders, the idea of transfloration seems grim and unwise to go through (outside of a few exceptions that Fool Night highlights). Yet, characters like Toshiro who consent to the procedure are, at my harshest, people who are hard to blame for their lapse in judgment when considering the overwhelming pressures of poverty; but, more likely, victims tricked into thinking their freedom of choice matters when they lack any better alternative.
The Oxford English Dictionary defines a fool (i.e., the most popular and appropriate use of fool within the context) as “a person lacking in intelligence or judgement, and related senses” (“Fool”, n1). The definition mentioned above fails to capture the connotations of the word, and, by extension, its overall character. That being said, the word is deceptively hard to distinguish its connotations and seems to have a degree of variability from person to person. For example, what differentiates the word from “moron”, “idiot”, “imbecile”, and the like?
The reason I bring the character of the definition into question is that the general, thematic overview fails to align with some popular ways in which the term is understood. Characters make fun of Toshiro for his weaknesses in certain mental abilities at times, but his decision to transflorate is, while tragic, one I struggle to say is unwise, idiotic, or even incorrect. In their world, many could find themselves in Toshiro’s situation regardless of one’s intelligence or wisdom. Additionally, while transfloration is considered the most direct and foolish decision one can make in Toshiro’s world, the series does not limit disadvantageous choices and conditions to whether one transflorates or not. Many are still endangered in ways unique to his world. If the absence of being wise or intelligent or the absence of wisdom or intelligence within the context of making a certain decision fails to describe what being a fool is in Fool Night, what does?
These past few years, I have considered the term as lacking a necessity to involve one’s level of cognition. To elaborate, I have considered acts of deception and trickery to work on the wise and intelligent. Furthermore, I have believed individuals can exercise wisdom and intelligence moments before and during the acts of trickery and deception. It was only in my research that I realized that this is perhaps a rather unique view of the word. I wouldn’t bring this up randomly. If one were to find this interpretation of the word acceptable, the “condition of being tricked or deceived” more accurately aligns with the manga’s themes. Engaging with the word in this way shifts focus from the mental capacities of the victims and onto the immorality of the manipulators, the means of deception, and the pain of victimhood. The idea of "a person lacking in intelligence or judgement, and related senses", due to its vagueness, does not enforce any idea of inherent intelligence, so my definition does not attempt to change the word into something unrecognizable. While readers may not intuitively grasp these conclusions, the manga clearly challenges perceptions of what it means to be a fool, inviting more nuanced judgments if given the time and effort.
The “night” needs little explaining—the world is surrounded by a perpetual night. A satisfying analysis of the symbolic character behind the world’s night lies outside the scope of the essay, but I can at least paint a general picture of how the night impacts the series. An unnamed teacher for Toshiro and Yomiko during their childhood days interprets night as acting “like a lid over everyone’s hearts”. How that imagery fits aesthetically within the rest of the series could inspire analysis elsewhere, but here, in its most basic terms, conveys that the night has blocked off empathy and passion. While the perpetual night worsens living conditions in tangible ways, it also reflects humanity’s response to those conditions: a pernicious gloom, an increased difficulty in seeing perspective outside of one’s own, and an absence of vitality.
Despite alluding to how this thematic overview fails to capture the full picture, it does capture the essential component. As I develop how the linguistic component changes the reading of the title, I’ll reaffirm that this broader lens remains largely uncompromised.
2. Etymology
Tracing the development of the word “fool” backwards shows that word derived from the French word “fol”, which stems (pun intended) from the Latin word “follis”—classical Latin has varying definitions, such as “bag”, “sack”, “money bag”, “purse”, “large inflated ball”, and “bellows”; yet, while the start of its usage has varying times in the early centuries, post-classical Latin also defines the word as an “arrogant person”, “foolish”, and a “person who speaks foolishly” (“Fool”, n1).
"Follis" also goes beyond those definitions above, for a type of coin in the Roman and Byzantine traditions was also called a follis. You could research more about the coin and the Latin word's PIE roots, but take it from me: credible, concrete findings aren't easy to come by.
Associating paper currency with air and adjacent terms isn’t unheard of, considering how paper is made of trees, but hopefully it’s apparent how unexpected foolishness is linguistically steeped in monetary roots. While perhaps a little too focused on the English translation for some, the manga adds on to a monetary, linguistic conflation and entanglement with the aforementioned schoolteacher. She advises Toshiro and Yomiko "to gather the richness in [their] hearts" to navigate successfully through their world in the sense that must find and exercise their passion and empathy. In the same chapter, Toshiro twists her words (subconsciously if not unintentionally) by saying transfloration will give him "ten million yen worth of richness in [his] heart", signaling how their world perceives a need of richness in a monetary sense.
Unfortunately, OED blocks access to the word “night” without a subscription, but the word does have a better range of sources. The meaning of “night” has remained stable through several derivations until the word reaches its Proto-Indo-European roots.
Let me interject by prefacing that I’m not arguing whether Yasuda intentionally utilizes Latin and PIE roots or not. Rather, etymological findings can uncover hidden truths and associations of certain words and concepts, extending as far as influencing stories as we know them, whether consciously or unconsciously. So, consider the next step in tracing back the origin of "night" and PIE word, “*nekwt”. The original root is thought most likely to be *nek-. Nineteenth-century British philologist Walter William Skeat argues this root meant “to perish”, “to disappear”, or ”to fail”, in reference to night being the time when light ceased and perished (Skeat). For a more contemporary example, Roland Pooth has asserted for the root term to be understood to mean “empty” or “naked”, with night being the point where the sky is naked and empty of light (Pooth).
Skeat’s view has more significance if one were to apply either term as a lens towards analyzing the manga, but I can see both having relevance. To reiterate, I’m not going to commit to analysis, but hopefully bringing this up serves as a good platform for it in the future.
3. Homophony
Homophony is what started this rabbit hole in my research. If anything, a more dedicated reader may notice the homophony at play in the title compared to other linguistic possibilities. One person in the aforementioned Discord also mentioned this to me. “Full” is a homophone for “fool”. While it hardly needs explaining, the world of the manga is full of night in the sense that it's all-encompassing and omnipresent. Now, there’s a slightly related definition of the word, one relating to one’s satisfaction with food and drink. Consider how the flora struggle with photosynthesis due to a lack of sunlight. Also consider humanity's struggle to acquire basic needs within the manga, especially in the context of the story’s focus on Yomiko’s joy in eating.
Homophony exists as a form of wordplay—an exercise that can function as an act of condensing information. In that sense, all uses of the phoneme don’t work as mutually exclusive but rather as interconnected information.
Of course, by strongly asserting the relevance of the homophony of “fool”, surely that applies to “night”... Wait a minute. If one has been following the story to its most recent chapter (Chapter 106 as of the time during the publication of this post), any speck of knightly imagery seems to be nonexistent. However, I’d like to bookmark this topic, for what I point to next could be grounds for speculation that knighthood in the manga could be a budding motif.
4. The Archetypal Fool
If you check the Le Figaro interview, Yasuda cites The Joker (2019) as a source of inspiration. I’m not going to do intertextual analysis, but it’s a good jumping-off point for a broader discussion about how Fool Night uses Toshiro as a symbol for the fools and jesters (terms used interchangeably in this context) who served under royal courts during the Middle Ages and Renaissance.
Textual support appears immediately with volume 1's cover. Toshiro uses his thumb to cause an abscission on and surrounding his mouth that resembles a smile akin to the face paint of jesters and clowns. Beyond the idea that people like Toshiro who transflorate could be fools in the broad sense, the image suggests that either people like Toshiro or Toshiro specifically displays traits of the fool archetype. I’m inclined to believe the designation is exclusive to Toshiro.
In the story, Toshiro exhibits qualities of a jester in a loose sense—he serves in a unique but dependent role within a facility of similar authority (i.e., Transflora Medical), where his lack of booksmarts makes him the butt of many jokes by those in a higher social position than him.
A great piece of supporting info would be Toshiro’s childhood hobby of playing the medolica and his initial aspirations of starring in a band, with music being one way jesters would entertain royal courts. He even brings his melodica to elementary school. Toshiro’s alignment with the fool archetype supports the application of homophony two-fold. Firstly, wordplay is primarily used to amuse others; thus, the title’s use of comedic homophony for this grim story now has a means of justification and relevance. Then, a major part of Toshiro’s character is his capacity to communicate with the spiraflora, so having a phonetic technique within the title contributes to the texture of the manga.
Yet, the irony of the archetype is that while they’re subject to others’ mocking, their simplicity belies their clever nature. Frederick Warde states that “to play such a part required more than ordinary wisdom” and that they must be someone of “great observation, judgment, and understanding; quick to take advantage of every occasion for the exercise of [their] wit” (Warde 2-3). While lacking in some areas, I have never clocked Toshiro as being anything less than average in overall intelligence, and he exercises a higher-than-average emotional intelligence within his world. To give an early example, Toshiro successfully plays mediator between a pianist, Sumi, and her abusive father, Shougo in a way those two are able find a sense of resolution while also being able using his personal experience to deny any form of justification for Shougo’s abuse.
I may have convinced you that Toshiro exemplifies the jester archetype, but I have yet to connect its relevance to how the story may use knighthood in the future. I believe he can exhibit signs of an archetypal fool transitioning (or hybridizing) into a knightly archetype, or, as you may be starting to see where I’m getting at, a “fool knight”. Despite setting itself in a post-apocalyptic Japan, the strong, textual support for the portrayal of the archetypal fool means that the use of knighthood in some capacity isn’t out of bounds in an aesthetic sense since the conception of the two archetypes occupies the same timeframe while serving under the same institute of power.
The imagery I’ve caught is small, but both Toshiro’s fully transflorated form—one resembling the shape of a cochlea (which, as the reader may have put together, the auditory nature of his power further supports the use of homophony in the title and his ties to jester imagery) and the mask Toshiro later uses for interrogating antagonists—can vaguely resemble Medieval helmets.
Without getting into the historical and literary weeds of the archetype, could a knight in this manga’s world represent a reclamation of love, empathy, and loyalty within a cold, untrusting, and callous world? Since I frame this thread as a guide, it would be better to let the reader decide if the knightly lens is an aspect worth keeping an eye out for and thinking over.
5. “Fool” as a Verb
My “knight” section could be too rambly and speculative for some, and unfortunately, this final way to see the title lacks tangibility and specificity. However, I won’t assert any developed theory and instead list possibilities that can be combined at will. Fool, as a verb, shares the same form with its nominal counterpart, and I suspect that the title sees this process as an opportunity to play with ambiguity.
If one were to see the first word of the title as a verb, one can see this lens as situated within the start of the plot, with humanity attempting to live in a way that makes it seem like they’re not living in perpetual night. However, considering how badly humanity is struggling at the start of the story, this could be a goal that Toshiro eventually reaches instead. Furthermore, what the subject is trying to fool can be metaphorical, as well. This act of deception could be placed at the beginning of the story or towards the end, similar to the more literally taken possibility.
While the story makes it easy to see how the underprivileged are fooled, viewing humanity’s persistence at survival as a kind of deception isn’t something directly acknowledged within the text. This perspective inspires a question I’m not sure if the text will engage with: what can humanity do at this point if not fool and deceive?
Final Thoughts
Regardless, the lenses to read Fool Night’s title—its general essence, homophony, archetypal application, and the ambiguity in the phrase’s construction—exist not to conflict with one another but to build up towards one, larger meaning. Certain components even manage to mutually reinforce each other. If the manga completes in the intermediate future, I would like to refashion this post into something more expansive, formal, and confident. For now, I feel that there’s enough stable, supporting evidence present in its ongoing publication to persuade one to read its title as one conceived with great care.
