The sunflower (himawari) primarily symbolizes admiration, loyalty, and "I only have eyes for you." These meanings stem directly from the flower's natural tendency to track and face the sun throughout the day.
Sunflowers are renowned for turning their heads to follow the sun through the sky - and I have no doubt that Ai can't help but watch as Conan solves case after case with brilliance!

Such strong connection that language is limited when trying to explain it— If that doesn't encompass the bond between Conan & Ai, then nothing can!
Alstroemeria, commonly called the Peruvian lily or lily of the Incas, is a genus of flowering plants native to South America. There are over a 100 species of Lily of the Incas, with varying colours and stripes, and these flowers can be found in almost all types of habitat.
In Hanakotoba (the Japanese language of flowers), the "Lily of the Incas" primarily symbolizes devotion, enduring friendship, and mutual support. Because this flower’s leaves grow upside down and twist out from the stem, it represents the unpredictable twists and turns of life. It is the perfect flower to tell someone, "I've got your back".
Sounds like a sturdy and versatile flower... Just as the bond between Conan and Ai seems to have many strands to it, and ever evolving.
What a great pick to start CoAi Week with - highlighting the undeniable connection of our ship!

Why is it that in the Detective Conan anime, when it comes to the episodes I've seen, Conan's thoughts are narrated by an older sounding actor compared to Conan's voice actor, but Haibara's thoughts aren't narrated by an older sounding actor and still sound like a child?
So! I have asked the people on our discord (link in our header) — and here's what we've got:
Some Question about which version you're watching? Most discord server members are used to a version where Conan's voice and Inner Narration are the same — including the Japanese Original.
Apparently the Catalan Dub changes both Conan and Ai's voices for the inner narration! And also has them using their adult voices with eachother?? With real old person sounding voices... Questions on the physics/biology of that. 🤔
Someone remembers when Haibara got the antidote, she still had the same voice when Shiho Miyano.
One interpretation is that women's voices don't change as much as men's over puberty, and since all voice actors are generally adults, with women voicing young boys, changing voice actor to indicate a change to an adult voice is only really needed for male characters?
Hi, I want to join the CoAi Week 2026. And it's my first time! I'd like to ask if tare there any minimum words or anything? Does it have to be a one shot only or multiple chapters? And if yes to multiple chapters, is it okay to not be able to finish everything??
There's no wordcount requirement - we simply ask that you do your best. 🫶
This is a week for fans of Conan/Shinichi x Ai/Shiho to share any type of fanwork in response to the prompts - and this includes one shots and multiple chapter fics!
You can scroll through the tags for previous years on our tumblr to see what people have previously made, but these have included: shorts, one shots, multi-parter fics, multiple chapter fics to be finished later on, meta analysis of the canonic materials - and that's just sticking to written contributions.
✍️The #fanfic tag should be very helpful to your search while on our blog.
We only request, if possible, that you have some reference to one of the prompts in the chapter you share under the #coaiweek2026 tag if it's a long multi-parter. (It's not rare for multi-parters to be shared with different prompts showing up in different chapters, not necessarily in prompt order either.)
The gardenia (specifically the kuchinashi flower) primarily symbolizes secret love, a silent crush, kind-hearted secrets and pure admiration. Its delicate fragrance and pure white blooms reflect inner purity and quiet affection. Gardenias are often associated with strength and grace, making them meaningful gifts for expressing unspoken emotions or deep respect. The flower's elegance underscores sincerity and emotional depth, ideal for conveying heartfelt feelings without words.
Conan and Ai, both keeping a cool head and their secrets as best they can, while still making a difference? Yes please.

The white chrysanthemum (kiku) is deeply tied to mourning, grief, and death. While the chrysanthemum overall represents longevity and rejuvenation—especially in imperial symbolism—the white variety carries somber connotations, contrasting with its use in weddings elsewhere. Despite this, white chrysanthemums also signify purity, sincerity, and truth, which can appear in celebratory contexts like weddings in other cultures. Their dual meanings highlight cultural nuance in floral symbolism.
Who can these two show their true feelings to, huh?
And what about Conan's constant quest for his Only One Truth?

The yellow camellia (kiiroi tsubaki) symbolizes longing and impatient waiting of unrequited affection. Unlike its white counterpart, which represents purity and respect, the yellow camellia carries a more bittersweet emotional tone. It is often associated with unspoken feelings or yearning, making it meaningful in poetic or heartfelt gestures. While Western interpretations may link the yellow camellia to excellence, the Japanese meaning emphasizes emotional depth and quiet desire.
Camellia plants are generally considered slow growing. This slow growth rate makes them well-suited for growing in pots or tubs, and they don't require frequent pruning.
I'm sure us CoAi/ShinShi fans are no strangers to the concept of a Slow Burn romance.

The zinnia generally represents loyalty, lasting affection, and endurance. Known in Japan as hyakunichisou (flower of 100 days), its meanings are deeply tied to its ability to continuously bloom through the harsh summer heat.
Cool anecdote: Zinnias were the first plants grown as part of a formal NASA experiment using the Veggie plant-growth system aboard the International Space Station!

Are gen works (that can interpreted both ways) allowed?
Hi there 👋
Absolutely! According to fandom wiki:
Shipping, derived from the word relationship, is the desire by fans for two or more people, either real-life celebrities or fictional characters, to be in a relationship, romantic or otherwise.
As long as it’s something that centers around Coai’s relationship and abide to our RULES , it’s all fair game!
The sunflower (himawari) primarily symbolizes admiration, loyalty, and "I only have eyes for you." These meanings stem directly from the flower's natural tendency to track and face the sun throughout the day.
Sunflowers are renowned for turning their heads to follow the sun through the sky - and I have no doubt that Ai can't help but watch as Conan solves case after case with brilliance!

file 1070 | when he promised that he'd always protect her and he meant it
lately i've been thinking about how natural conan/ shinichi and haibara/ shiho protect each other throughout the series:
conan saves haibara from the bus, he runs after her when he thought she left on a train but she didn't (hence the iconic "you'll protect me right?"), how he tranquilized her so she wouldn't follow him to meet vermouth, how he shouted her name and went after her whenever she ran away or when he was worried that she was hurt from the burning cabin.
how haibara outsmarts him, ruining his plot to outsmart vermouth (who turns out had a sniper behind her), because she doesn't want him to die in her place, being willing to give herself up if it means that he'll live.
how haibara holds his hand when she's scared, when she's leading him out of danger, how she holds onto his clothing because he makes her feel safe. how he holds her hand to lead her to safety and takes her hand so she can join the group/ watch the soccer game.
he gives her his glasses (his literal disguise) to put her at ease, he gives her his hat multiple times, he took off her shades at the soccer game, he saved haibara when she was cornered by pisco/gin/vodka.
how he worries about her enough to go to the professor's house to watch over her, how she worries about him enough to tell him that she's worried that he'll die if he keeps investigating the BO.
she gives him the antidote and saved him from tough situations multiple times, she goes to find him with the glasses saving him from the locker when he scared & hiding from gin, how she changed his status to dead so the organization won't go looking for him.
and this is just the manga/ anime, don't even get me started on the movies. like can we talk about how the people in charge of the movies definitely ship coai? there's always at least one iconic scene between them.
Here's my favorites in no particular order:
M5: he threw the helmet to protect her from the crystals, she went with him to solve the case
M6: they both talk trash about being in a room filled with nepo babies, she saves him from being crushed telling him to solve the case
Lupin III vs DC: haibara saves conan from being blasted by mine's rocket launcher
M16: haibara kicks the final shot conan needed to save their lives
M24: Haibara helping conan convince Ran that they need to stay because they're "just kids", how she knows conan was faking tripping to plant a bug on his target, how they both speak english fluently, how she helped him with the MRI incident, how she helped him on the train by getting the list, how she stopped Ran/ the stewardess from freaking out about the train by explaining the science behind it, how he signaled to her "thanks" with his badge and she waved back "no problem" and the stewardess shipping them from the background.
All of M26
M11: how he calls her his assistant, how she pulls out the blood bag so Mouri (by proxy Conan) could join in on the case
M15: how he covered her from the bullets "aren't you a little forward for a kid?", how he contacted her through the DB badge when the phone signal was cut off, how he told her that it was dangerous and they should go back but she say "no way" and made the ski board go faster, how he brought her with him to rescue the DB who were stranded on the side of the road.
M22: he went to her for help with a case, she listened to him when he was upset, they watch the news together
M19: how conan knew that haibara destroyed a nice jacket to save him
