now, never ;  a reverie endeavour — . ☆

Rated 21+ for occasional sex, violence, and dark themes. An indie OC ask / RP blog by @idolkilling. Lethargic and loreless. FUBM free; viewer discretion is advised.

𝐁𝐀𝐒𝐈𝐂𝐒

Please have some indication of your age (21+) visible before interacting.

Transgressive themes may be explored on this blog. Excessively graphic content will be tagged, CWed, and placed under a read-more, but anything “standard” to horror media or black comedy—sex, violence, morbid humour—will stay uncensored. Naturally, I do not condone crime or taboo IRL.

I respond to asks and threads sporadically, and may break from SNS for months at a time. This is a casual, no-commitment blog, so adjust your expectations with that in mind! 🙇 Conversely, feel free to reply to anything as late as you’d like; I can’t judge and will be happy to see an update ^^

𝐑𝐔𝐋𝐄𝐒

Do not write my character’s dialogue or actions for me. If you need to know what Xero would say or do for an RP response or blog cameo, just DM! If you really want it to be a surprise, you can ask @mihlen instead.

Keep Xero’s narrative principles in mind when interacting. As the author, there are some dynamics or scenarios I’d rather avoid to stay true to the concept of their character.

Keep interactions focused on the muse and blog’s story. If you’d like to talk about other things, go to @idolkilling (for OCs) or @killshopdeluxe (for everything else)!

You may reply IC to any of Xero’s IC posts, as well as use them to start RP threads without pre-discussion. Unless we share a setting, these interactions will be considered crack without a set timeline or story, and may not have bearing on Xero’s other relationships. If you’d like to set up an “official” or serious scene in a particular AU, DM me!

Unless we’ve already interacted ICly before, please ask before pinging Xero with an RP starter on your own blog. Starters sent via inbox don’t require previous discussion, though; just specify which AU you’d like to play in, or I’ll default to unspecified.

When RPing with this blog, please use the read-more function to cut your responses after the first paragraph / image to conserve vertical space.

I RP via prose, script, art, or a combination thereof. I don’t care if RP partners match my format—please engage however is fun for you!—and I may not match format unless specifically requested. I’m comfortable with 1×1s or groups of up to six (6) people with turn order hashed out OOC.

I can RP NSFW—explicit sex, violence, and other things not appropriate for polite company—and I’m fine with threads taking that direction naturally (without prior discussion). That said, I prefer to play these scenes “lighter” or more comedic, and as such, this is not the best blog for hardcore angst, whump, or intense steamy smut LOL 😅

𝐈𝐍𝐓𝐄𝐑𝐀𝐂𝐓𝐈𝐎𝐍𝐒 & 𝐒𝐇𝐈𝐏𝐏𝐈𝐍𝐆

Xero is a multiship muse geared towards casual dynamics—shipping OCs for fun without any plan to make them “canon.”

Xero is naturally flirtatious and thrives in “charged” interactions. This is does not necessarily indicate attraction—they’re just Like That—but if you prefer strictly platonic scenes, you may want to steer clear.

If you see your muse developing romantic, sexual, or otherwise intense feelings for Xero, feel free to pursue them—you don’t have to ask me first! Likewise, your OCs can make any sorts of advances towards them (even uncouth ones).

I cannot guarantee reciprocity. Xero is aroace-spec and their approach to relationships is as amorphous as they are. They are exceedingly picky, so whether or not they develop attachments to other characters depends on how things play out in RP.

If the chemistry is there, I’m amenable to making a ship exclusive in a particular AU, but I will not monoship Xero across all universes or specify a “main” partner on the blog. That said, my activity is erratic, so if you’d like the pairing or polycule to be active on SNS, I’d reconsider ^_T

𝐌𝐈𝐒𝐂𝐄𝐋𝐋𝐀𝐍𝐄𝐎𝐔𝐒

If you’d like to RP or talk OCs at length beyond Tumblr, I’m available on Discord. If we’ve interacted a few times already, feel free to DM for my username!

Thanks for reading this far! If you’d like to play IC, please comment below (with anything you’d like)—I’m more inclined to interact with muns whom I know read the pinned post, so you’ll get priority (♡˙³˙)

Bartender, thoughts on fellow staff? What about you, Cleaner? Friends, rivals, nuisances?

𝐎𝐎𝐂 ⸺ Finally got to these Qs!! I wanted to take the opportunity to practise sequential work, ahaha/// Thank you to @mihlen and @ramsauced for letting me borrow Guan-Ying, Caelan, Meiri, and Benny as cameos! As for Jude and Aaron—hopefully we can get some interactions with them and the Ouroboros going soon :3c

NOTE: If you’d like to reblog / comment, please check out the post about this comic on my main blog! I’d just like to keep the notes in one place, ahaha/// }}

Excuse me!

You're staff on this ship, yes? Sorry to bother you while cleaning, but you really remind me of two friends of mine, so would it be okay if I took a picture with you? I promise I won't publish it anywhere, but of course I'd understand if it made you uncomfortable regardless, so I wanted to ask first.

Setting: Anchors Aweigh! Where: Ship hallways, somewhere in the vicinity of the Observation Lounge When: Day 121, 7:30AM Who: Lavender Hillingdon, The Cleaner (Artem Elegy)

The Cleaner works from midnight to 8AM on average, so they’re just about finished with their shift when Lavender approaches. They raise their head from their task—polishing the tile floor of a high-traffic walkway—as she addresses them.

They loom over her as they turn, dwarfing Lavender by nearly a foot. Their eyes narrow into smiling crescents as their gaze meanders from the girl’s face to her phone and back again. Without speaking, they nod and gesture for her to come closer.

You've been gone for a while now.

When will you be home?

“But if you’re feeling lonely, I should be back next week.”

𝐎𝐎𝐂 ⸺ For context, this iteration of the Ouroboros came to Earth in a certain organisation’s attempt to study a “Void Mirror.” The organisation’s experiments went awry, and all personnel in the remote facility perished upon assimilating with the entity that came from beyond the mirror (the Ouroboros). While this entity was initially detained by for further research, it managed to escape and disappear by replacing the human Itsuki Amano and taking over his life.

After many years, the organisation tracked the Ouroboros down and gave it an ultimatum: It could either fake Itsuki Amano’s death and voluntarily submit to incarceration, or the organisation could force it to return by killing all of its friends. Naturally, it chose the path of least resistance. The above comic depicts the Ouroboros on probation; it is allowed to live amongst humans (posing as one in public), but must always be on call for when the organisation requires its abilities. Its current case features a series of murders that reek of a desperation that reminds it of Killer Girl. }}

Setting: Anchors Aweigh! Where: Nightclub, the bar When: Day 21, 10PM Who: Minkyu Han, The Bartender (Flamel Shi)

When you’re meeting a “stranger” for the “first time,” a hypothetical about date-rape sure is a way to break the ice. Starter posts here!

INT. NIGHTCLUB — BAR — NIGHT

THE BARTENDER: Well, that’s a way to break the ice. Good evening.

A lull; MINKYU HAN doesn’t reply. As THE BARTENDER fills the silence by tidying up their station, he studies them. They stay casual, mobile—hands fluid and steady: They’re used to roving eyes. They store a clean glass upside-down on a clean shelf, reorganise bottles of liquor, pour-spouts pristine.

Eventually, the blond’s smile is full of teeth—

MINKYU HAN: You don’t seem too concerned.

—yet THE BARTENDER only laughs, light and airy.

THE BARTENDER: Well, it’s not the weirdest opener I’ve heard. Cruise ship nightclub gets a lot of characters. ㅤ [ a smile, hands palm-down on the countertop ] Would you like me to get something started while we stew on your hypothetical?

[mihlen-rp]

Well, it’s not the weirdest opener I’ve heard. Cruise ship nightclub gets a lot of characters.

"<What>, what do you mean opener? I'm seriously concerned here!" Minkyu says, though his lack of tension seems at odds with his words. He laughs.

Would you like me to get something started while we stew on your hypothetical?

Why, yes he would! The question is what. Minkyu's drink preferences range from the mild to the fruity side, so often fulfilled by the simple delight of soju or the associated mixes. If he ordered a poktanju, would—he glances for a nametag—"Flamel" know what that is?

Not that a nightclub is any place for a bomb shot, or that a nightclub bar probably would have soju to begin with. Next time, next time…

Instead, Minkyu lifts a hand languidly, pointing towards a bottle of rum he recognizes behind the Bar. "Get me a mojito? Pineapple," he says, halfway asking. He's been leaning into the 'tropical vacation' vibe, lately.

[ouroboros-online]

“Opener? Conversation opener? I swear that’s a term, isn’t it?” the bartender echoes Minkyu’s laugh, light and airy. They shake their head and pluck a highball glass from the display. “One pineapple mojito, coming up.”

The bottle blond isn’t their only customer, but—while they flit around the bar for several moments, attending to other drunken clubgoers—they don’t leave him hanging for too long. They’re back by his side the moment the “I Kissed a Girl” remix blasting through the club stereo crossfades into a generic thrasher that has the walls rattling like a sledgehammer. As they gather the ingredients and begin to muddle the mint leaves, sugar, and pineapple into the bottom of the cup, the bartender speaks again.

“You have to be more specific,” they say, leaning towards the counter so Minkyu can hear their voice raised above the bassline. “How do I know someone’s spiking drinks?”

[ouroboros-online]

If you could only eat one thing for the rest of your life, what would it be?

“ ‘The living flesh of mortals’ is terribly undignified, but I suppose I am a cartoon villain in the most literal sense. Or… Cartoon morally grey side character? 笑”

Here’s to the 12th anniversary of my Ouroboros Calendars! 2025 had some highs and some lows, and overall I don’t believe it’s been my strongest year for OC art—I wish I did more coloured illustrations, for one thing! But I still dropped a couple bangers, and I finally rebooted Xero’s askblog, which I’d sorely missed ^^ Feel free to send your questions and characters their way, if you’re so inclined.

Come 2026, I want to see if I can commit to updating this blog at least once a week, whether I come bearing new art or spruced up works from my endless backlog. I also hope I can write more… Is one ficlet a month setting the bar too high? LOL

Happy New Year, everyone! Thanks for following me all this time ♥️

Here’s a link to last year’s calendar, which conveniently has every other calendar from 2013 to 2023 under the cut!

I tend to be too lazy to draw their 80s sci-fi-horror-esque transformation ablities but I want to show them off more ahaha. Simplifying the style is a good workaround…

Distracting

[ouroboros-online]

What is your type? Like what interests you in a partner?

“Do they have to be natural blondes? Ha, no. That makes the pool very small, doesn’t it?”

It’s not unusual for the live feed to glitch from time to time.

What's your favorite food? Something you can eat forever and not get tired of?

[mihlen-rp]

He had gone against his nature and, intentionally, not kept track of employee shifts on the cruise. It was a game of sorts, an invented frivolity to keep him amused three weeks in, where every foray into a venue was as exciting as the roll of a die to see when his whims and a certain schedule would align.

To rewind, briefly: Tonight, it's the club. After a half hour on the dance floor, Minkyu spots them behind the counter and smiles.

He spills into his seat, yes. He asks his question, yes:

"If someone was out there spiking drinks, what would you do?"

"Well, that’s a way to break the ice," the Bartender says with smile that only humors him, and there it is, there it is—that clueless act. Not a single crack in that mask, it's almost enough to give him chills.

He lets their greeting hang, his reply tempered by drink, and takes advantage of the lag to admire the Bartender's finely sculpted features: a dash of judgment, a lime garnish of disdain. When he cocks his head, the long tassel of his earring tickles his neck.

(And maybe, just maybe, his hair falls too artfully, silken even in the thick swamp of body heat and perfume.)

His mood seems giddy. His grin is unrestrained.

"You don't seem too concerned," he remarks.
