(Since I’ve never really written many of my Kaito’s headcanons here (specifically for Kai, not just over the series and character in general)… A few notes. Since they’re the type of things that vary from Kaito to Kaito.

Mine is panromantic demisexual. Tends to be friendly and will flirt (more as Kid than Kaito) with anyone he likes, but he’s more ‘I’ll tease you but let’s cuddle’ if it goes beyond general niceties than ‘I want to have sex’. Or anything sexual. However, if he does get into more of a romantic relationship with someone where sex is involved, he can and will lean more in teasing about that and overall not minding anything and wanting it with that one particular person at times. (Cuddles still required.)

– On that note, he will melt if given back rubs. He gives them himself, to his other selves and people he’s close to that might need the relaxing, but also because he thinks it feels great himself.

He makes sure to get enough sleep, aside from a little lost when planning for heists, though he may take a nap before them if he feels he needs to. Kaito’s stayed up all night after a heist before because of police measures, and Hakuba got some evidence that led to him when he did three heists in a row and started getting a little sloppy in what he did. And both of those happened before the whole Pandora thing came out, he doesn’t want to be impaired in the slightest in case he’s met with guns on a heist. He’d rather stay alert and awake, thank you.

He will always have a scar on his right shoulder from the fight with the robot (even if the manga doesn’t seem to give him one…), and he has a few side injuries from guns, though not too scarred beyond those. Enough to where it’s odd, since any normal kid shouldn’t have multiple gun wounds, but not enough to where it’s completely noticeable. (Might also have a scar where the bullet skimmed his arm from the Red Tear, since it could have been deep enough and he couldn’t get to it immediately afterward.)

His phobia does make him uncomfortable around fish, but he can handle watching them, to an extent. Can ‘handle’ being near them. He just doesn’t want to touch the things, and will freak out if he does. So long as it gets off, it’s more limited to a funny reaction and ‘keep it away from me’… But if contact is kept, or he feels surrounded by them without an escape, he’ll probably start panicking. (Happened to my Kai only once so far, in Skype RP, when someone (ignorant of the phobia) pushed him facefirst into a small pond that had fish that were being fed. Was not good.)

Kid is a persona of both strength, slightly on the reckless side, in ways he can’t show as Kaito. Also defensive, though not in personality. As Kid, Kaito has a better poker face than usual, though it’s not completely perfect like his dad’s even now. (His dad’s being a confident smile in all situations, at most the only change being a disapproving frown.) Even as Kid, he’s far more expressive than the previous, though can reign in more behind the monocle, or even just the persona of the thief, and act with more confidence than he can normally. So he can go into a ‘Kid mode’ when at times. And reckless in that he can openly taunt authority and danger, as well as try more, than he can as a normal high school teen.

My Kaito is for more open to chatting with random people than is canon Kaito, since canon Kaito really isn’t that social. Though, for my take, it’s more because not much draws canon Kaito’s attention like rp scenarios are designed to do. He did take note of an old man doing magic, and the kids playing around as heros (and one familiar thief), so it’s not as though he’s not interested at all in interactions, it’s just that he normally has no reason to. …Though even then, my Kaito still leans more friendly than canon probably would.

And my Kaito’s relationship with Chikage and Jii is one where they’re more assistants. Jii especially, nothing like the anime where the man seems to do the recon and planning, my Kaito does that on his own. He just might get Jii when he needs a ride or the extra person to pull it off, and Jii does tend to remain on standby if plans need adjusting at the heist. His mom is still his mom, though of course he didn’t have the same connection to her as with his dad, though they both still care about each other. My general Chikage is looking into gems internationally to help out, and keeps in contact from time to time, though mostly with Jii because Kaito’s active and busy with school and heists. I personally think she’s moved on from Toichi’s death long ago, of course not forgetting him or anything, but healthy moving past it, and is mostly cheerful and seems laid back about things to try and help Kaito through, since he clearly hasn’t moved on. (And sure, general series headcanon, she did pull something similar to when Yukiko and Yuusaku disguised as enemies to get Conan to consider to stop looking into the organisation. Still not sure if she disguised herself or if Corbeau was a friend of hers helping out, but the bet on who would quit stealing was to get Kaito to stop his dangerous night life, without being obvious about it. In a way what pride he had would have made him accept the terms, even if he wouldn’t have been happy with himself. And maybe angry enough to challenge Corbeau again if he had lost at that time.)

In general, he will actually act in that he just considers Conan a kid way too smart for his age. Usually changes very soon depending on how often the other muns take movies into canon and interact with him in return. (Hehe, I don’t think many noticed that in the slightest. Mostly because it does quickly go to ‘I know you know’, and will stay like that the remainder of interactions. V: ) In essence with that, though, my Kaito is more based around the manga, and to an extent, the specials. So he does not live next door to Aoko, he technically doesn’t know Shinichi=Conan in all cases, and Blue Birthday happened after a lot had already occurred. He also can and does steal more than just gems, though usually for different reasons, and gems are still the most common thing he’s after now. But he will not hesitate to point out gems aren’t the only thing he’s stolen, he’s not tied down to the excuses the anime shoved in to explain why he stole a painting, a crown, a vanity box, and tried stealing a statue, none of which originally had gems. He as a muse just adapts to routes other people turn towards.

All the chocolate and cuddles. Yes, that is all for now.)
