Point in Canon
Accelerator was originally taken from episode 20, after Yoshikawa had sent him in search of Last Order but before he had successfully located her. He has since been canon updated to after Amai Ao shoots him in the head. While he has recovered for the most part from his brain damage, it is mostly if not entirely due to a combination of some Micro denizens' abilities and advanced medical treatment in Micro that the Heaven Canceler could never offer him. His body back home is still in the same condition it would be. He merely has the new memories from back there, up through finding out the precise state of his condition. Accelerator has also experienced one awakening while in Micro, when he went into a homicidal trance, sprouted black mist-like wings and cried blood over believing Haru's kidnappers had killed her and hearing that they intended to fuck the (dead) body. He does not remember the wings part, so unless someone ever mentioned it to him, he is unaware of this.
Motivation
Before his canon update in April, Accelerator was heavily concentrated on finding a way out. Saving Last Order was important to him. Now that that has actually happened back home and she and the remaining clones are all safe, he has no particular motivation in Micro aside from learning how to live a normal life, surrounded by people who care about him and don't fear or judge him. It can be hard at times, because he is incredibly hard on himself and won't let him believe it is this easy, but no matter how stained with darkness he is and no matter how stubborn he remains about his ability to redeem himself, he will always, and does, ache for the light. He's been here so long that it's no longer a strange thing to have friends, although he won't let himself get used to being wanted or desired by others.
Sex Life
Accelerator usually goes looking for Yune on a weekly basis, at the very least. They have a relatively rowdy and ah... somewhat active sex life, given that Yune constantly enjoys variation and they have probably tried a lot of things. Sometimes against his consent, like the time she turned his dick into a popsicle because he wouldn't let her go down on him. He has dabbled with a few other people once each, and he's slept with his best friend Lucy (and once with Nyuu), but for the most part, he sleeps with Yune only. He doesn't consider her his lover - they're not "like that," nor does he want something committed and monogamous due to his trust issues - but he does consider Yune to literally be a part of him, and she is the first person he goes to when he feels the chip.
Except that time he was a chick for two and a half weeks. XD Accelerator's body issues due to his hormonal imbalance made him extremely uncomfortable over being stuck with a female body for so long. Yune only made fun of him (see the rooster post) and insisted on being the one putting it in, so he stayed away from her till he changed back. As a female, Accelerator prefers sex with girls, preferably either going down on them or wearing a strap-on, but he is not opposed to jerking guys off just for personal benefit and to piss off said guys.
Accelerator has shown to be predominantly heterosexual, though he has dabbled with men several times. He has no interest in ever being penetrated, however. Either Accelerator fucks you in the ass, or it's all handjobs. He's amazing at those, by the way. Accelerator's ability to change vectors allows him to increase arousal level and raise one's pulse with a single touch, and he takes full advantage of this when having sex with his partners. He's very good with his hands and mouth. (You can probably thank Yune for training him so well. :|b She was his first sexual experience and she made sure he soon knew what he was doing.)
Overall, Accelerator prefers to be dominant and is incredibly picky about partners due to dislike of casual touch and paranoia over his auto-deflective powers. Just because he has perfect control of them most of the time does not mean he always retains perfect control all the time, particularly when he's close to orgasm. His desire not to accidentally hurt a partner is partly why he refuses to let anyone use their cock or a strap-on on him, whether he's male or female. The idea of anyone sucking his cock is also... distasteful. His favorite things during sex are giving women oral, really rough penetrative sex, and toying with his partners to make them squirm. He is a sadist, and it shows.
Personal Finances, Living Arrangements, Work
Accelerator lives in the Cavallone Ranch with Miura Haru. They share an apartment on the fourth floor. In exchange for free room and board, Accelerator does odd jobs around the apartment complex. When it comes to money, either Haru gives him spending money, or there's his sex money. Probably 30-60µ a month from sex.
Accelerator has a dog and shares a cat with Haru, and Haru also has her own dog. Haru takes care of most of the cost as long as Accelerator takes care of them.
Meals come as part of the food and board benefits. Accelerator generally doesn't spend money on food unless it's something Haru didn't bother to get. He probably goes through lots and lots of canned coffee and energy drinks, however. This can suck up much of the money he has.
As for clothing, Accelerator rarely buys any. He sticks to his trademark black and white-designed shirt, and long pants. Shoes and underwear may be necessary now and then. Perhaps 20µ a month at most.
Character Relationships
Miura Haru [
so_tsunadere] - Haru-nee. Accelerator sees her as the older sister figure he never had. He is insanely protective of her and would kill if that's what it took. He'll never let her talk him into believing he's a good person, and insists he can't be completely trusted, but this is mainly him not allowing himself to get his hopes up, and him believing she's naturally way too trusting in the first place.
Lucy & Nyuu [
vectored_lilium] - Lucy is Accelerator's best friend, whom he occasionally 'dabbles' with. Similar backstories, similar powers... they're too similar to each other for them to ever be lovers, and Lucy already has one, but Accelerator cares about her a lot. He is jealous of some things he knows he has no right to be jealous of, like the fact that Lucy had friends back home or that she can hide her horns. Speaking of, he loves those. As for Nyuu, Accelerator tolerates her more than anything. Not in an act of fakeness, but let's just say that dealing with her can be... trying. He would go out of his way to protect her, so that makes up for finding her annoying at times. Besides, she's a part of Lucy, and in a way she reminds him of Last Order, only much more tolerable.
Yune [
alloutoforder] - The Goddess of Chaos, Yune helped him out the first time he got chipsick and went to the point of shocks. He's since grown very close to her. She accepts him for who he is, makes him feel like it's okay to be himself, and is very literally a part of him. There's also the fact that she looks albino. Yune can be downright annoying - she's gone up his nose, turned his dick into a popsicle, and been deliberately obtuse when fem!celerator asked her to give "him" his cock back - but she makes up for it by being unconditionally truthful and loving.
Helen [
makestrouble] - Helen is his not!friend. They don't know each other very well, but they occasionally share insulting banter with each other. Accelerator likes being a dick to her, but would never go as far as insinuating that she is a monster, due to his own monster issues. But he's not sure she understands that.
Ggio Vega [
ridethetiger] - Skullboy. Someone once mistook Accelerator for an arrancar due to his powers, but Accelerator was not impressed with the first arrancar he actually met. He enjoys being a dick to Ggio and has never bothered to learn his real name. Has now made it his goal in life to get the arrancat high on catnip and embarrass him now and then, after enjoying his first success of it.
Inoue Orihime [
holyfight] - That really nice, if somewhat bubbleheaded girl who used her powers to reverse the gunshot wound to his head. (Continuity is my bitch, okay? Okay.) He finds her naive, but her positive attitude is surprisingly not annoying like is his experience with others. Definitely a friend, but not a close one.
Greebo [
cat_harrassment] - That guy who's actually a cat. Accelerator slept with female Greebo once, but he's not big on touchy-feely partners, so he doesn't care to repeat it. Accelerator does occasionally stop and talk to the guy. He's curious what he looks like as a cat, but if he's seen feline Greebo he didn't recognize him.
Superbia Squalo [
jump_my_shark] - That annoying loud guy with the shark. Accelerator mainly tolerates him.
Belphegor [
princebatshit] - That stupid annoying prince. Accelerator barely gives him a thought except that he doesn't approve of Haru-nee sleeping with him. She should sleep with someone less dangerous.
Sonozaki Mion [
midsummersdemon] - Lucy's friend that he met on his own by chance, Mion has become a target for teasing. He likes to toy with her and make her squirm. Not that he is always successful. For some reason she's proud of having oversized tits. Accelerator has plans to team up with Lucy and double-team Mion.
Takahana Sumire [
antivirus_girl] - Lucy's lover. At first, that's all she was. They had a very awkward meeting, and Accelerator found it really hard to be cordial to her at first since there were things about Lucy's actions that he didn't understand or like. In time he's gotten to know her thanks to Nyuu's first appearance and the memory transfer plague. He also appreciated how understanding she was when he was turned into a female. He can see why Lucy likes her.
Giselle [
irl_fairytale] - That bubbly naive girl. She is fun to fluster and tease. He thinks she needs to have her bubble burst and finally learn what life is really like. It's not a completely innocent fairytale. People suck, some more than him.
Karisawa Erika [
dollaredup] - That weird girl who knew who he was, and stole his panties right off the female him during Truth or Dare.
Sumeragi Kururu [
onewithsound] - That ditzy blonde girl that lives on his floor. He doubts how much of a spine she claims to have, but doesn't dislike her. It just takes some getting used to someone so positive.
Kurosaki Ichigo [
suppressthedark] - That guy with the weird spiritual powers. Accelerator has never thought much of him, though at one point his powers did intrigue him.
Nakajima Subaru [
airgeargaigar] - That blue-haired girl who gave him Last Order pings when they first met. They don't know each other very well, but he's not a dick to her.
Martel Yggdrasill [
loving_goddess] - That goddess that Yune is close to. Accelerator's first encounter with her did not go well because he can be really abrasive, but since then they have been able to speak with some level of respect. When they do speak, it's usually about Yune.
Abilities
Accelerator's power is that of vector change. This expresses itself in numerous ways, but the primary methods are automatic and intentional. His default Redirection auto-deflects incoming vectors that are not on the current settings of his "harmless vector" filter. He allows sound and gravity most of the time, and obviously needs oxygen, but these are examples of the exceptions. Brain waves other than those of the MISAKA Sisters Network are always blocked, so telepaths cannot read his mind. As for intentional, he can manipulate the vectors of whatever he touches. This action inflicts his personal reality on the reality of everyone else, and lets him do things like block sound waves, create storms of wind and plasma from mere breezes, control the flow of liquids, redirect projectiles, deflect UV rays away from his skin, take control of the electrical signals in a person's brain, defy gravity, and further defy the laws of physics through what looks to others like superhuman speed and strength. Lifting a train car into the air? Easy. So is stopping a moving car and selectively crushing parts of it, or jumping ten meters into the air and rocketing from building ledge to building ledge with no fear of falling. All your vectors are belong to Accelerator.
This is something Accelerator relies on for everything, and he abuses it relentlessly. Without his power, he's little more than a weakling who doesn't know a lick about street fighting.
His
AIM field has the side effect of causing physical discomfort or ailments to magic users who use magic while in close enough proximity to him. Sorry about that, Shirou, except not? :> It is very heavily concentrated around his body, and he generates a lot of this psychic energy, enough so that it masks the scent of his body. People with heightened senses will get the feeling he's not all there because he smells so faint.
