Biological Gender: buddy they dont even know (rper refuses to tell us what it really is)
Full Personality: For the most part, their public personality is their real personality. Some of the stiffness and aloofness is a bit forced though, because they don't like expressing their emotions very much. They don't show it, but they're very bitter and cynical deep down, and are usually numb or callous in situations where most people would freak out. They have a morbid and odd sense of humor.
Full Backstory: When Akihisa was extremely young, their parents abandoned them and they ended up growing up in an orphanage. While there, they constantly kept track of time, waiting for the day their parents came back for them. They counted the days, weeks, months, even years. They never really interacted with the other kids in the orphanage, mostly watched them and observed their routines and personalities. They also tried to learn a bit of psychology and similar things to try and find a reason why parents would give their kids away. Eventually, at 13, they were adopted by a rich family. Their personality and behavior barely changed, though. They were still very quiet and never really spoke to people, not because they were shy, but because they just didn't want to. Often they would try to figure out exactly how they felt about getting a new family, and the fact that their parents weren't actually going to come back for them. To keep themself occupied, they started fiddling with surplus of clocks their family had, taking them apart and attempting to put them back together. They did this for years and years, until they could put together clocks without any help.
Important Secrets: They know quite a bit about time travel, the multiverse theory, and psychology. They never really tell people about this stuff, though. They tend to write down all kinds of stuff in journals they either store in their room or in a pocket of their robe, from thoughts to names to events that happened.
Important People in their life: No one, really. They care for their adoptive parents, but not as much as most children would. They were never really close. They also don't have any friends.
Likes: Tea, collecting gears
Dislikes: Hourglasses, clingy people

Skills that will be useful in a Killing Game: Good with their words, agile, cunning, and observant.
Strengths: Fast runner, adept at taking things apart or putting them together, tall.
Weaknesses: Physically weak, extremely unsociable, has a hard time making friends.

Investigation Behavior: Investigates fairly lazily, tries to find info as they go along, but doesn't really care if they find any or not.
Trial Behavior: Only helpful when they want to be. They tend to try to purposefully throw everyone off track, just to amuse themself. They want to find out what really happened, though, so if they feel like it's getting nowhere they'll be more serious.
Likeliness to be a victim (1-10) and why: 5, mostly because they're extremely wary of other people. They don't make friends or allies very easily, and are quick to distrust someone. They can outrun the average person, and are a quick thinker. Fast reaction time.
Likeliness to be a culprit (1-10) and why: 6, because they don't like killing people. Only will if they absolutely have to (in self defense, usually). They easily piss others off though, so they would probably end up being a common target.
Could they be the traitor and why?: Most likely not, they don't like teaming up with other people. They would also think knowing all the mysteries behind something would be boring.
Could they be the mastermind and why?: They could. They have more than enough money from their parents for any possible resources needed, and a killing game is a perfect situation to observe how other people interact with each other and think. It would be fairly easy for them to fall into despair.
