When it comes to personality, Ruuka could be described as a tad hot-headed. He's forward, often boisterous, cocky, and quite competitive. Funnily enough, he is also easily flustered - which doesn't bode too well for him considering he has a silly chuuni-ish idea that he's more capable than he really is. But what he lacks in his human form, his esper form is where he really gets to revel in his self-confidence - as he has something to actually be confident in. It doesn't help that his esper form makes him a tad more aggressive.

This isn't all to say that Ruuka is incapable of thinking critically, however. While he most definitely makes some rash decisions sometimes, he isn't dumb. He knows if he's a little too far out of his league, but sees most chances as one worth taking - maybe it's an ego thing. Nevertheless, he can strategize - even in his human form he has a sharp eye for details. Notably, Ruuka is not very well-versed in reading people, and as such is kinda gullible, and sometimes awkward. He can't read social situations very well.

Ruuka's story is a simple one - not all that special. He's an only child who was homeschooled by his birthparents, and led a pretty normal life up until a couple years ago. Born in the states to a mother and father who were Irish and Japanese, respectively, Ruuka was never fortunate enough to have siblings, cousins, or really any other family aside from his parents. This, alongside the fact that he was homeschooled, left almost all of his social interaction to be had on the internet, over videogames and other similar mediums. Fortunately, his lack of a social life was the heaviest of his life's troubles. His parents were wealthy, one a doctor and one a scientist of some kind, which left Ruuka rather spoiled - at least for material things.

Said wealth, however, was not entirely a boon - depending on how you looked at it. This wealth would eventually, if indirectly, lead to Ruuka's introduction into the supernatural world. At some point around two-and-a-half years ago, Ruuka and his parents moved homes. They made a new nest in an old, though well-kept, mansion. Said mansion was huge - simply far too much for the three of them alone to explore. Yet one particular, secluded part of said mansion called out to Ruuka. An attic-ish area with a bay window and old, canvas-padded seats was where Ruuka found himself drawn. It was there that he'd find an item that would change his life -- his grimoire. A small, black ring sitting alone, right beneath the window. After that day, he found himself thrust into the world of the supernatural.

It was something he hid from his parents - but he was, fortunately, lucky enough to quickly learn to keep himself alive without outside help. He never received proper mentorship from anyone in particular, but is almost entirely self-taught in his prowess and knowledge of the supernatural - picking up information, details, and whatever else he might need over the years by his lonesome. He has established himself a couple contacts - as he does solid work as a Freelancer - but is ultimately a stranger to most. Luckily, he is quite wealthy due to the gross fortune of his family as a whole - which is pretty damn useful.
