Full name: V Alioth. He doesn't want you to know what the V stands for and if you try to ask him he will use a different false name every time (and his actual full name is spoilers so I'm not going to post it here).
Age: older than you might think (physically 16)
Occupation: no one knows if he actually has an occupation, but he's incredibly wealthy. (he gambles a lot and has accumulated a significant fortune.)
Family: none (he doesn't consider himself to have family, at any rate; they would have disowned him if they knew he survived.)
Best friend: Alioth doesn't have friends.
Love interest/Ideal partner: Seriously it would be dangerous to become intimate with him. Bad things happen to those who try. (and he's aro ace anyway)
How they met: Alioth was engaged at one point; it was an arranged marriage which was common where Alioth came from. And then they died horribly on the eve of the wedding.
Favourite food: fancy desserts with chocolate in them, and things that taste like blood.
Hobby: being unfathomable and cryptic, watching people (especially those he confuses)
Person they look up to: no one really
Biggest wish: to remain free.
