Inmates
Honey
Honey is Trois's cellmate and closest companion. It is highly likely that they met in prison and have stuck together ever since. They bicker sometimes but Trois mainly just likes to tease and joke around with Honey. Trois is very understanding of the type of person Honey is and accepts him, anger, stubbornness and all. However, he does not expect other people to as he knows full well that Honey's harsh criticisms and attitude can be taken the wrong way. When that happens, Trois is apologetic about it and will usually let Honey know he's stepped out of line by telling him he's being "really unattractive right now."Jyugo
Trois became friends with Juygo after Trois started spending time with Uno. He admires Jyugo for his skill and is highly impressed by his abilities. He advises him not to doubt himself about his skill because while he may not be skilled at much else, his ability to, unlock any door, crack any code and solve any puzzle is nothing short of amazing. He also advises Jyugo to apply himself more to other people and tells him that way he will be able to understand other people better as well as understand himself.Uno
When they first met, Trois disliked Uno because of his cockiness and talent. When they competed against each other in Hyakunin Isshu in the New Year Tournament, it frustrated him that Uno could read him so easily and figure out his tells when he thought he didn't have any. That and how Uno had gone from doing poorly at the game one minute and flooring Trois and Honey in the next and seemed to master a game, that must have taken a long time for Trois to master himself, in less than a minute like it was nothing. However, after getting to know each other a little bit the two are now on good terms and are beginning to develop a friendship.
Guards
Kiji Mitsuba
Trois is a lot closer to Kiji than the four from building thirteen are to their supervisor. Kiji gives him and Honey special treatment because of their handsome faces and the two hold him in high regards. They look up to him like a role model and have a high amount of respect for him.
