sayako- very mature because she was forced to be. she attended her first funeral when she was 9. she grew up pretty fast. by the time she was 12, she was as mature, if not more mature, as an edgy 14 year old.
matt- pretty mature, just because he has to take care of his younger brother and the rest of the lil shits that Tk's friends with. he's a very mature person, who thinks very rationally.
joe- do i even have to say? hes very mature because of his anxiety.
tai- he's mature because he takes care of kari. also because he has mental issues that he has to deal with, that caused him to mature faster.
hitaru- hes very mature. mostly because of his trauma. he's mature but still childlike.
mimi- semi-mature. she's still quiet and childlike, mostly full of that childish wonder.
Sora- VERY mature.not for any reason, she's just always been a mature person.
Kari- pretty mature? but still young and innocent. she isn't /that/ mature,, she just knows when and when not to be childish.
Tk- not very mature, unless he has to be. he's mostly childish and calm.
ken- very mature. he's almost always mature and calm, unless being a dumbass w/ the group.
