Places someone might find the character? Things they might be doing? Jun is in the library a lot. And I mean a lot. He can also sometimes be seen in the park, or at home (he lives with Midori, Orihime, and Nakama). He… needs more places to be pushed to.
Is the character in any IC group, including the school? Details! He takes a swordsmanship class at the school (with Cain). Other than that he's not really in an IC group, though he might pop up at sewing meetings since his housemates are all there. Not to sew, though.
What kind of person does the character get along with? He's a very… tsundere type of person. He has a very tough outer shell, so patient people are the kinds he gets along with most. They need to let him rage before they get anything deep or substantial out of him. He's trying to get closer to 'military' people though, because he wants to try to understand his mother a little (who he never really knew). He's also still… adjusting to the magic thing. :(
Is there any type of CR you feel the character is missing (e.g. romantic interests, mentor figures, etc)? Mentor figures up the wazoo. He needs a father figure (Cain is sort of the one he's latching onto a bit) and… well. He won't admit he needs a mother figure but he really really does. And one that doesn't push him to do things, but is just… there for him.
