He's gotta be Tsun first before he shows off his dere.

As for the telepathy thing, I guess I'll compromise and say that for most people who at least have an active aura going on, they may feel something strange in his presence if he's trying to read their mind. I just don't want people to get this feeling and then realize he's reading their mind, least of all when all he's doing is reading and not trying to communicate. I hate it when I play a telepath and people just suddenly start discovering their ability to ward themselves against mind reading or become able to pin down exactly who is looking into their heads just by the "strange feeling" they're getting.
