[ Shuu makes no secret of the fact that he doesn't like anyone.. purely on basis of the fact that they're human too, most of the time. But that doesn't mean he can't harass them all the same like this, huffing a little (like a little kid) at the man's response. ]

An old man like Senkimaru-san to-tal-ly has no taste in having fun at all.. [ Are you trying to insult two people at the same time here, Shuu. Except the difference is that with Senkimaru it's - mostly - just genuine teasing, while he doesn't feel bad at all over insulting random people without a hint of fondness in it.. ] Shouldn't you be the perfect person to tell him what to do then?
