Hugging this character: Yes, though you will probably embarrass him
Kissing this character: Yes, though he will flail a lot unless it's either a chaste kiss on the cheek or from a lover. And even then he might flail.
Flirting with this character: Go for it! He'll likely be flustered by it, though he's used to it from your character or likes them back, he might flirt in return.
Fighting with this character: He comes from a hack and slash canon, so yes. He might try to talk you out of it if there's a better solution, but otherwise let's get ready to rumble.
Injuring this character: As long as we discuss it before hand, yes. I'm not okay with torture porn, but I'm willing to put him through a lot.
Killing this character: As long as we discuss it before hand.
Using telepathy/mind reading abilities on this character: Yes, within reason. Discuss it with me first.
