Post an anime guy who bạn find to be a naughty boy

Sanji (One Piece)

My definition of naughty may differ from yours, but I think Gajeel Redfox is a bad boy (in a good way LOL) cause he's really tsundere and scary. He has a soft side, but very rarely shows it.

Shun Bakugan

Hak from Yona of the Dawn. Oh boy he's naughty.
