Can't. Samael is the actual name of a demon and so is Mephisto. I searched Samael because I'd probably get 更多 awesome pictures...so disappointed it wasn't my dearest husbando... So just take badass looking guy instead. (Still a little upset that it wasn't Blue Exorcist Samael)
My 最喜爱的 character is also the protagonist of the first 日本动漫 I *really* liked. It's still (and probably always will be) my *very* 最喜爱的 OVA and my 最喜爱的 日本动漫 of all time! I'll add the first pic 谷歌 threw at me hehe. Even his name is cool—Jubei Kibagami (牙神 獣兵衛). It's interesting to see everyone else's 收藏夹 too! Cool question! Thanks for posting.
