i don't like answering someone who's already been said. so even though i wanna answer Hitsugaya Toushirou (the best, cutest, hottest, coolest, most awesome, perfect, lovely, adorable, incredible, outstanding, special person in the anime world) i won't.
and since Uchiha Sasuke was taken too i have to say Natsu Dragneel... don't know why... he's just cute.
I was going to be a smartass and post a Pokemon and call it a boy but I won't XD I don't feel like looking up pics so I'm gonna randomly pick some dude I have- ZOMG *remembers* Oli-bo! <3 Aka Oliver (Vocaloid) He's so freaking adorable *_*
