It's cheating if we mention traps, no? Seriously.
No.1 for me is Watarase Jun from Happiness.
Yes, that's a guy. This is why traps are cheating.
Two? Let's say...Shidou Mariya from Maria Holic.
He even has an identical twin sister so we can just pretend...
Guess I'll mention Haku from Naruto, but I'm so convinced Haku's a female that it seems wrong to mention 'him'.
