I would like to slap all the stupid bad guys, who always tells their plans to good guys before "killing them". And it always ends up that the good ones survive . Why are they taking time and explaining all their plans?
Also I would like to slap Orihime from Bleach. Just to say wake up take Ichigo if you want him and don't be so shy
Hinata from Naruto for the same reason.
All vampire characters, who doesn't want to drink blood, even if they need it.
Tamaki from Ouran Host club for being so stupid and not understanding his own feelings.
Yuuki from Fruits Basket for not killing Kyo
Alucard from Hellsing for obeying humans
Lucy from Elfen lied for not killing everyone around and falling in love with such a not cute at all guy
