I talked about Ken'ô (Ken-Oh) from Hokuto early, but Kenshirô boils my blood.
As martial arts practitioner, his strenght, determination and self-control is an inspiration.
In fact, I can't say who is the best - Kenshirô or Ken-Oh.
For me it's definitely Kaoru Yamazaki [Welcome to the NHK] ^^
I'm just like him, personality, glasses, otaku-ness, extreme love for Purupuru pururin and so on. xD
I'm gonna be a freak and say Tohru Honda from Fruits Basket or Miyazawa from Kare Kano, probably because they're personalities are so enjoyable and completely adorable ^___^
