Character:

Saito has become a better-known figure among young anime fans in the West since several anime and manga series used him as a character. The popular Rurouni Kenshin series portrays him as somewhat of a rival character, Saito Hajime, once a mortal enemy of former imperial assassin and protagonist Himura Kenshin, and eventually an uneasy ally.
