Hiroshi Miwa

Hiroshi Miwa considers himself Akuto Sai's most dedicated follower. An energetic boy driven by devotion to the legendary hero, he frequently annoys Sai by jokingly claiming they are brothers and calling him the "Demon King." While his persistent antics can be bothersome, his intense admiration for Sai's power defines his personality and his role as a loyal, eccentric companion throughout their journey.
