Profile

Hirokazu is one of Matsuda Takato's best friends, who eventually becomes one of the ten Digimon Tamers. Hirokazu is brash, arrogant and cheeky, though he is a brave and loyal friend. He loves the Digimon card game, and constantly beats Takato and Kenta at it. He is nowhere near the level of Makino Ruki and Akiyama Ryo, however, and is a bit of a fan of the two.
