Yukio Hirayama

Yukio Hirayama also know as Fake Akagi, was the representative mahjong player for the Kawada Yakuza group after he was discovered and introduced to them by Yasuoka. Despite his physical resemblance to Akagi, his playing style is based solely on mathematical calculations and probability, in contrast to Akagi's natural gambling insight, inhuman luck, and psychological manipulation abilities.
