Keitaro Kitamura

The innocent boy participated in the first preliminary round of the Ryuho Tournament, and although he was younger than Kei, he displayed outstanding intuition and demonstrated remarkable skill as a mahjong player on the main stage. His pure love for mahjong reminded Kei, who had once mastered the game, of its true joy. Although the boy managed to advance through the first preliminary round, a tragic misunderstanding occurred: by coincidence, his registered name was "K" and his results surpassed Kei’s in the tournament. This led to him being mistaken for Kei, and as a result, his entire family was mercilessly massacred.
