Jaki Daigouin

The leader of the third years and the Otokojuku representative. Known as the Emperor of Otokojuku, he has ruled the school for over 10 years. A master of Daigouin-ryuu and Kikou Touhou. In his earlier appearances he seemd as large as a daibutsu, but it later seems as though his fighting spirit gives off the feeling that he is that large. He has won the Dai Ishin Paren Seiha three consecutive times, and he uses his power to defend his position. In the past he challenged Edajima to a duel but suffered his first loss, and came to realize the level of Edajima's greatness. Before his fight against Spartacus in the Tenchou Gorin, he entrusted the proof of his position as Otokojuku representative to Momo. He continues fighting even after having his heart pierced, and kills himself while finishing the fight with his Shinkuu Senpuu Shou. (Source: Wikipedia)
