The Gutsy Togashi's Tearful Confession! Daigouin Jaki Is My Brother's Murderer - S1.E24

Togashi continues his passage, while coming under attack from Dokugantetsu, until Daigouin Jaki stops them. He allows the First Years to pass to the third and final chamber. Meanwhile the Third Years look into Togashi's past and find that he wants revenge for the death of his brother. Togashi tells the First Years that three years earlier, his brother was killed by Daigouin Jaki six months after enrolling at Otokojuku, and that he enrolled at the school to take revenge. Toramaru takes the lead against Baron Dieno in the electrified Chamber of Purple Lightning. Toramaru defeats Baron Dieno and the four First Years are allowed to progress, but Togashi locks the others out so he can confront the giant Daigouin Jaki alone. Jaki tells Togashi of his brother's death in the Great Trembling Conquest of the Unified Eight. Togashi attacks him but is easily beaten. He then reveals that he has 10 kg of dynamite strapped to his body, turning himself into a human bomb.
