Raizen

Raizen was the legendary God of War and the most powerful of the Three Kings. To honor a tragic vow made to a human lover, he endured centuries of starvation, a period that steadily depleted his strength. Despite this decline, his legacy continues through his descendant, Yusuke Urameshi. Even as he neared death, Raizen retained enough power to combat S-Class threats and eventually manifested to assist Yusuke in defeating Sensui before his passing.
