Raizen stands as the strongest of the Three Kings and the most powerful character in the entire series—the God of War itself. His decline, though, came from an unexpected source: he fell in love with a human woman who nursed him back to health after a brutal battle. He got her pregnant and made a vow never to eat humans again until he could see her once more. When she died before that reunion could happen, Raizen kept his word, starving himself for centuries. His power drained away as his hunger grew, yet even on the brink of death, he remained strong enough to fight S-Class warriors to a standstill.
Raizen's bloodline carried on through Yusuke Urameshi, descended from the witch doctor woman who'd saved him. During Yusuke's final confrontation with Sensui, Raizen possessed him and helped secure victory. Before dying, Raizen pushed Yusuke hard—train for months, surpass me, claim my kingdom before I'm gone. Raizen didn't make it that long, but Yusuke inherited the kingdom anyway.
