Raise Ikuzou (育蔵来世) was a Shinigami Teacher and a Gold License Holder.
It had been decided he would have to go to the Wheel of Reincarnation, so in his final lesson, he hoped to raise Sabato’s license rank before having to retire. He tasked Sabato during his exorcism training supplementary lesson to do 100 purifications before sunset. Although Sabato did not want to repeat a year, he ended up using his "Leaving Stroke" technique on 200 spirits to leave them harmless and allow the pretty girls from an All-Girls School, who happened to be training in the same training ground, to claim the purification for themselves with just one strike, to be thanked by them. In tears, Sabato's teacher vents his frustration, revealing what he hoped, which made Sabato feel some remorse. So he offered him a chance to inherit his gold license in a duel, for it is legal for one to defeat a gold license holder and inherit his license. Just as the battle was about to begin, the girls Sabato helped earlier arrive to cheer him on, which distracts Sabato letting his guard down to wave at them, but as he drops his scythe, it lands on the head of his teacher, allowing him to win the battle and inherit his gold license.
