Age 737. Whis, the Guide Angel Attendant of Universe 7's God of Destruction, had been trying to raise a certain child for some weeks, who had landed on Beerus's planet. However, realizing his incompetence at doing such a job, he ended up thinking about someone who he could have pushed that task onto. In the end, he opted for his eldest sister, Kusu - Attendant of the Universe 10's God of Destruction, Rumsshi - to take care of said child. Kusu, despite her childish looks and playfulness, was the wisest of the Grand Priest's children, always advising both the Supreme Kai, Gowasu, and the God of Destruction, Rumsshi, on good and evil, not to mention that she had a caring side to her. When Whis arrived on Rumsshi's planet, much to his sister's surprise, with a goofy smile he presented to her the infant... A Saiyan from Universe 7.

Kusu: "Hehe~ he's so cute. But... Whis, he's got a tail. Are you sure he's not actually a monkey?"
