Using Magic to Become Younger-zansu

Osomatsu-kun – Season 1

Mr. and Mrs. Matsuno take advantage of de-aging magic that turns them back into teenagers, but neither of them know each other's secret. Mom starts a career as idol singer Matsuko, while Dad masquerades as a less-talked-about relative. But what are their boys to do without their parents around, at least as their good Mom and Dad selves?
