An isekai about a boy who experiences an endless cycle of reincarnation.
The story takes place in a universe where people are free to select their next form. However, the waiting list for popular roles, like "Demon King" or "Hero with Cheat Skills and a Harem," has reached 50,000 years due to a recent spike in applications, so the protagonist decides to reincarnate into increasingly strange forms because he refuses to wait. These roles include the rib of a hero in charge of a harem, a hermit crab, a vegetable, and even an explosive used to blow up blissfully happy couples.
