In "My Ribdiculous Reincarnation," the unnamed protagonist becomes trapped in an endless cycle of reincarnation within an alternate world where individuals can select their next lives. However, because popular choices like "Demon King" or "Hero with Cheat Skills and a Harem" are in such high demand, the waiting list has ballooned to an incredible 50,000 years.
Rather than wait that long, the protagonist opts to reincarnate into increasingly bizarre forms—first as a hero's rib managing a harem, then a hermit crab, a vegetable, and eventually an explosive device meant to disrupt happy couples.
