Ritsu inherited his sixth sense from his grandfather, along with a demon guardian named Blue Storm. Strange things just seem to happen around these two, and it's left to them to get to the bottom of all these mysterious events. Each story is independent but features recurring characters you'll come to know and appreciate as they, each in their own way, try to deal with things 'not of this world'. (Source: MU)

The protagonist of the tale, simply referred to as I, experiences an endless cycle of reincarnation. The narrative takes place in a different 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. The protagonist decides to repeatedly 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. (Source: MAL News)
