In a far-off corner of another world where only nobles can use magic,
a certain thirty-something salaryman is reincarnated as a five-year-old village boy named Ren.

For him, the slow-paced countryside life is peaceful and enjoyable—
that is, until a group of adorable but terrifying little angels (a.k.a. troublemaking children) takes a liking to him.

One day, while thinking of ways to slack off more, a monster suddenly attacks their once-peaceful village.
And when the problem children are put in danger, the usually unmotivated Ren unleashes a hidden power he's kept secret—just to avoid getting dragged into more trouble!
