Kakure Tensei @COMIC

Synopsis

In a remote corner of another world where only the nobility can use magic, a thirty-something office worker is reincarnated as a villager named Ren (5 years old). He enjoyed a laid-back life in the countryside, until the Cruel Angels (Pretty Angels) took a liking to him... Even though he wanted to be lazy, he ended up playing hide-and-seek, reading to them, calming them down, and more from morning to night, all because he was so caring! One day, while he was trying to think of ways to be lazy, a monster suddenly appeared in the peaceful village. When the problem children were targeted, the usually unmotivated Ren unleashed a hidden power he had been hiding to avoid trouble! This is the heroic tale of a carefree reincarnated boy who, with a sense of relief, babysits (and saves the country)!(Source: Corona EX, translated)
