My name is Kazufumi Nabukura (23 years old), and I work at a black company. As you might expect, the constant stress of working in a hellhole got to me and, in the middle of the night, I died from a heart attack. Then suddenly, I woke up in an empty space next to a goddess, who simply told me that I would be reincarnated.

At first, I thought this is a miracle - after all, being reborn with all your thoughts intact is a cheat situation, right? And so I was reincarnated, pushed straight out of my new mother as a newborn baby (0 years old).

But wait… why can’t I see anything well? Why can’t I move? In fact, all I can do is eat and cry and soil myself! Could it be… that being a baby is even harder than working at a black company?

First starting out as a Twitter webcomic before being serialized, this part-comedy-part-educational childcare manga - supervised by an active pediatrician - aims to describe what being a baby is really like.
