The Nanny's Everyday Disasters

Asano Ryo, who died young in a hospital bed, gets bound to a childcare System.

The System says that if he wants to stay alive, he has to obediently complete his missions. Otherwise, Asano Ryo will be sent to hell.

So Asano Ryo gives in and embarks on a journey through different worlds, raising children.

He's raised a workaholic from the Port Mafia, served as an orphanage director, and raised a quiet boy from the Taisho era...

The kids he raises are all terribly insecure, so Asano Ryo has to tell them over and over, "Your dad loves you most of all," "You're your dad's only kid," and "Your dad will never leave you."

Asano Ryo thinks his only task is to transmigrate through time and raise kids, but then one day, the worlds he's visited merge.

Faced with his kids accusing him, "You said I was your only kid!"

Asano Ryo's cover is blown.

To make matters worse, the merged world is unstable. Just then, the System updates and gets revamped into a "World Protection System."

Asano Ryo: ...

I'm just an ordinary babysitter, so why are you making things so hard for me?!
