妹のいる生活

Before I realized it, I was in a different world.

A former Japanese office worker woke up in the body of a baby.

It seems he’d been reincarnated in a different world…

Although he was born into a noble family, his mother was a concubine, so his official status was that of a commoner.

To such an individual, there was one person he wants to protect.

She was his younger sister from the same mother.

And his sister seems dead-set on never letting him go…?

The life of a reincarnator and his beloved sister begins.
