My Daughter Left the Nest and Returned an S-Rank Adventurer volumes 1 & 2
Story about an adventurer who retires young due to an injury, only to find new meaning in life raising an abandoned child as his own daughter.
I'm liking it so far. It's a nice heartfelt story, mostly pretty chill. There are some subplots involving demons and politics and such, but a good chunk of the story focuses on the close relationship between the father and daughter.
Sounds interesting. I remember really liking A Story About a Droid (this is a manga, not a LN) and it has a similar premise but a very different setting. I will check it out!
