Pretty good open-ended adventure, despite some frivolousness.
Resembles "Re: Zero", but better, without stupid checkpoint restarts or hyperbolic drama.
It would have been much better adventure if not one thing that nearly spoiled it for me: half a minute or so of almost each episode is dedicated to "pervert factor" like obsession with underwear or groping, for no good reason, completely unnecessary, adding nothing to the story and just ruining the taste and style. Polluting the show with vulgarity is a disservice to audience. That problem aside the show is quite entertaining.
The story begins with a man being (re-)born in a fantasy world, retaining memory of his past life in modern Japan. Past life experience don't help him much (new world have no computers) and he have to learn a new language from scratch. He does well as a child, eventually going on awesome journey, which is what most story is about. In fact, reincarnation component have so little influence on the story that it is almost completely redundant.
