Bocchi Tenseiki

A 29-year-old unemployed man, isolated and distrustful of others, attempts to rescue a woman from an assault. He is stabbed and abandoned to die, cursing humanity as he fades. Upon regaining consciousness, he discovers he has been reborn in a different world as Ash Hawkwood, the second son of a minor noble family. This world includes magic and spirits, but he possesses no natural ability in "True Magic" or sword fighting. The narrative follows his efforts to establish an empire using his own abilities.
