Manga Botsuraku Youtei Nanode, Kajishokunin Wo Mezasu

After his death, the protagonist of the story was reborn as a character in an old game that he once played long ago. According to the plot, this character will die along with the villain, after spending the last years of his own life with her. At the same time, the game does not tell a word about why they met, and how he generally came to such a life. However, our hero does not care at all. Since he does not want to engage in banal farming and live in mud, he goes to conquer other places, and also wants to master the profession of a blacksmith, because in a past life he was strong in this.
