Grinder

As a time traveler who doesn't know whether it should be considered a success or a failure, he can't help but correct the wrong understandings of those around him... "Mistress! Come and help!" "Mistress! Are you okay? I'm waiting for you to start working!" "Mistress!..." … "Young master, Mistress! The nickname I gave myself is Sanshi! Sanshi! If you call me Mistress again, believe it or not, I will throw your integrity into the crusher!" "Okay, mistress, yes mistress." … Anyway, it's a story about a young man who keeps struggling and saves worlds along the way. This novel and its characters are purely fictitious.
