Throwaway manga. You would get more entertainment from reading the dictionary.
There's shallow manga, and then there's this trash. Dude saves the world in the first couple pages and then cries because hes homesick. Then he goes home and cries because he's way too powerful. Then he does random stuff and cries some more. This type of manga still surprises me because it proves there is no floor in the isekai genre. If you ever thought "it just can't get any worse," well, here you go. Artwork is about at the level of a Kindergarten class. I want to say this is some kind of "quota" manga to pad pages but it's not even good enough for that.
