Absolute trash isekai. About as generic and shallow as you can get. MC who is the most powerful existence in the universe is forced back to school... This is probably the 100th manga I've read with this exact same setup. There is practically no story here. The manga is so generic it could be copy and pasted from anything. Within the span of a single volume the MC has a harem, taken over the school, and killed the most powerful demon. Every single line of dialogue is predictable. Character development is nonexistent. Again, how or why would anyone care about these characters when they are literalsuper gods? The school drama parts are silly but contain no comedy. In the entire manga I don't think there is a single chapter worth reading.
