Absolute trash. MC who is the most powerful warrior in the universe is forced to go back to school and train some random girls... This has to be the 1000th manga with the exact same plot. It's so generic you could swap in pages from any other series and not even notice. Every chapter has MC showing off how amazing he is while simultaneously complaining about wanting a "quiet life" and also building a harem... It's silly school drama with zero stakes. MC hides his identity at school for all of 30 seconds before revealing he's an all powerful warrior superman. MC trains his classmatesby telling them to "concentrate" and they become gods overnight. MC doesn't understand how "normal" things work because he is too powerful. Everything about this series is predictable and boring.
