Just constant powering up with a sprinkle of battles, a lot of filler every chapter without much emotion. That's probably what gets me sad about this; you have such an interesting world, but all you're doing is scraping the surface. No true emotional ties, no development of character, no interactions beyond power. It gets stale real quick.

Started mid, but after the first isekai to Under One Person/ The Outcast, MC just kept on hiding in bushes ego-stroking himself off about how smart he is and not doing anything except boringly following the boring stations of canon. The plot was boring enough as text, but now it's just obnoxious.

Justice! Bonds! Wisdom! Death! Oh yeah~~!
