Thoroughly enjoyed the first 600 or so chaps (first major arc). The teacher trying to bring his powerful wayward students under control was well written, though mc depends way too much on system items. I think the end of that arc was a good place to stop, because after that I gradually lost interest. It's just generic fighting more powerful new enemies, DBZ cr*p. The students who were very independent have just been relegated to side characters who the MC is hard carrying now, and it doesn't help that any potentially challenging scenario is just solved by using a death card. I don't feel any stakes at this point.
The world building is interesting (regarding lotuses), but the characters in the later parts are just not interesting enough to carry forward the story.
