Well, its not my cup of tea, only ff I know which goes with some tragedy setting is jjk: tragedy life simulation - MC there is serius nutjob(in righteous sence~ more severe case than Higuruma was).

Just second? That dialogue lasted mor than minute

So if his ability makes it possible to create cards from PL anime characters, what do normal people rely on? Standart templates? If so, how is dude going to explain himself ?

From perspective of MC having some screws lose?

Honestly? I once read similar novel and my biggest question about genre/power system is how the hell MC's knowledge gives him advantage? Like realy? People in otherworld can't come up with story for making a card? Its not like the actual basis for Card Creation is existence of lore in reality... Its just as you said another type of plagiarism fanfiction with MC's knowledge getting him power instead of money.

Book itself is good but translation.... Honestly you would be better off reading this on wtr at least names can be changed there and there is no one line fragmentation in second half of chapters.

Finally normal chapter titles

Hell, this is most ridiculus AI translation I ever seen, what is going on? Writting its own settings into story?
