I’m a former hero returning from another world, but I was involved in a death game

Eh, it’s slightly sub-par as a parody, mixing two overused genres to make your own funny parody story (the dude’s name is literally Ise Kai(to)), but so far it’s just reusing the same “op isekai hero defeats people who think they’re strong but are weak compared to him” on repeat. The two genres don’t really mix when a dude with supernatural abilities who easily defeats average humans who are in charge of the death game, which also defeats the purpose and suspense of the “death game” genre. Normally its a man vs. system/man, as he fights tooth and nail against his will for the sake of survival, and to get revenge on those who forced him in this hellish situation, but with his powers, at the author’s whim he already got to a situation where they could all escape and live happily, but they decided to stay in order to prolong the story, the protagonist could probably just “sense” where the mastermind is using generic Isekai abilities we know exist in other stories and have no explanation about how he obtained them from the Isekai world. Already getting a little boring, so unless they do somehow change the way the story’s going it’ll be over in 10 chapters with a happy ending and everyone goes home. Also the characters are mostly generic, and fit their stereotypes to a T, so the story isn’t improved with interesting, unique, and likable characters to make up for a lack-luster story (unique characters are also important in the making a good death game genre story as well). They’ve already almost confined their plot line to an easily predictable and monotonous outcome, unless they either make the mastermind a villain also from an Isekai world or do something outrageous to the plot that’d completely change the entire plotline set up so far, it’s more of a time waster manga of combining two overused genres with an author’s power fantasy than a good manga you’d get invested in the storyline and look forward to every chapter getting released.
