I mean come on, a chef being able to make clones to help with cooking, cut through anything to help cooking, and more. If that isn't generic cheat/op isekai protagonist, then I don't know what is. Btw this is not the main character, just one side character, but most of them get similar treatment.

He starts with a whole class, kills a few who threaten to kill him. That's fine because it is easy to digest. But then around chapter 100 they start a death match between them all, and everyone in the class was killed at once by a bomb one of them created. Even the person who made it was killed. Was there a need for that? Especially because MC was about to kill the one who threatened them into the death match, and if that person died there would be no reason to fight. It wasn't entertaining, nor interesting. Of course the MC could have easly stopped it, but he didn't because he felt it would be spiting on the person's resolve to create the bomb. This is where his odd values really start to spoil things for me.

I get it, all his classmates had to die eventually due to their situation, but throwing them all away at once is just... boring. I would have much rathered he killed them one or a few at a time after they actively got in his way on his quest to get home. It just feels like there was so much missed potential there.

they die, instantly.

When the 2nd translation group took over, they kinda screwed it up. Half of the later chapters are missing, so I had to scavenge on pirate sites for the chapters and those seemed like they were machine translated so it lowered my reading experience by a lot...

A lot of them also die.

(they even managed to sneak in a villainess at the end)

he casually kills millions of people to kill this one guy permanently.

First, I love how the author knows how this is a cosmic horror story. Once Yogiri kills someone, that's it. No going back. No revives, not even turning back time will bring anyone back to life. You'll have this long story about a character who's the MC of his own story, but no one is exempt from death. Even gods have to face their own mortality through his existence. This is nicely shown when gods divide themselves into two factions: the young reckless ones who cause a lot of trouble (like we mostly see throughout the story) who doesn't know of it, and the old mature ones hiding away who knows about it. The main lesson you could take from the novel is that don't act arrogant, because you never know just when you'll meet your end. No matter how strong, smart or determined you are, all are equal in the eyes of death.

Another thing I like is how MC's power work. They just die. No fancy thing happening, no splashes of blood, no heart attacks, no bleeding, no grotesque body horror mutilation. They just die. It feels way creepier that way. You know that thing you encountered is way too beyond comprehension.

Tomochika is also a good heroine to pair with Yogiri. Sure, a more humane heroine would probably add more story tension, but it would remove the absurdity of Yogiri's existence. With her, Yogiri can have someone to bounce off of during the whole adventure while keeping the horror aspect at full force.

inevitable death

This world has been invaded by japanese heroes with cheats. The sages was descendant of the old heroes or summoned japanese. None of the sages has good intention. Even the one who summoned the heroes were giving a first test for the LV 1 heroes... defeat a high level evil dragon. And there already 2 dead students (heroes) at the begining. Those students were students that doesnt have any cheat at all. The other students happily sacrifise non-cheat skills students just to stay alive from the evil dragon. And then the dragon just died after the MC tries to save big b**bs classmate by looking at the dragon and said "die".

The MC got mysterious power that can kill anything. In fact he could sense bloodlust, killing intents, and He can kill his foe's that hides deep in faraway dungeon. Even the MC's "family" were celebrating freedom from the world crisis just because the MC was transfered to another. They screamed "the world is now saved from that Monster!"

The Heroine was s*aved by the MC not because the MC's cheat. The heroine got different cheat from her ancestor and some alien robot.
