VERY good manga with a main character that is not annoying while also acts like a normal human being. The ending was NOT the best. It came fast and hit hard, but the rest of the manga made it worth the ride.




If you are uncomfortable around the idea of sex, I would advise trying to skip around the bug drone arc because the villain that time uses others 'doing it' to get himself off.


MAJOR SPOILERS FOR THAT ARC AHEAD IN CASE OF WANTING TO SKIP







The device was created by another guy who had wanted to save his dying daughter, but failed. The bugs are drones and can transmit feelings to okitenemuru. Can't remember much but that's the gist of it.


MORE SPOILERS FOR END

The story from there is good until the last like 10 chapters where there was suddenly a nuke, another plane of existence, the mc has a brother, but he's not really the mc's brother, the big boobs girl on the other side that is the sister of the girl on the mc's side suddenly sacrifices herself (maybe? i can't remember all that well) and it's one of those typical 'and everything was made normal again and all right in the world' kind of endings.
