Toritsu Mizushou!

He never wanted to kill her, he's a chuunibyo who conflated "murder" as "affection".

well , how do I say this , this was certainly one of those mangas with a different take over the isekai genre , tbh this felt more experimental than interesting . so for now I now I will give it a humble 6/10 but I feel it has enough potential to become an enjoyable 7/10 if it finds it's bearings and can realize what it actually wanna do with the MC in the longer run.

aloalivn.com has up to 291 but again disgusting translation quality.

You are right - most of these are horrendous shit (this included) and the hunter/tower/smurf/returner stuff has become the Manhwa equivalent of Isekai, but there are some good ones too. You can make a powerful MC work too if the rest of the story works.

Try "The Legend of the Northern Blade" like ghqste recommended or "Latna Saga".

i want a gf bros

This is all non-canon to the novel. Everything that's happened with this puppet arc shit is webtoon original garbage and it shows. They are padding out the story to milk it.

The concept is exactly the same as Darwin’s Game, except the mc is a bigger loser. He starts off as a trash bottom rank healer with a super op alt, except that when he's expected to fight, he becomes trash, then miraculously wins. I just can't get a grasp of his actual power which is veeery annoying.

Why not report it?

i feel like i've already read ch.29 before

He chose imouto.
