Dying to read . Can anyone suggest some manga or Light Novel series like below?

1) Self sacrifice or social kill plots. For example plot like Yuu Ishigami from Love is War.

2) Whole class drifted plot.

3) Series like 7 seeds with multiple protagonist and plots meeting each others at the end of the series

Thanks

For #3, Boku no Chikyuu o Mamotte has a similar sci-fi feel.

Also, Otoyomegatari has lots of plotlines but it hasn't ended yet so no idea if everyone will have met by the end. Historical series, not sci-fi.

Could you explain what you mean by "whole class drifted"? Do you mean they drifted apart after high school or what?

Thanks. Would try Boku no Chikyuu o Mamotte.

Are there any similar good manga or LN like Ingoshima, Eden No Ori, Mouryou No Yurikago or 7 Seeds?

Drifting Classroom, it's pretty old, and very dark.

First of all, I would suggest checking out other manga by some of the authors you read - EX - Shounen Hyouryuu by YAMADA Yoshinobu was good, and everything I've read by SANBE Kei was good.

I've read some other series like what you describe, but I don't recommend some of them. If you just want to find more stuff with those themes & genres, I suggest an advanced search, the tag "Survival" will probably turn up a lot of stuff you might like.

The only other series I can think of that stands out is Dragon Head.

I'm not sure if it fits your description but what you said brought to mind
Arifureta Manga Novel

Some others
Lonely Attack on the Different World Manga Novel
Monster no Goshujin-sama Manga Novel
Dungeon Reset Manga
Goblin Slayer Manga
Btooom! Manga

You might like
Jungle Juice Manga
Gleipnir Manga
Omniscient Reader Manga
Rising of the Hero of the Shield Manga Novel
Dr. Stone Manga
The Executed Sage Is Reincarnated as a Lich and Starts an All-Out War Manga

Most of the manga/novels I would suggest are single person perspective I don't read alot else.
