Lang Yue's Questions (2)

Recent updates of some manga are causing tears to us readers. Well, who wouldn’t crying after reading the death of one the characters you became fond of like in Kimetsu no Yaiba and Yakusoku no Neverland, to name a few. One of these days, I think I’ll be crying to Boku no Hero Academia too (but I hope I won’t). Anyways, can you recommend me some other manga which has the same feels as those that I mentioned? Something with great plot, character growth, some actions, and lastly with characters you can’t help but be attached with (then be killed....) <—- I know this one is kinda weird but because of this the manga becomes unforgettable for me and worth reminiscing like Koro-sensei from Assassination Classroom.

I've been really interested with stories about reincarnation, time-travel, and adventures in another world. And here's what I've noticed, there's a lot of webtoons and manga now with this kind of plot so isn't it much better if a genre for reincarnation/isekai is created? It's kinda tiring, asking what manga or webtoon is similar to this and that and I believe it would make searching easier for reader with the same interest as me. Am I the only one thinking about this? Cuz honestly, I hope I'm not the only one.
