Recommend me any good manga

https://anilist.co/search/manga

Some nice Manga I read:
Vagabond
Otoyomegatari
Arifureta Shokugyou de Sekai Saikyou
Bakuman

Both of those have great anime adaptations but I also recommend you read the manga from the start since both are wonderful experiences in their own right, and the anime only cover a part of the manga
Kaguyasama wa Kokurasetai Tensaitachi no Renai Zunousen
Akatsuki no Yona

This has a currently airing anime but is great nonetheless
Kyokou Suiri
