Vinland Saga - Best manga ever! Manga authors often struggle with writing compelling, meaningful stories and characters but this one absolutely nails it.
Death note - It may initially seem like a power fantasy for teenagers but it really surprised me with how mature the writing is, although it might not be the easiest reading.
Frieren - Pretty much the queen of casual fantasy stories.
Demon Slayer - Just the right mix of cuteness and seriousness to deliver a vibrant story about saving your loved ones.
Jujutsu Kaisen - If you get bored by fights easily, then maybe this one could interest you. Story telling is pretty negelected but the fights are really technical and consistent. No bullshittery or sudden power-ups out of nowhere (with some exceptions).
Chainsaw Man - There’s something wrong with the authors brain in all the good ways. He pretty much just throws shit at a wall and it somehow turns into a masterpiece.
Vagabond - A fictionalized story about Miyamoto Musashi’s life. Some of the best character development I’ve ever seen.
