I need manga recommendations to read preferably adventure, sports, and slice of life. I don't like ecchi, harem, romance, ntr, hentai, and overpowered mc so please refrain from suggesting animes with the genre stated above ( ╹▽╹ )
World trigger? If you haven't read it, it's categorized as sport. The mc holds more of a supporting role rather than the main attacker. Maou-jou de oyasumi Spy x family
Slam dunk will have a movie adaptation this year, maybe you could pick it up if you haven't? Sousou no frieren (slice of life/adventure) 7 seeds (adventure, really great after you get used to the manga style) Blue period is great too.
+1 for Slam Dunk As for others, if you don't mind some old ones: Yuru Camp Breakwater Club Diary Sleepy Barmaid Flying Witch Bartender (+) Shirogane no Nina (+) Eyeshield 21 (+)
