This one is a fav http://www.mangago.me/read-manga/tetsugaku_letra/
Ballroom e yokoso (probably sleeked jr wrong but it’s on page 1/2 of the list the person posted)
Diamond no Ace....this and Haikyuu are tied for me and I love them very much.
Also please Read Slam Dunk, the development of the mangaka’s art style over time is beautifullll, also the series itself is iconic
Wow I can’t type, I meant to say “spelled it wrong” not “sleeked jr wrong”
I’m also recommending Hajime no Ippo!!!
Be warned since it’s old manga there’s a chapter with blackface in it .-.
kuroko no basket, yowamushi pedal, prince of tennis.
please please please rec any sports manga like blue lock, ao ashi, moon land, touch, haikyuu...i feel like ive exhausted the sports genre but its my favorite and im going to cry if i cant find anymore T^T
