@Lily-Garden it’s sports anime. Sora is a freshman at Kuzuryū High, determined to follow in his mother's footsteps in basketball. However, he finds that the basketball club isn't quite as enthusiastic, consisting of delinquent students who never want to practice. Sora is already at a disadvantage, being much smaller and weaker than his peers. This doesn't stop Sora, his dedication inspiring the other club members-- or to-be teammates-- to give basketball their all. It has an anime and its supposedly over 600 chapters long but I haven’t found anything.
