In many regions, including the US, Viz Media offers the Shonen Jump app and website. This is the gold standard for reading modern manga.
Volume 1 introduces us to Hanamichi Sakuragi, a tall, red-haired, and notoriously hot-tempered delinquent at Shohoku High School. Hanamichi has a history of rejection—he has been turned down by fifty girls in middle school. When he starts high school, the last thing on his mind is basketball; he is mostly interested in finding a girlfriend.
