The Slam Dunk anime covers Shohoku's formation and their journey through the Kanagawa prefectural tournament. Key plot points include Hisashi Mitsui's return to the team after he and his gang attack them in the gym. Initially an antagonist, his tearful plea to Coach Anzai, "I want to play basketball," marks a major turning point, solidifying the team's final roster. The team goes on to have a fierce rivalry with Ryonan High, led by the prodigy Akira Sendoh, and the reigning prefectural champions, Kainan High.
Shohoku loses a nail-biter to Kainan, largely due to a critical late-game passing error by a distraught Sakuragi. This forces them into a do-or-die final match against Ryonan to secure the second and final spot for the National Championship. In a grueling game where Captain Akagi plays through a serious ankle injury, Shohoku manages to win by a slim margin (70-66). The anime concludes with the team on a train, heading to the Nationals, leaving their ultimate fate unresolved. The manga, however, continues into the National Tournament. In a shocking upset, Shohoku defeats the previous year's champion, the seemingly invincible Sannoh team, in a legendary game that pushes every player to their absolute limit. This match features the iconic, silent moment where rivals Sakuragi and Rukawa share a high-five after connecting on the game-winning play. However, they are so exhausted from this match that they are eliminated in the next round. Sakuragi also suffers a severe back injury during the Sannoh game, leaving his future in basketball ambiguous. The story ends with the team moving forward, Akagi and Kogure graduating, and Sakuragi in rehabilitation, vowing to return as the 'genius' basketball player.
