I'll (titled I'll Generation Basket in its French release) is a sports shōnen manga by artist Hiroyuki Asada. Its main plot concerns the life of a team of high school basketball players. It is focused on action scenes which depict the matches played by the team, but also puts emphasis on the interaction of characters outside of the courts. The art style is very clean and effective, showing movement as well as emotions well. The manga has been published in several countries of Asia, in France and in Italy.
Akane Tachibana is a freshman high school student who, despite his talent for basketball, decides to abandon sports clubs due to the pressure put on him by them. Once he arrives at Kouzu High, however, he meets the only other basketball player who has ever caught his eye on the courts and decides to join the team. The first match of the season is an exhibition game against the league's strongest team, Hyamazaki — the team that Hiiragi's father coaches and in which his older brother plays for. Hiiragi ends up playing in the second half of the game, and they seem to not be working well together on the court, losing the game, until unintentionally one of the senior players on the team challenges them to beat him. They join forces, inspiring the team to victory. Thus starts the story of a group of teenagers working to reach the top, fighting tooth and nail the entire way.
