Haven't You Heard? I'm Sakamoto

Sakamoto, a stylish and composed high school student, becomes the target of three classmates—Acchan, Mario, and Kenken—who repeatedly attempt to bully him, only to fail each time. Frustrated by their failed efforts, the trio decides to take more drastic action against him.

Sakamoto witnesses his classmate Kubota being extorted by bullies and offers to help, though he has no money to give. Instead, he devises a clever plan to assist Kubota in a different way.

Maruyama, a second-year student known for his delinquent behavior, recruits first-years to run his errands. Sakamoto joins the group and proves to be an obedient and capable errand boy, which pleases Maruyama. As time passes, Maruyama becomes less involved in giving orders and instead expects Sakamoto to serve him without being told.

Sakamoto is known for his punctuality, artistic talent, culinary skills, and inventive abilities, but his sudden and mysterious disappearances raise questions.

Sakamoto faces a challenge from Hayabusa, the second-year leader of the delinquents, in a test of strength and skill. After the confrontation, Sakamoto falls ill with a cold.

Sakamoto's magnetic personality continues to captivate a wide range of people, from bullies to students. His charm even extends to the supernatural, as he effortlessly wins over a mysterious pale ghost with long black hair.

Acchan's gang faces a challenge in accessing the over-18 video section until Sakamoto unexpectedly helps them. Later, Sera attempts to challenge Sakamoto during a school sports event.

Sakamoto's class prepares a display for the school festival, but their efforts are disrupted when a former delinquent returns to the school and challenges Sakamoto to a game he may not be able to avoid.

The students in Sakamoto's class reflect on the circumstances that brought them together, sharing personal memories of their first encounters with him, while Kubota, despite falling ill with a cold, decides to attend school as usual.

Sakamoto finds himself at a mixer, an unfamiliar social setting that leaves him out of his element. Meanwhile, Hayabusa also faces a new and challenging situation, though he has company as he navigates it.

Acchan eagerly introduces Sakamoto to snow play, but his enthusiasm leads to a miscalculation that Fukase observes and later exploits.

As Sakamoto delivers a farewell speech at graduation, he is suddenly attacked by Acchan. Meanwhile, Fukase appears determined to remain at the school indefinitely, though this latest incident may mark the end of his plans.
