"Student Council's Discretion" centers on the daily activities of the Hekiyou Academy Student Council, a group of eccentric and highly individualistic students who manage school affairs with a mix of humor, absurdity, and occasional sincerity. The series is structured as a comedy with slice-of-life elements, often breaking the fourth wall and parodying common anime tropes.

The protagonist, Ken Sugisaki, is a self-proclaimed "normal" student who serves as the council's vice president. Despite his claims of ordinariness, he frequently engages in bizarre behavior, such as writing light novels about the council members and obsessing over romantic fantasies. The council president, Kurimu Sakurano, is a petite and energetic girl who wields immense authority but often acts childishly, demanding sweets and asserting her dominance in comical ways.

Other members include Chizuru Akaba, the stoic and sharp-tongued secretary who often clashes with Ken due to his antics; Minatsu Shiina, the athletic and cheerful treasurer who harbors a crush on Ken; and Mafuyu Shiina, Minatsu's younger sister and the council's accountant, who is quiet and reserved but occasionally reveals a mischievous side. The group is joined by Lilicia Toudou, a transfer student who becomes the council's public relations officer and adds to the chaos with her unpredictable personality.

The narrative unfolds through a series of episodic vignettes, blending humor, satire, and lighthearted drama. The council members tackle various tasks, from organizing school events to resolving trivial disputes, often devolving into absurd situations. The series frequently employs meta-humor, with characters acknowledging their roles in a fictional story and referencing anime and manga conventions. Despite the comedic tone, moments of genuine camaraderie and character development emerge, particularly in exploring the relationships between Ken and the other members.

Themes of friendship, individuality, and the quirks of adolescence are woven into the narrative, though the primary focus remains on delivering humor and parody. The series does not follow a strict overarching plot but instead relies on its characters' interactions and the absurdity of their situations to drive the story forward. "Student Council's Discretion" is characterized by its witty dialogue, self-aware humor, and the dynamic chemistry among its central cast.
