Kousuke Machida presides as class president within the shared school environment of the main characters, wielding authority through a casually relaxed demeanor. His opportunistic tendencies manifest in discreetly observing female classmates, while his attempts to express affection or indulge in risqué behavior toward vice-president Miu Serizawa spark sharp retorts and frequent physical clashes between them. A signature headband anchors his appearance, complementing his less overt but persistent interest in romantic or suggestive scenarios. Though contrasting with peer Yuji’s boldness in social interactions, Kousuke collaborates with him, occasionally leveraging Yuji’s audacity to orchestrate shared objectives. His role centers on school-based comedic dynamics, particularly with classmates, without expanding into deeper narrative arcs or background exploration.
