Description
Ozu is a student at Kyoto University and a classmate of the unnamed protagonist, enrolled in the Department of Electrical and Electronic Engineering in the Faculty of Engineering. He is a young man of roughly twenty years with a pale, somewhat otherworldly appearance that is often compared to a mochi rice cake, and his expressive, mischievous features give him a distinctly impish look. He is frequently seen at the Neko Ramen food stall, and his private life remains largely mysterious; the protagonist only rarely catches glimpses of what he does outside their time together. Ozu describes himself as someone bound to the protagonist by a black thread of fate, a phrase that captures the strange, inescapable closeness between them.

In terms of personality, Ozu is cunning, quick-witted, spontaneous, and deeply sardonic. He takes visible pleasure in causing chaos, meddling in other people's romantic affairs, and pulling the protagonist into elaborate, morally ambiguous schemes. His dark sense of humor and enigmatic manner make him difficult to read, and he often seems to know more than he reveals. Beneath his carefree and somewhat nihilistic attitude, he holds a firm belief in experiencing life fully on his own terms, even when that means disregarding social conventions or inviting disaster. He is manipulative and gleefully provocative, yet his actions are not purely destructive; they are repeatedly shown to be guided by his own peculiar sense of loyalty.

Ozu's motivations center on enjoying life to the fullest and dragging the protagonist along with him. He rejects the idea of a safe, idealized existence and instead pushes others toward honest, unpolished experience, even when the results are humiliating or absurd. His schemes are often the direct cause of the protagonist's misfortunes, but they also serve to shake the protagonist out of passivity and self-deception. In this way, Ozu acts as both a catalyst for trouble and a strange source of perspective, challenging the protagonist's assumptions about what a meaningful youth should look like.

Within the story, Ozu appears as a constant presence across every version of events. He functions as the protagonist's closest friend, rival, and partner in mischief, and in practical terms he is the force that repeatedly derails any attempt at a peaceful or conventional campus life. His role is that of a foil: while the protagonist endlessly analyzes his choices and dreams of a perfect existence, Ozu simply acts, often impulsively and without concern for consequences. Their friendship is defined by mutual irritation and a strange, unspoken trust, and it is through this bond that the protagonist is eventually led to recognize that happiness is not found in flawless circumstances but in embracing the imperfect, messy present.

Ozu's most defining relationship is with the protagonist, whom he treats as a partner in crime and genuinely respects despite his teasing and sabotage. He is also a devoted student of the older Higuchi, whom he addresses with reverence and regards as a master of sorts. With Akashi, he is openly wary and views her as a potential threat to his influence over the protagonist, though his attitude toward her never becomes truly malicious. Notably, Akashi is one of the few people capable of standing up to Ozu and deflating his schemes, and their clashes are a recurring source of friction.

Although Ozu remains a chaotic force for most of the series, his character gains considerable depth as the story unfolds. In the final stretch, it becomes clear that his disruptive actions have often been driven by a genuine, if unconventional, loyalty, and a vulnerable side emerges when his own romantic aspirations and personal struggles are brought into the open. He evolves from a simple troublemaker into a figure whose antics carry emotional weight, revealing lingering uncertainties beneath his confident exterior.

Ozu has no supernatural powers or combat abilities. His most notable skills lie in his sharp social instincts: he is adept at reading and manipulating situations, engineering elaborate pranks and dubious ventures, and persuading others to follow him into questionable undertakings. He also has a talent for philosophical provocation, using teasing and ironic remarks to push his friends toward uncomfortable but valuable self-reflection, which ultimately makes him far more than the mere instigator he first appears to be.
