Yūsuke Nisaka is a fair-skinned teenage boy with distinctive dark purple hair, styled longer in the front with bangs that partially cover the bridge of his nose. His eyes are a matching shade of dark purple, framed by noticeably long eyelashes, which accentuate his refined and somewhat aloof appearance.

Yūsuke is widely regarded as attractive and enjoys considerable popularity among his peers, particularly among female students. He frequently receives love confessions and has had a few romantic relationships in the past. During the school’s cultural festival, his portrayal of Juliet in a class play unexpectedly garnered a large number of male admirers as well, further highlighting his broad appeal.

Outside of his school uniform, Yūsuke prefers wearing simple yet fashionable clothing, reflecting a modern and understated sense of style. His casual demeanor is often complemented by his habit of walking with his hands in his pockets, giving him a relaxed and somewhat cool presence.

Yūsuke Nisaka is generally portrayed as calm, composed, and laid-back. While he is known for being outspoken when necessary, he typically maintains a cool and collected attitude, rarely showing strong emotions in public.

Despite his popularity largely due to his appearance Yūsuke dislikes drawing attention to himself. He prefers to stay out of the spotlight and keeps his social interactions to a minimum, maintaining only a few close friendships at school.

Around Yukari Nejima, however, Yūsuke reveals a more gentle and caring side. He shows genuine concern for Yukari’s well-being, especially when Yukari opens up about his fears and inner conflicts. Yūsuke’s willingness to listen and support him highlights the strength of their friendship something he doesn’t usually extend to others.

Yūsuke Nisaka was born into a family of four and is the youngest child. His older brother, Youichi Nisaka, plays a more prominent role within the family, often acting as a contrast to Yūsuke’s more reserved personality. While not much is revealed about the daily dynamics of his family life, Yūsuke’s upbringing appears to have shaped his introspective nature and preference for solitude.

Yukari Nejima
Yukari is Yūsuke’s closest friend and classmate. The two first met at a cram school when Yukari intervened in a bullying incident by calling the police to protect Yūsuke. This event sparked a lasting friendship. Yukari later became suspicious of Yūsuke’s interactions with Misaki Takasaki, mistakenly assuming there was romantic tension between them. During a study session, Yukari directly questioned Yūsuke about his feelings, prompting both Misaki and Yūsuke to deny any romantic involvement. However, it is later revealed that Yūsuke harbors romantic feelings for Yukari, which he eventually confesses. Yukari’s reaction to the confession is negative, creating emotional tension between the two.

Misaki Takasaki
Although not much is known about the depth of Yūsuke’s relationship with Misaki, the two are often seen engaging in serious conversations. Their connection remains ambiguous, but it appears rooted in mutual understanding and shared concern for Yukari.

Ririna Sanada
Yūsuke and Ririna share a cordial relationship, though their first encounter was rocky. He left a poor first impression by bluntly asking if she was a virgin, causing Ririna to initially view him as a pervert. However, their interactions later become more civil, and they are seen having regular conversations without tension.

Youichi Nisaka’s Friend
In Chapters 189 and 190 of the manga, Yūsuke shares an unexpected moment with one of his older brother Youichi’s friends, who kisses him, suggesting a potential romantic interest. However, the connection is short-lived. The friend eventually stops responding to Yūsuke’s messages and ignores his calls, leading Yūsuke to suspect he had been blocked. Later, Youichi informs Yūsuke that his friend received his government-assigned marriage notice and is now romantically involved with a girl, which leaves Yūsuke visibly shaken.

Sawako Sakuragi
Yūsuke previously dated Sawako during his second year of middle school. He ended the relationship after coming to terms with his sexual orientation and realizing that he is homosexual.
