Description
Hikaru Onigashima is the older twin brother of Hinako Nakayama, separated from her at birth. He was raised as the son of the Onigashima yakuza family head, while his sister grew up in an orphanage unaware of her lineage.
He has short pink hair and garnet eyes. His personality is selfish and moody, often expressed through a girly and cute attitude. He is pushy and needy, though his actions are typically well-intentioned. A defining trait is his pronounced monophobia, a fear of being alone. He is lively and possesses a significant obsession with the singer Mirako Yuta, who attends the same school as his sister.
Unwilling to comply with his father's demand that he enroll at the all-boys Shishiku Academy and become its top bancho, he devised a plan to have his sister take his place. He engineered a situation to blackmail her, falsely claiming she seriously injured him and threatening to demand payment for medical expenses if she refused to impersonate him. Following the switch, he adopted a feminine presentation, attending her all-girls school, Kotobuki Academy, in her place while wearing her uniform and a ribbon hair accessory, now depicted with long pink hair. His sister moved into his apartment alongside his caretaker, Haruo Sakaguchi, the only person aware of the switch who works to cover for them. Hikaru is frequently disgusted by his caretaker's overzealous devotion.
His relationship with his half-brother, Houou Onigashima, is strained and hostile. Hikaru treats Houou poorly, which contrasts with Houou's desire for a fraternal bond. It was later revealed that their father had discarded Hinako at birth because, as a daughter, she was not seen as useful to the yakuza family, a fact that contributes to Hikaru's internal conflict and resentment toward his familial duties.
In the sequel, he remains enrolled at Kotobuki Academy. A new development occurs when the school announces its intention to become co-educational, planning to accept all the male students from Shishiku Academy, which faces demolition. This situation involves his school and the characters from Shishiku, though he primarily remains in his established role.
His character development is minimal, consistently maintaining his preference for a peaceful, non-confrontational life focused on pop culture and shopping over the violent ambitions expected of his yakuza heritage. His primary motivation remains avoiding the burdens of his birth family.
