Description
Ikuko Onabuta is a central figure in the Nukitashi series, first appearing as a prominent supporting character and later taking on the role of a main heroine. She is a second-year student at Mizunotsuki Academy, where she holds the elite rank of Captain of the First Squad, known as the Strike Force, within the school’s disciplinary body, the SS. Her identification number is A-1, and she is recognized as one of the "Big Three" strongest members of the SS organization. Standing at 159 centimeters tall with measurements of 85-60-80, she has a distinctive appearance marked by pale skin, light blue eyes, and light blue hair styled in a short bob with inward curls at the ends, which she accessorizes with a black headband. She also has two small red heart tattoos on her shoulder.
Ikuko possesses a chaotic and battle-hungry personality. She is openly lewd, insatiable, and cannot tolerate anyone she perceives as being stronger than herself. She thinks about sex most of the time but is selective about her partners and has been scolded for being picky. Despite her wild and seemingly carefree nature, she is quite socially perceptive and often takes care of those around her within the SS. While naturally brilliant, she is not quite as academically gifted as some of her peers, such as Tōka Reizeiin, and she has a tendency to slack off when possible, contrasting with her otherwise reliable and capable demeanor. She has a sensitive side and feels insecure about her naturally curly hair, hating when people touch it.
Her personal history is marked by tragedy. Hailing from Nagasaki, she was born into a prestigious family that traditionally only taught swordsmanship to male heirs. Initially raised as an ordinary girl, her life changed drastically after the death of her mother during a pregnancy that also resulted in the loss of a younger brother. Following this, she was raised as a boy by her father and grandfather, undergoing brutal and rigorous training. Her only escape from this harsh environment was masturbation, which her father severely punished whenever he caught her. Eventually, an infectious disease killed her father and grandfather, though Ikuko survived after being taken to a hospital. She became an orphan and was subsequently invited to study at Seiran Island, where she found a new home and was able to express her femininity.
In the story of Nukitashi, Ikuko is initially an antagonist pursuing the rebel group NLNS. She confronts the protagonist, Junnosuke Tachibana, whom she suspects of being a rebel. Although she manages to capture him, she becomes confused and loses her memory of the encounter after Junnosuke uses his sexual techniques on her. However, unlike others who forgot, she retains a subconscious fixation on him, instinctively seeking him out and eventually nicknaming him "Darling." In the Misaki Hotori route, she is one of the few members of the SS who resists brainwashing from a criminal organization due to her prior sexual experience with Junnosuke, which was of a higher quality than the methods used to control the others. This leads to her expulsion from the SS, and with nowhere else to go, she joins the NLNS, having developed genuine feelings for Junnosuke.
In Nukitashi 2, Ikuko becomes a main heroine. The story transports her, Junnosuke, Tōka Reizeiin, and Rei Tadasugawa to a parallel world where she is part of a leadership group called the SS Big Four. After being expelled from the SS in that world as well, she helps form a new NLNS called the Love Dick Brothers. Her individual route explores her past in greater depth, revealing the full extent of her family tragedy. During this route, she and Junnosuke develop a deeper relationship, eventually becoming official lovers. In some future scenarios, she becomes a successful content creator and social media celebrity on Seiran Island, and in one epilogue, she is shown expecting a child with Junnosuke six years later.
As a combatant, Ikuko is considered one of the strongest fighters in direct combat on Seiran Island. Her martial arts prowess comes from years of harsh training in her family's style, rather than from natural talent alone. She always carries a katana with a reversed blade, designed for restraint rather than lethal injury, though her true specialty is close-quarters combat, particularly grappling techniques. When pushed to her limits, she can use stimulants and a gag ball to enter a berserker state, becoming even more powerful and losing her rationality. Despite her effectiveness in battle, her fighting style makes cooperation with allies difficult, so she typically operates alone.
