Description
Orphaned as a child during an Other attack, Kasane Randall was adopted by the owners of Randall Industries, who treated her harshly and never accepted her. Only her adoptive sister, Naomi Randall, showed Kasane genuine kindness, gifting her a handmade hair ornament that became Kasane's most treasured possession and a symbol of their bond.
Kasane presents a cool, pragmatic, and emotionally distant demeanor to strangers, often appearing indifferent or unaware of social cues—a guarded personality stemming from childhood neglect and trauma. She reserved her kind and caring nature for those she deeply trusted, primarily Naomi. Psychological analyses noted traits of strategic thinking, analytical problem-solving, and a preference for privacy and intellectual independence.
Physically, Kasane possesses long gray hair and red eyes. She typically wears a Shinobi variant of the OSF uniform consisting of a shoulderless top, gray leggings, and a hood employed during Brain Drive activation, her appearance always featuring the distinctive hairclip from Naomi.
Her primary combat ability is Psychokinesis, enabling manipulation of environmental objects for offense and defense. She wields specialized collapsible throwing knives called Arrowroot Leaves, which split into multiple blades mid-combat. Her combat style emphasizes aerial maneuvers, area-of-effect attacks, and synergistic use of OSF systems like the Struggle Arms System (SAS) to temporarily borrow psychic powers from allies. She utilizes high-risk abilities such as Brain Drive, enhancing speed and psychokinesis, and Brain Field, creating a psychokinesis-dominant space disabling enemy psychic abilities.
Scouted by the Other Suppression Force (OSF) at age 12 due to exceptional psionic potential, Kasane graduated top of her class, joining the Kyoka Platoon. Early missions involved defending Suoh City alongside Naomi. During an operation in an abandoned subway, Naomi sacrificed herself to protect Kasane from a bullet, triggering Naomi's transformation into an Other. This event propelled Kasane to investigate government conspiracies involving artificial Others.
Her investigation led to confrontations with OSF traitors like Karen and encounters with the Design Children—clones created by the Togetsu organization. Kasane discovered her own origin as a Design Child, genetically engineered from Togetsu's founder, and learned her biological mother was Wakana Sumeragi, making Yuito Sumeragi her brother. Kasane also experienced recurring dreams about "red strings," later revealed as conduits for time manipulation.
To prevent a dystopian future where Yuito's powers destabilized the Kunad Gate, causing global devastation, Kasane initially attempted to kill him under future Yuito's directive. Branded a traitor, she later allied with Yuito upon revealing the truth. They confronted Karen, who sought to alter history to save Alice. Kasane traveled back in time 11 years to rescue young Yuito and Wakana from an attack, bringing Wakana to the present to help dismantle the Kunad Gate. Wakana ultimately sacrificed herself to sever the red strings.
In the aftermath, Kasane joined the Lunar Surface Survey team, continuing her service with the OSF while carrying forward the memories of Naomi and Wakana.
