Neko, a human Strain wielding reality-altering powers, emerged from a childhood scarred by the Kagutsu Crater disaster. Surviving at age two due to her parents’ sacrifice, the incident erased her memories and left her with mismatched eyes—green on the left, light blue on the right. Unconsciously manipulating a grieving couple into believing she was their lost daughter, her fabricated reality collapsed when they reclaimed awareness of their son’s death, branding her a “monster” before abandoning her.

Adopting the name “Neko” from a beloved storybook character, she embraced a stray cat’s existence to evade human bonds. Her feline guise boasts light pink fur and a red collar with a golden bell. Lingering around Ashinaka High School, she observed pivotal moments like Mishina’s confession to Kukuri Yukizome before encountering Yashiro Isana, who plummeted through the gym roof. To shield him, she rewrote memories across the school, crafting a fabricated history that named him “Yashiro” and wove herself into his past.

Her personality dances between mischievous whimsy and raw vulnerability. Playfully defiant, she clashes with Kuroh Yatogami’s strictness, masking deep-seated fears of abandonment. These insecurities fuel her fierce attachment to Yashiro, whom she clings to as her sole emotional anchor. She prioritizes his safety instinctively, physically latching onto him under threat and resisting revelations about his true identity to avoid separation.

Beyond memory alteration, her powers distort sensory reality, enabling tactical advantages in conflicts. She shields allies and confounds foes, aiding Kuroh in defending Anna Kushina from the Green Clan in *Missing Kings*. Though prone to downplaying peril, her loyalty drives relentless searches for Yashiro after his disappearance, pushing her to ally with former enemies—a testament to her evolving trust.

Her journey reveals a fragile reconciliation with humanity. Initially rejecting “Miyabi Ameno,” a name tied to the couple’s dead son, she later acknowledges this buried past without surrendering her chosen identity. By *Missing Kings*, she evolves from isolation to active engagement in clan struggles, balancing cheeky antics with tearful pleas to reunite with Yashiro.

Post-Ashinaka Incident, her appearance shifts to a pink dress, thigh-high socks, and Yashiro’s parasol—a tactile reminder of their bond. While sporadically wearing Ashinaka’s uniform, she often opts for minimal attire, flouting conventions. Her growth crystallizes in empathetic acts: comforting Anna and bolstering Kuroh during their quest, cementing her role as both guardian and unifier among fractured factions.
