Kimi Nishino

She is a young woman with short brown hair worn in a hime-cut, one side tucked behind her ear while a single long strand trails down the other, above brown eyes. Dressed like the everyday college student she is, she wears a pair of bracelets that match the ones her partner Nishiki keeps on as a sign of their bond.

Composed and diligent, she is fiercely loyal to Nishiki, who unknowingly pulled her out of grief after an accident claimed her family. She guards the secret of his nature and her ties to other ghouls carefully, aware that aiding humanity's enemies carries heavier consequences than shielding a human criminal. Her resolve runs deep: she genuinely wants a world where the two species live side by side, and she throws herself into Akihiro Kanou's research to reach it, even though his methods trouble her.

Her parents and younger brother died in an accident, and Nishiki entered her life around that time, drawing her out of her loneliness. She later found him gravely injured after a clash with Kaneki and learned he was a ghoul; when he lashed out, too weakened to overpower even a human, she let him bite flesh from her shoulder, leaving a lasting scar. Mistaking Kaneki for the ghoul stalking Nishiki, she once attacked him before the two struck a bargain of mutual silence.

Seeking help for Nishiki's slow-healing wounds, she was seized by Shuu Tsukiyama and held captive in a chapel, freed only when Touka arrived and beat him, prompting Kimi to marvel at the beauty of Touka's kagune. Years on she works as an assistant in Kanou's ghoul experiments. After Kanou takes his own life, she and the other aides bring everything they know to the CCG to support the effort against Dragon, and she reunites with Nishiki for good. Her research ultimately helps create a synthetic food ghouls can stomach, chasing her twin dreams of easing their hunger and one day taking the Nishio name.
