Sarina Tougou is the composed assistant director and general analyst of Kura’s Wellside division, operating under Funetaro Momoki. Joining six months before the series’ pivotal events, she plays a crucial role in the Mizuhanome System by dissecting id wells and transmitting vital data to field investigators. Her expertise extends into navigating the unconscious realms of killers, where her unflappable poise ensures survival under extreme duress.

She possesses striking green eyes and long red hair often swept into a loose bun fastened with dark turquoise barrettes, accentuated by a subtle mole beneath her left eye. Professionally attired in a gray suit over a dark blue shirt, she adopts understated elegance for formal occasions with a white pearl necklace and black lapel pin.

Renowned for her stoic demeanor, Sarina reveals fleeting warmth through rare smiles, particularly reserved for colleague Koharu Hondomachi—the sole recipient of her informal first-name address. Within the Wellside team, her discreet romance with Momoki circulates as a quietly acknowledged truth, never hindering their professional synergy.
