Sabitsuki is the 16-Year-Old protagonist of the game .flow. When prompted to leave her room she shakes her head, in a similar fashion to Madotsuki, leading many to believe she is a hikikomori or quarantined. The dreams she experiences tend to be dark and violent (HL2 Beta-like), suggesting her personality or past experiences are the same. She wears a dark blue-ish purple/indigo top with a turtleneck collar and no sleeves. Her sister is Harumi.
