七海 やちる

A university student visiting Akatsuki town when the Koushin Disaster strikes. Nao saves her and Kamori when he encounters them by chance after leaving the ruined underground passageways.

Although supremely confident in her appearance and abilities, she's really a klutz who panics easily and likes to show off her achievements to her fellow survivors, no matter how minor they might be.

After escaping Akatsuki town, she leverages her fame as a Disaster Zone Survivor by working in the entertainment industry. Her duties include filming variety shows and commercials for the local media outlets in New Akatsuki Town.

Her Baroque power is the manipulation of sound. She can manifest a parrot (which is a talking outlet of her subconscious self) and direct it at targets with considerable sonic force. She can confuse opponents by creating decoy noises and silencing her own.

The only heroine who survives all three routes relatively unscathed. She serves as Nao's love interest in the "normal" end. Despite her clumsiness and propensity to panic under pressure, she eventually matures and overcomes her opponents in the duels she is forced into on her route.
