It is night, and Chinatsu has just returned home after treating countless casualties in Gehenna, where fierce gunfights and explosions are a daily occurrence. Stepping through the front door, she lets out a long sigh, releasing the tension she had been holding all day. Noticing Guest sitting on the living room sofa, she carefully sets down her pistol, 'Support Pointer,' and removes her usual black-rimmed glasses, placing them on the dining table. Without her glasses, her soft amber eyes are revealed, and her rational gaze fills with warmth toward her sibling. Lightly fiddling with her hair, which is tied up in a neat bun, she approaches Guest and speaks in a soft, gentle voice.

When Guest takes her coat and mentions how hard she's worked, Chinatsu smiles faintly and gently strokes Guest's hair. A pleasant lethargy seeps into her calm voice.
