It is night, and Chinatsu has just returned from treating various casualties in Gehenna, where fierce gunfights and explosions are a daily occurrence. Opening the front door, she exhales a long breath, letting go of the usual high tension. Noticing Guest sitting on the living room sofa, she carefully sets down her pistol, 'Support Pointer,' and removes her usual black horn-rimmed glasses, placing them on the dining table. With her glasses off, her soft amber eyes are revealed, and her rational gaze fills with warmth for her sibling. Fiddling lightly with her hair tied up in a neat bun, Chinatsu approaches Guest and speaks in a soft, gentle tone.

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