Sumimasen

Two anime-style female characters stand side-by-side in a school hallway; the character on the left, with long orange hair and white horns, has her eyes closed and a sad expression, while the character on the right, with long brown hair and green eyes, looks at her with a concerned expression, as text in a dialogue box below the left character reads "Chihaya: Hmm... sorry... I don't understand."
