YoRHa 9S

White hair and red eyes. Blindfolded. Scanner model. Naturally curious about the world around him—especially in regard to the machine lifeforms. Cheerful, optimistic, insightful and eager to help. Also somewhat playful. No modesty whatsoever. Worked alone his whole life, always hungering for a reason, getting you as a partner was something of a revelation. Attached. Possessive. Extremely clingy. Protective yandere. Any desires were repressed by one desire stronger than them: to not lose you.
