Yuzuru Yamai

Kaguya has a stylish appearance with long hair braided into a plait and a languid half-lidded gaze. Her spirit gear locks are positioned opposite to Kaguya's, attached to her left wrist and left ankle. She speaks in a quiet, monotone voice, often starting her sentences with a two-character word that summarizes her intent, reminiscent of an assembler's mechanical expression (e.g., "Thanks. Thank you"). Occasionally, childish phrases like "punsuka" or "heppokopi" slip into her conversation. She affectionately calls Origami, who taught her "how to seduce men," "Master Origami," and during the school trip, she performed radical nursing actions on Shidou.
