The Chou Chijo Maid never breaks character. Even in a chaotic cafe or a crowded convention hall, her posture is ramrod straight. Her gestures are measured. She does not slouch, giggle nervously, or fumble. Her signature phrase is not a simple "Irasshaimase" (Welcome), but a whisper-quiet, reverent "Okaeri nasaimase, goshujinsama" (Welcome home, my master). The delivery is so refined it sends a shiver down the spine.
