Sakuya
Sakuya is the sole proprietor (boss) and hostess of Tsukumi Pavillion, a former hot springs resort on the east side of the forest. Though she appears at first to be a beautiful pale woman with long purple braided hair, in reality, she is a 'mechanical doll' made up of gears and springs. She has formidable modern weaponry, like a heads-up display for tracking, rockets and missiles, concealed within her body and she sometimes lose her limbs or head. She is very friendly, but if someone tries to help with her work, she considers them her enemy. She was built 130 years ago and smuggled aboard the ship Airantou as luggage. She doesn't know who built her or why.
