Sadahiro Mibu (壬生貞比呂 also nicknamed Auditor ) is Akira's contracted monk who was exiled from the Kōgon Sect for 5 years and the only contracted monk who has the authority to kill human beings. He is also the former friend of Keisei and Akasha during their early years of training.
In the anime adaptation, Sadahiro initially appeared as Ouri's manager at the Cafe Parthenon. He is often seen acting lazy who wears causal jeans, a dirty t-shirt, and smoking a cigarette. They both work undercover to keep an eye on Ouri and Keisei. He is an expert of Zadan techniques. He's specialty is using a dagger to cut down the enemy and his support power is to empower his Shikabane Hime's firing capability at any range. He also has the misfortune of getting clobbered by Akira whenever he acts idiotically.
