Oboro Daikyoh (朧 大凶, Oboro Daikyō) is a samurai ghost and the guardian ghost of Asakura Yohane. He is known as the Unhappiness-Bearer Vagabond Swordsman (そしてその持ち霊の不幸を呼ぶ流浪の剣士, Soshite sono Mochi Rei no Fukou wo Yobu Rurou no Kenshi).
Daikyoh was born and raised during the Meiji Restoration. He was once a noble samurai, but with the ban of katanas, he was forced into the army. Many of Daikyoh's fellow samurai also volunteered to join the Japanese Imperial Army.
One day while drinking, Daikyoh visited his former comrades who all pointed their weapons at him and in a drunken rage he attacked them, forcing them to gun him down.
This is the most basic of Yohane's abilities. He uses his umbrella as a substitute for Daikyoh's sword.
- Oboro Zangetsu (朧斬月,Haze Slaying Moon):
- Kyōsha (凶車, Bane Wheel): A powerful thrusting technique developed for closing the distance between the user and his opponent. According to Daikyoh, had he wielded his own sword against Hana, this technique would have been strong enough to blow a hole in his stomach.
