Shinobu Sensui

Shinobu Sensui (仙水 忍, Sensui Shinobu?), also known as Black Angel, is a former Underworld Detective and the antagonist during the Sensui arc. Sensui was a prodigy aura user and demon hunter from an early age. He was recruited by Koenma as Underworld detective and worked tirelessly. His view of demons is changed when he met Itsuki, who plead for Sensui to spare him for one day so he could see the finale of his favorite television show. Itsuki ended up working as Sensui's partner, gradually widening his black and white views on justice. During a routine case Sensui came upon an early hideout of the Black Black Club, a room where humans were torturing demons, bathing in their blood, and committing other evil acts. Seeing the cruelty of those he was sworn to protect Sensui went mad and killed everyone there. He soon disappeared, taking with him the Black Chapter, a video tape kept in the vaults of the underworld containing footage of the most evil deeds of humanity. Sensui waited until a new Underworld detective was revealed before coming out of hiding, springing his plan to judge the human race. During his years in hiding, Sensui created seven alternate personalities to deal with the stresses on his mind. Only four of his alternate personalities are ever revealed and they are as follows:

• Minoru - a charismatic speaker who was in control during the beginning of the Sensui arc.
• Kazuya - a sadistic killer who takes over as Yusuke gets the upper hand fighting Minoru.
• Naru - a female personality spoken of by Itsuki who writes poetry.
• Shinobu - the leader and strongest of his personalities.

Sensui is a master of Lightning Kickboxing (裂蹴拳, Resshūken?, lit. "Fissure Kick Fist"), an elegant fighting style that mixes fluid arm blocks with powerful kicks and is said to be only available to those who have already mastered all forms of martial arts. Sensui also wields Holy Aura (聖光気, Seikōki?, Saint Light Energy), a special type of energy that is said to be the purest of all auras, mastered only after 40 years of training, though Sensui mastered it in just over six years with his seven different personalities. In the anime television series, Sensui is voiced by Rokurō Naya and Akira Ishida (Younger) in Japanese and Robert McCollum in English.
