Bishop is the only priest in an old church, and has apparently known Haine for a long time. He is supposedly blind claiming he can "see" using his other senses. He has a Gothic-Lolita fetish and dresses Nill in the fashion. Despite his severe handicap, Bishop has been shown to be a swordsman of remarkable skill; having crossed swords with Freuling on even grounds and living to tell the tale. Haine once describes him as the church's "fierce guardian". His real name is Ernest Rammsteiner, and is the "lost number one" (the first Cerberus). He is another modified person with a collar like Haine's.
His last name is a tribute to the band Rammstein.
