クラウディウス

Dressed in modern sports clothing, the mischievous, childish Claudius is agile, but rash in his decisions. He is the master of the grimoire Celaeno Fragments (セラエノ断章 Seraeno Danshō) and controls the Deus Machina Lord Byakhee. [From Wikipedia.] In Kishin Hishou Demonbane, Claudius and the rest of Anticross from Zanma Taisei/Kishin Houkou were brought back by Another Blood as nightmare for her "story". The real Claudius as well as entire Anticross and Black Lodge has been erased from history, after the events of Al Azif's route.
