カリグラ

A tall, powerful individual who hides his human face behind a skull mask, he is often seen alongside fellow Anticross member Claudius. Caligula has the grimoire Cthäat Aquadingen (水神クタアト Suijin Kutāto, lit. The Water God Cthäat) and controls the Deus Machina Kraken. 

.

In Kishin Hishou Demonbane, Caligula and the rest of Anticross from Zanma Taisei/Kishin Houkou were brought back by Another Blood as nightmare for her "story". The real Caligula as well as entire Anticross and Black Lodge has been erased from history, after the events of Al Azif's route./
