Kyouhukou (恐怖公, きょうふこう) is an Area Guardian of the Black Capsule (黒棺, ブラック・カプセル) on the 2nd Floor of the Great Tomb of Nazarick.


Kyouhukou's appearance is that of a 30cm tall cockroach standing on its two legs and with its head facing forward. It wore a bright red cape decorated with luxurious golden threads around the edge and a cute little golden crown on top of its head. Grasped in its front leg was a scepter with a pure white gem embedded at the end.


Kyouhukou's personality displays a hint of nobility like his attire would suggest. He speaks politely and over all seems to think of himself as a noble gentleman.
