Garterbelt is the reverend of Daten City and the mentor of the Anarchy sisters, Panty and Stocking, as well as the Daemon sisters, Scanty and Kneesocks.

[ Background ]

Garterbelt has a very checkered past. In "Once Upon a Time in Garterbelt", it is revealed that Garterbelt used to be a gangster, who performed various crimes, including assault and drug dealing. He eventually became the greatest crime lord in his town, but was gunned down in his own office.

Soon after, he ended up in Heaven, where he was given an as-of-yet undisclosed mission by Judgement. When he refused to take it, he was cursed with immortality and sent to the beginning of time, forced to live through the creation of the world as it is today, going through biblical events such as Adam and Eve (in which he ate the apple), Noah's ark, etc. Eventually, Garterbelt finally realized that his own suffering would lead to true happiness. He then retained his immortality, became a priest and was given the task to supervise two angels, Panty and Stocking. Due to being immortal, Garterbelt explodes in a manner similar to ghosts whenever he is killed, only to reassemble himself moments later. After the incident, due to the Ghosts in Hell got loose and at the request of Satan, Garterbelt was given the task to supervise the Daemon sisters, Scanty and Kneesocks as well.
