Saint Peter is a young-looking male Angel, and the Gatekeeper of Heaven. He welcomes new arrivals into the realm, always standing guard at the Pearly Gates. Peter is a highly energetic and bubbly person, who seems to genuinely enjoy his job, and always sings high praises of Heaven as a whole.
Peter is on friendly speaking terms with the higher-ups of Heaven, such as Sera, the leader of the Seraphim, and Adam the First Man, the Giver of Names and the leader of the vicious Exorcists.
