Paimon

King Paimon (His cherished title), Alexei (First name given to him by Leo. They're very fond of this name, it reminds them of Alexander the Great), Rogozhin (Another name given to him by Leo. Thinks the name is obnoxious so it's urged by him not to use).

They're very confident in themselves, yet wise enough to check themselves once in a while. Tend to speak with a loud voice which is considerably deeper than Leo's usual tone. Also very secretive, only choosing to tell people certain bits of his plans but not letting them in on the whole story.

Motivated to live in quiet victory. To successfully hide themselves among modern society to avoid the responsibility of serving a human. In their current situation, they hope to help Leo live a fulfilling life, to rise above everybody else and achieve fame, while being inconspicuous enough to attract the attention of fellow demons.

They're an absolute perfectionist. If without help, Paimon's schemes fall flat. This is because they're fixated on details, trying to make it as perfect as possible while failing to see the bigger picture.

Hates the concept of demons serving humans with a passion. They also strongly dislike anything that reminds them of god, like water.
