My friend has a headcanon about how Pompompurin fights. It revolves around LZL hurling Big Dog in the face of whatever boss they're up against, where Big Dog then, uhh, farts in their face a la Iggy from JJBA.

Archangels v1 and Archangels v2 are actually stereotypical frat boys and sorority girls. Though Gabriel and Famiel are in a relationship, Famiel likes to hangout a lot with the foreign Sachi Bros.
