Pirachu is villian in Hyperdimension Neptunia Mk-2, and self proclaimed mascot of his people, whoever they are.
When the group first encounters Pirachu he is wounded and Compa insists on healing his wounds. Upon awakening, Pirachu instantly became smitten with Compa and professes his love and reveals he is one of Arfoire's followers. Compa calls him the enemy and refuses his affection, so he constantly follows the group around challenging them for Compa's affection.
