Pheromone Lip acts as a key subordinate to Don Genoci within the VS Knight Lamune & 40 Fire series. She forms a comic relief villain duo with Narcist Dandy, serving together as priests in the Kira Kira temple under their master's command. Their missions involve obstructing the hero Lamunade and advancing Don Genoci's objectives.

Exposure to Aburahm's corrupting power during the Black Lamunes arc transforms Pheromone Lip into Black Lip, shifting her allegiance and intensifying her threat. After her ultimate defeat in this corrupted state, she reverts but undergoes another change, emerging as Nipple Sherbet. In this new identity, she joins Don Genoci's entourage when he reveals his true form as a grand priest.

Pheromone Lip's story concludes differently across adaptations. The manga depicts her sacrificing herself alongside Dandy to seal away Don Genoci's evil power.
