This is a goofy magical girl revenge comedy where the actual heroes get immediately upstaged by their jealous girlfriends transforming into an angrier, more competent team. The whole thing runs on pure absurdist energy, ridiculous character names, paper-thin excuses for transformation sequences, mecha that exist mostly to justify why these three women keep showing up to fight their own boyfriends. It knows exactly what it is and never pretends otherwise.

Lamune and Da Cider set out for Puff-Puff Palace to rescue the Mountain Duo, Gold Mountain and Silver Mountain, a pair of beautiful and barely dressed maidens. Milk and Leska are furious about it. Together with a confused and unwilling Cocoa, they transform into Seinaru Milky, Seinaru Cacao and Seinaru Lemon, a spoof of Sailor Moon's heroines. The three then go after their would-be boyfriends to get their revenge. The story runs across three OVA episodes and mixes comedy, fantasy, adventure and mecha.
