Sumire Takahana is a seemingly normal school girl cursed with the ability to see malevolent ghosts known as "Viruses." Her life hits a crossroads after a run-in with Lucia, a gothic lolita-clad monster killer-for-hire. Not content to stay on the sidelines while these Viruses prey on the weak, Sumire decides to join forces with the mysterious, eyepatch-wearing Lucia to hunt down the Viruses before they can hurt anyone else.
As Venus Vangard squares off against Sonoka's evil minions, Sumire's berserker powers spiral out of control... and it's Lucia who's caught in the middle!
This omnibus collects volumes 4-6 of Venus Versus Virus.
