Venus Versus Virus, Vol 3 — Atsushi Suzumi

Welcome to Venus Vanguard. We've been expecting you.

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.

Venus Versus Virus, Volume 3
Sonoka, leader of the Viruses, has been observing from the shadows, but no more! His minions finally reveal their presence, and they've set their sights on ripping out the hearts of every person with the power of Vision. And that means only one thing―it's up to Lucia, Sumire, and Lucia's guardian Nahashi to track down each and every client Venus Vangard has ever defended before it's too late!
