Black Label has always been glad to have Sayo Hitsugi's fearsome strength on their side, but as she rampages through Black Label's high security wards, they're starting to appreciate just how much! While Sagiri is prepared to stop her comrade by any means necessary, is Arashi on the same page...?

A new, unknown jet injector is lose in the city, sowing the seeds of chaos and death. The humans she infects turn into frothing, raving white-haired maniacs driven to torture and kill. And what's worse--anyone who comes into close contact with these monsters is liable to become one themselves. Tatara and Suzue are in trouble--will Black Label reach them in time!?

Mochizuki General Hospital boasts some of the most well-trained (and well-endowed) nurses in town. But though these ladies spend much of their day battling sickness, their after-hours are spent fighting a very different sort of disease...Under the leadership of the hospital chairman, a handful of staff members and local teenagers form a group of mercenary assassins, targeting the "cancers" of society and excising those individuals before their wickedness spreads.

As their adversary grows more aggressive, Black Label is forced to take drastic action. Bypassing the chaos of the streets above, the survivors are led through deep underground tunnels to the safety of Mochizuki Hospital-the heart of Black Label itself! Risking their organization's exposure may be the only way to save the city, but with Reika Togo's whereabouts and intentions still a mystery, the risk may be greater still...!

Black Label regroups and rushes to Mochizuki’s side, their progress inhibited by the last of Syringe’s goons. In their absence, Reika takes a moment to relish her victory and the revelation of Fiona’s true nature. Fiona and Mochizuki represent the key to unlocking D99—and unleashing a whole new wave of terror that will spread beyond the streets of Tobioka to the whole world!

The battle of Mikami Storm begins! The whole team of the Fujoshi clan has been waiting for this moment to change their destiny...Who will manage to make it through?

With Mikoto and Oriha still at the mercy of Syringe agents, Arashi reluctantly teams up with Chikage, and the two race to rescue their friends. So far, Chisa Yuki has maintained her innocent act in front of the other survivors, but the moment she turns bloodthirsty, Black Label won't be the only ones who suffer...

While Black Label is locked in a stalemate with Syringe, D breaks ranks to confront Arashi. Though Arashi is reluctant to let his personal grudge distract him from the larger disaster at hand, the threat against Kominato is too great to ignore. Arashi’s past and future priorities converge in this final confrontation with the terrorist D!!

Mikoto is crippled during an operation, but is saved at the last moment by the sudden appearance of the masked vigilante - "Fever." But rescue isn't on this black-clad beauty's mind; she's looking for revenge. Not every crime fighter shares Black Label's scruples, but more than her ruthless methods, it is Fever's true identity that proves the bigger shock to Mikoto...

Yuuko returns to her childhood home to confront a shadow from her past. Darkness has consumed someone who was once family-and turned her into a deadly enemy. But Yuuko has forged new bonds in Black Label, and with their support, she is able to sever this last link to her past. As Syringe threatens to unleash the next stage of infection upon the city, Yuuko and the team return to the "operating theater" once more!
