Now, living alone in a contaminated zone, Kaito finishes what he started. — “my vaccine” — doesn’t block infection. It reverses zombification by restoring the victim’s original neural patterns. He tests it on a zombied dog. It wags its tail. Then on a human. She asks, “What happened to my hands?”

His "vaccine" ability isn't a magical cure-all. It requires him to physically risk his life to acquire samples from special infected, making him a vulnerable, high-stakes protagonist.
The series operates as an explicit parody of survival horror classics like Resident Evil or Highschool of the Dead . Rather than scavenging for ammunition or building fortresses, Yu’s survival strategy requires him to deliberately seek out and interact with infected females to save humanity. 2. From Hikikomori to Messiah
While the premise is played for laughs, the underlying themes are surprisingly dark. The idea that the only way to save a loved one is through a sexual act creates a deep well of psychological horror.

The main character is not an elite soldier or a brilliant scientist; he is an ordinary individual holding absolute leverage over human survival. This creates a moral dilemma that the story frequently plays for comedic and romantic tension. 2. The Safe Haven Harem
The manga blends genres fearlessly. It's tagged with Horror, Supernatural, Seinen, and Ecchi . The ecchi elements are not merely for titillation but are integral to the plot. The act of "vaccinating" zombies is presented not as a romantic ideal but as a bizarre, messy, and often panicked necessity. This creates a unique brand of dark comedy where the protagonist must navigate post-apocalyptic survival scenarios while also trying to figure out the logistics of his own powers.
