Storyline
Yamada is once again trapped in the hospital, still dealing with his unusual condition and the consequences of his injuries. Unfortunately, the nurses are only the beginning of his problems.
At the center of the hospital is Head Nurse Tendo, a ruthless woman who holds extraordinary power over the doctors, administration, and even the hospital director. Driven by her desire for greater authority and wealth, she is willing to use whatever means necessary to achieve her ambitions. Her younger sister, Mia Tendo, is one of the hospital's feared veteran nurses and is just as unpredictable.
Things become even more complicated when Yamada discovers that the hospital has connections to the criminal underworld. At the same time, an undercover police officer is investigating those connections and asks Yamada to cooperate with the investigation.
As the different factions begin pursuing their own goals, Yamada finds himself caught in the middle. His own ward is eventually placed under quarantine, leaving him with even fewer options for escape. With criminals, police, nurses, and the hospital's powerful leadership all closing in around him, Yamada must decide whom he can trust and whether he can uncover the truth before it is too late.
The final chapter transforms Yamada's hospital nightmare into a dangerous mystery involving power, crime, investigation, and survival.
