Dementia 21 Vol. 2 (manga)

In Vol. 2, Yukie boldly decides to join the resistance -- against a squadron of maniacal diapers hell-bent on taking over the world! A shorthanded hospital hires zombies to care for its patients, but ... what exactly do they eat? When an old man creates a machine that causes out-of-body experiences, what could possibly go wrong? And why are children getting rocket launchers in their stockings? Three words: Santa has dementia!
