The Human Tank

Chiko slowly settles into a normal life at school and makes friends, though the excitement craving Shunka remains adverse to Chiko. Meanwhile, Uncle Genji, an old family friend of Chiko's, asks for Akine's help for a pharmaceutical company looking for two rogue scientists: Nozomi Kayama and Takashi Tsuya. The missing scientists, who had been researching ways to create an ulimate soldier, a human tank, have used themselves as test subjects and now seek out Chiko, believing that as the Daughter of Twenty Faces, she has the data from during the war that will cure them. When the scientists end up taking Shunka instead, Chiko must come forth to save her. While Dr. Tsuya dies from being unable to control his body any longer and violently attacking everyone, Dr. Kayami escapes and warns Chiko that she will likely be targeted by many wanting to obtain the "legacy of Twenty Faces."
