However, a detective called Akechi showed up and hinted that Twenty Faces may still be alive. Chiko cheered up and started to accept Tome's hospitality. Also, Chiko decided to go to school. In school, Chiko met Shunka who is the granddaughter of the founder of Chiko's school. Later in the episode, Chiko met Akechi again and Akechi gave Chiko the Anastasia Ruby (which is supposed to be possessed by Twenty Faces). Believing Twenty Faces is still alive, Chiko decides to start looking for Twenty Faces as a detective.

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."

Chiko uses an movie shoot as an excuse to visit "White Hair Island", where she may find information regarding Twenty Faces. Upon entering the island, Chiko spots Ken whom she had thought dead. Later, when the two get a chance to speak to one another, Ken reveals that he blames Twenty Faces for all the misfortunes that have befallen him after his "death". A man is murdered on the island, and Chiko decides to investigate the occurrence. Chiko is captured by a mysterious white haired person, who reveals that he wants to find and kill Twenty Faces. The "White Haired Devil" moves to kill Chiko, however Ken arrives and manages to stop her. It becomes obvious that the "White Haired Devil" is not susceptible to injuries, however manages to trap her. Ken quickly disappears, and Chiko and Shunka then return home.

Chiko has found a "secret spot" which she now visits regularly (as stated by Shunka). While there one day, a man she's never seen before is sitting alone. He tells her about the memories the hill brings back to him. Chiko remembers a song Twenty Faces taught her. Later, the man introduces himself as Kakashima Kouhei, a teacher of Twenty Faces from long ago. He tells Chiko she is just another pawn in his, Twenty Face's, plans. This confuses Chiko, who ultimately decides she will believe in Twenty Faces. A teacher tells her the song is actually a French poem about the "law of men". While walking home after searching for more on the song Chiko is attacked by a mysterious boy who is incredibly fast and strong, only to be saved by Ken who tells her to stay safe.

Chiko goes with Kouhei, leaving a note on her bed for Tome that she will "definitely be back". Ken sees Chiko in the car and follows but is attacked by a girl who is very much like the boy who attacked Chiko last time. It doesn't seem she can be wounded as she is hit by a metal object of some sort on the road and has no injuries from it. Ken lights the girl on fire, destroying his motorcycle, yet to his surprise the girl has not a scratch and comes at him again. This time, Dr. Kayami intercepts it (the girl seems to be a more stable experiment much like Dr. Kayami herself). They escape. Meanwhile, Chiko and Kouhei have gone underground to a secret laboratory where Kouhei is trying to create the "Fourth Form of Water" which is light. Chiko has connected this research to the poem and refuses to help Kouhei. He shows her that he has Shunka captive and will use her in an experiment if she does not help him. So she give him what he wants, only to be deceived. Twenty Faces shows up and rescues Shunka before facing Kouhei.

Twenty Faces and Kouhei go head to head. Twenty Faces manages to distract Kouhei long enough to let Chiko rescue Shunka, only to be captured by the emotionless girl/weapon. Ken and Dr. Kayami meet up and discuss Twenty Face's "legacy" while heading towards Kouhei's laboratory. Kouhei seems to have the upper hand as he unleashes his human experiments on both Chiko and Twenty Faces. He succeed in inserting the parameters he needed and 3 large towers appears in the center of Tokyo. Restrained by the children, the two can do nothing but watch as the city starts to be consumed by the light. Until Shunka escapes and creates a distraction, which Twenty Faces uses to blow up the machines. After the rumbling has subsided, Chiko is shocked to see Twenty Faces lying on the ground, unmoving.

Chizuko, Ken, and Dr. Kayami Head towards the tower to stop Kohei and meet up with Twenty Faces. When almost there, the genetically enhanced children fire a rocket at the airship. Chizuko hops off onto the tower, while Ken and Kayami crash land onto the roof. As Ken and Kayami fight the children formulating a plot to defeat them, Twenty Faces appears in the control room of the tower, where he meets Kohei. Twenty Faces shoots Kohei between the eyes, but to no avail. It is shown that he has created himself an artificial body, using the White Haired Devil's research. During their dual, Twenty Faces burns Kohei revealing that he made himself look just like Twenty Faces. When it looks grim for Twenty Faces, Chizuko shows up. After a brief conversation, Chizuko declares herself to be Twenty Faces daughter and vows to defeat Kohei. Though at first it appears she has a chance, this is quickly dispelled as he overpowers her. Forcing her to push the lever which re-initiates the Fourth Phase of Water weapon, the weapon goes fires.
