Plot

In 1983, off-duty policeman Reiden picks up a suspicious couple, Kei and Ai, who claim to be father and daughter but appear to be close in age. Reiden thus becomes involved in a fight between them and the female fighter K2 who is chasing them. Kei draws out his latent ability to the maximum by a Legendary "Trigger" and Ai blows away K2. The night sky splits and strange space is shown. Their enemy is the secret society "Fraud" of para-psionics, which is commanded by Kuu Ragua Lee. Kei, Ai and Reiden meet the assassins whom Fraud sends out one after another.

Characters

Ai's companions

I2 (Ai)

Ai is Headmeters who escaped from Fraud with Kei, but she does not have the operation yet. Her original name is "I2". She is a clone of Kei's lover Etsuko (also known as "I") who was killed by Fraud, and adores Kei as a father. Fraud suspects that she is legendary "Trigger" who draws out others' dormant faculties and amplifies them, and so pursues her. "2" of "I2" stands for "the second generation of the clone of Headmeters I". However, nobody of Headmeters knew who "I" or "I2" are, there is no information about the two in the memory bank of Fraud's computer, and "Headmeters I" is a missing number. It is not clear why they recognized "I" and "I2", but the two people did not exist actually.

K (Kei)

Kei is Headmeters who escaped from Fraud to defend Ai. He was anaesthetized suddenly and was made to undergo the operation for Headmeters on his college days. He was given the code name "K". He was proud of being Headmeters, but he became despondent because his lover Etsuko died from the same operation as him. Then, a girl appeared who was just like Etsuko, only ten years younger. She introduced herself as Ai-"I2". "I" was a code name of Etsuko. Kei decided to behave as her father.

Kei has both abilities of Headmeters and Tuned-man exceptionally, because Kuu Ragua Lee, the leader of Fraud, operated on Kei in person. However, he is a defect product as Headmeters and has only the faculty for incomplete mind reading. The number of his headmeter has risen only to level 5 by the shock of Etsuko's death, but the number rises to infinite when Ai draws out his latent abilities. His performance as Tuned-man is less than 1/10 of the output of Yi or Lyan, but Fraud performed the operation which is different from them on Kei. Sensors which are embedded on the 108 vital points of his body control his muscles, internal organs and brain, and he can always utilize his muscles at 100% (people usually use only about 20%).
