Mashiro Kuroki and his wife, Haniko Kuroki were a married couple yearning for a child of their own. Haniko was unable to bear a child. One night, while driving back to Tokyo, the two come across a meteor that fell into the woods.

When they discover crying coming from the pod, a hatch slowly opens up to reveal a crying baby inside. After a bit of contemplation, they adopt the child and name it, Chisuke.

The family lives in the city of Tokyo happily. As Chisuke grows older, she started to experience hallucinations and even hears voices whispering in her ears. At times, her heart glows a bright red hue so radiant that it glows through her skin and clothes. Things began to take a sinister turn as Chisuke begins to develop powers and harbor homicidal thoughts which may be induced by a signal transmitted through her brain via an other-worldly source.

The National Special Investigations Department which specializes in studying cases with extraterrestrials discovered the spaceship a year later and after uncovering a blood sample that didn't belong to any known person in Japan, they suspect that the blood that originated from the creature within the spaceship could still be somewhere in Japan. N.S.I.D investigator Naohiro Miyata finds out Chisuke is the alien. When he finds out that she is being raised by a loving family, Naohiro finds himself in a situation whether to report his discovery or let the family be.

But what about Chisuke? Will she be able to fight to stop the signal in her mind to possess her and complete what she was initially sent on earth for, or will she resist the signal's orders and remain a human?
