History
Darii was a parasitic alien monster that travelled to earth and found refuge inside a flower pedal. When a girl named Kaori sniffed the flower, Darii was sucked into her nostril and from there began to take control of her. As the Ultra Garrison did some research and found out that the microscopic Darii was inside of Kaori, Darii used Kaori's body to sparodically enter a trance-like state in her sleep to search for other humans that share the same blood type as Kaori in order to feed on it. Amagi was one of them, and Darii used Kaori's affection to earn his trust, only for the Ultra Garrison to force Kaori into an unconcious state until an antidote could be developed to stop Darii from inside Kaori.

Rather than wait, Dan transformed into Ultra Seven and shrunk himself down to a microscopic size and entered Kaori himself through her nostril. Upon entering her body, Ultraseven found Darii cling to a wall of her flesh and sipping on Kaori's blood. Ultra Seven tried to stop the parasite quickly with its Emerium Ray, but all it did was release Darii from its host and sent Darii on the offense. After a quick staredown with Ultra Seven, Darii reattacted itself to Kaori's flesh and coated Ultra Seven with a white mist attack, which immobilized Ultra Seven and making the battle seem one sided. Fortunalely the scientists of the Ultra Garrison finished the antidote, and injected into Kaori, severely weaking Darii. With the opporitunity, Ultra Seven used his Hot Bubble Stream to melt Darii into a pile of foam. With Darii dead, Kaori was freed from the parasite's control
