Synopsis
Keito Yuki, a boy visiting Ikebukuro, Tokyo, is attacked by a gray "dragon" that suddenly appears. It was a dragon tribe of another world, Nizreg, who had the power to turn "everything that moves" such as airplanes and cars into a dragon. It was Kukuru, a girl from the same dragon tribe who came to stop Nizreg, who saved the seriously injured Keito.

In the midst of an unprecedented situation involving the Self-Defense Forces and the US military, Keito, who was in the midst of a whirlpool, is now fighting for the fate of 130 million Japanese citizens.
