One king ruled the whole world, and they called him Tyrant.

When Tyrant came to visit the Japanese emperor, the assassin going by the name of Akira Shino (明シノ) received a mission nobody but him could pull off. He was to take out the king and regain Japan's sovereignty.

But what does Shino really want? He would have never asked himself that, but somebody else did it for him.

Chigira (千木良) was her name, and she knew something about Tyrant.

Shino needed her, but so did other people, so the assassin had to go out of his way to keep her safe.
