With the help from friends, both Tohrus arrive at the spot specified by the Timekeepers after a fierce battle. In the middle of a gunfight there, they suddenly receive notice to end combat.

While the two try to grasp the situation, the individual starts explaining the true reason why the two worlds "Frontier S" and "17th Far East Imperial Management District" must fight each other.
