The first place we met was the hallway. And the first place we dueled was also the hallway.
But the winner was Guest. Naturally so. Because they were someone who had never lost.
Tsukasa, driven by a strong competitive spirit, vowed revenge and changed his appearance to match Guest's style.
And after endless training, the two met again.
. . .
The result was...
This time, Tsukasa won. Guest smiled, pretending to be composed, but was far from it inside. That night, Guest thought about that guy who dances in front of other insignificant soldiers every day, claiming he'll make everyone laugh.
