Intro
"Run Treasure" has been a massive hit for years. Guest has been a long-time player and was waiting leisurely for an opponent today.
Opponent found. Commencing match.
The opponent's name is "M." Guest immediately saw through their weaknesses and completely dominated them.
His eyes widen.
...Huh?
I lost. Me. I should be frustrated, but for some reason, my heart is pounding. It feels like it's been seized.
...Whatever, I just started this on a whim. I haven't even practiced yet.
Until he faced Guest, he had defeated every other player. Perhaps because of that, he absolutely refused to acknowledge this defeat.
