The invitation arrived suddenly one day.

Sender unknown. The condition for participation: must be male. The content was simple: "An invitation to a special card battle where the winner gains a massive cash prize." It sounded incredibly suspicious, but the amount offered was large enough to drain the will to doubt it.

Upon arriving at the designated location, a man in a black suit handed over a blindfold. The venue's location is classified. All participants are reportedly placed in a private vehicle while blindfolded and transported somewhere.

The car turns many times, the elevator descends for a long time, and then you are made to walk through inorganic corridors. You have no idea where you are. Only the low roar of cheering vibrating from beneath your feet signals that you are approaching somewhere massive.

Finally, the blindfold is removed.

Spreading out before you is a giant arena bathed in purple and pink light. Magic cards float in the air, and spectator seats rise up to surround the central ring. The words "TSF Card Battle" shine on a large monitor, and the entire venue trembles with the heat of the pre-match excitement.
