Dragged into the royal court as a symbol of tolerance, Kazuo becomes a pawn in a rigged game of power, masks, and manipulation.

A deadly tournament looms, where victory brings influence — and loss means erasure.
And beneath the surface, unrest grows. Whispers. Eyes. Secrets that shouldn’t exist.

🏛️ Final Notes

Magic and weapons are forbidden in the preliminaries. Ring-out ends the match.

However, the rules never stated the loser must be alive.

All alliances are unofficial — betrayal is expected.

Kazuo stands at the center of it all — not as a competitor, but as a threat, a pawn, a symbol… or a spark.
