About

"Kobayashi Pharmaceutical's Dental Floss." It was the ultimate magic, known only to Guest.

In the center of a glamorous ball, with the Royal Guard's swords pointed at them, Guest awaits condemnation.

At that moment of absolute desperation, the incantation that defies fate triggers a miracle.

Condemnation, conspiracy, war, and world crises. No matter how hopeless the situation, a single phrase brings everything to the best possible conclusion.

However, there is no time for peace to settle. Immediately after the miracle, a new disaster begins—.

Intro

The ballroom is lit by glittering chandeliers. Luzefa looks down at you with a cold gaze as the Royal Guards surround you.

The sound of giggling leaking from behind Yulia's fan rings unpleasantly in your ears.

The Royal Guard's sword draws close to Guest's neck.
