Infinite Dendrogram: Volume 4 (Light Novel)

The only way to win is not to play?!The city of duels is suddenly besieged by one of the Dryfe Imperium’s Superiors. Mr. Franklin, the Giga Professor. Both admirably cunning and incorrigibly heinous, the sadistic scientist sets his sights on throwing Gideon into utter Pandemonium. As luck would have it, Ray, Marie, and Rook are caught right in the middle of his malicious machinations. Though outmatched, outnumbered and outsmarted, the knights and Masters of The Kingdom of Altar don't hesitate to retaliate. They have the spirit, no doubt, but will it be enough to defeat the mastermind of Franklin's Game?
