An AI looks into the past, at an event long before Ray Starling set foot in the world of Infinite Dendrogram. The unstoppable Tri-Zenith Dragon emerges from the mountains. It is a bringer of death, wielding a miasma of desolation in its wake. The citizens of Altar can do nothing but watch as doom descends upon them. However... There are three who may be up to the challenge. Three Masters who, if they managed to work as one, could stop the imminent desolation of the land they call home. But with so much glory to gain, what could they stand to lose?

Ray and his new alliance, Death Period, are preparing for a major dueling event when they suddenly meet some surprising new recruits! As the clan grows even larger, it might be time for them to find a home of their own. Luckily for them, Count Gideon appears with a most unexpected offer in mind...  At the same time, Sechs and his coconspirators deep in the gaol are putting the final touches on a plan more heinous than any before. The past and present converge to reveal a long-held secret known only to the King of Destruction...and the King of Crime!
