Having overcome countless trials (without much difficulty), Yogiri and Tomochika finally managed to reunite with their classmates in the capital. But between the efforts of Ayaka, a synthetic classmate who swore revenge against her fellow students, the meddling of Sion, a Sage determined to cull the weak and produce a new superbeing from their class of candidates, and the revival of the Dark God Mana, the majority of the class -- not to mention the entire capital -- were ultimately wiped out. Somehow, amid the chaos, the unlikely pair were able to draw Sion out and acquire their first concrete clue about how to get home: they will need a number of Philosopher's Stones, powerful artifacts carried within the bodies of the Sages.

In hopes of finding any information that might help them get home, the two reluctantly decide to participate in the trial unfolding there: a selection process for those wishing to become Knights of the Divine King. But when Yogiri slips up and accidentally uses his power to kill someone central to the history of the world, their objective quickly changes to escaping the tower where the trial is being held before anyone realizes what he's don
