Touya Mochizuki is settling into his new existence in a different realm. Equipped with his reliable smartphone, the adolescent takes on minor missions at will while enjoying moments with his new betrothed: Yumina Urnea Belfast, Yae Kokonoe, and the twin pair Linse and Elze Shileska. Yet even amid a calm setting, Touya is just beginning to grasp the duties tied to these commitments. Alongside his love troubles, the senior fairy Lean seeks to find the remaining fragments of Babylon, the airborne isle that Professor Regina Babylon fashioned five millennia ago. Reluctantly, Touya accepts her plea and hunts for the teleportation circles that will guide him to those islands. Yet bizarre beasts have surfaced—perhaps strong enough to annihilate the world. To preserve the second life bestowed upon him, Touya must harness ancient tech to battle these creatures—all while juggling his vast array of relationships.
