As Rabbi Village expands significantly under the supervision of his subordinates, Isami Tahara and Yuu Kirino, Hakuto Kunai is now able to resume his adventures in search of items to counteract magic. He starts his search in the Prison Labyrinth located in Rookie Town, where a secret laboratory deep inside the dungeon reveals technology that is far more advanced and dangerous than anything found elsewhere in the world. Meanwhile, Rabbi Village has attracted unwanted international attention from the newly formed Queendom of Xenobia, which aims to drive a wedge between the Holy Kingdom of Light and the State of Right. However, with Kunai’s newly summoned aide, Akane Fujisaki, at his disposal, events may not unfold as the Queendom intends.
