With Rabbi Village greatly expanding under the management of his subordinates Isami Tahara and Yuu Kirino, Hakuto Kunai can now resume his adventures while looking for items to counteract magic. He begins his search at the Prison Labyrinth in Rookie Town, where a secret laboratory deep within the dungeon gives him insight into technology that is far more advanced and dangerous than anything in the rest of the world. Meanwhile, Rabbi Village has gained unwanted international attention from the newly formed Queendom of Xenobia, which wishes to drive a wedge between the Holy Kingdom of Light and the State of Right. But with Kunai's newly summoned aide, Akane Fujisaki, at his disposal, things may not go as the Queendom plans.

In 2061 CE, humanity's indiscriminate pollution of space has substantially hindered the development of space travel. In response, an international federation has designated the sun as a natural incinerator, federally establishing a treaty with the goal of first processing hazardous waste on Jupiter and forming the space environment defense force Cosmo Ecology. However, polluters evading surveillance networks continue to illegally dispose of radioactive waste directly into the sun. As a result, increased solar flare activity is on the verge of turning the Earth into a desert. (Source: ANN)
