A girl has her clothes torn off inside a church as a mysterious masked figure lights a buttload of magnesium flares inside just to prove some kind of point.
The next day, Tomo and Mafuyu are going through their normal day, running across a cat-eared nun named Sister Teresa, getting bullied by Miyuri and Hana, and studying at a Eastern Orthodox-themed Christian Academy in Japan when they stumble across a young white haired person of ambiguous gender. It gropes one of Tomo's gigantic chesticles and Mafuyu responds by whacking it with her shin'ai and dragging him/her back to their dorm. However, the person escapes and as she attempts to find him Mafuyu sees that the church is on fire. Rather than doing the smart thing like calling the cops, she decides to run into the burning building, where she is trapped by the same masked person from the beginning, the Qwaser of Magnesium.
Just as all hope seems lost, the silver-haired youngster from before leaps in to save the day by sucking on Sister Teresa's breasts and using her "Soma" to form his gigantic iron scythe, cutting the heretic Qwaser in half as the church burns down. However, the next day the same church is miraculously repaired as if nothing happened. The silver-haired boy from before shows up in Mafuyu and Tomo's class as a transfer student from Russia named Alexander Her, and because of his looks and stature the girls all love him. Miyuri and Hana try to recruit him because he is the big man on campus, but he doesn't take their shit.
