Approved! Natsume finds his gatling gun leaned up against his bed the next time he returns to the dorms. It is stocked full of dried beans. The pendulum and pentagram necklace will be found underneath his pillow when he goes to bed.

Natsume makes the conscious decision to buy these rosary beads, they're the only ones Keigo has in stock, they recommend Natsume buy some keychains too, they're part of a set or something
