Maria tells Colette that she is looking for "Necronomicon", a dangerous magical grimoire. Due to a misunderstanding, Yumeko also joins in the search. Meanwhile, the president wants the porn magazine (from "Let's Treasure Hunt") for himself. When Yumeko enters the clubroom, she says the grimoire's name incorrectly, and the president thinks she meant "Nekomi Lock On", which is written in the front cover of the magazine. This forces Mizuki and Subaru to hide the book under Subaru's shirt, as they try to make it out of the school. Colette and Maria find them acting suspiciously, and Colette thinks Subaru is trying to hide "Necronomicon" under his shirt, and snatch the magazine from him after a struggle...
