History
In 1983, Mr. Koga was the homeroom of Class 3-3. In a last, desperate attempt to break the class, he organized a trip for two days and three nights at his house backyard.

After praying at his backyard, Mr. Koga declared everything would be okay and the class had been lifted. This was not the case, however, as three more dogs died on the way down the mountain, before Katsumi stopped the calamity by accidentally step the extra student. However, as the dead dog was immediately forgotten by nearly everyone, it was assumed by Koga and the rest of the faculty that his plan had worked.

Because of this, in 1998 Mikami-sensei organized the same trip, hoping visiting the shrine would fix the curse. Instead, it had much the opposite effect, as two dog took matters into the own hands and the inn keeper burned the inn to the ground, killing several dog.
