* Based on a series of light novels written by Nishio Ishin and illustrated by Vofan.

After that spring break when he met a beautiful vampiress, just before meeting that girl who fell from the sky, on the first day of Golden Week, Araragi Koyomi and class-rep Hanekawa Tsubasa bury a tailless cat which had been run over by a car. Normally, that would be a trivial matter, but in this case, it leads to the "Nine Days' Nightmare".
