Excitement! The Halloween Costume Contest Fuyutsuki is interested in a Halloween-themed iced coffee. Himuro buys four so Fuyutsuki can try it with Saejima and Komori. At the office, however, he finds that Fuyutsuki, having had the same idea, also bought four. They find this funny and share the extra cups of coffee with Katori's group. The company president, a descendant of the Nurarihyon spirit, decides to host a Halloween party with a 100,000 yen prize for best group costume. It is decided that everyone will dress as pumpkins, though Fuyutsuki is disappointed that the pumpkin costumes are sold out. While looking for other costumes, Fuyutsuki finds high class vampire costumes and Himuro nearly freezes the shop...
