Halloween's Prank Magic Has a Delayed Effect

Itariyama Hiki, who just became a middle school student this year, was going to stay at the nearby Shinonome household. Today is Halloween. A day when many children go around begging for candy. On such a day, strange things tend to happen. The Halloween boy she met on the way to the sleepover wanted candy. However, since she didn't have any on hand, she gave him cat candy instead, and he vanished in an instant. Though puzzled by this, she didn't think much of it and was relaxing at Shino-nee's house when she noticed a cat tail had grown on her. Shinonome Shino, the only daughter of the Shinonome household who had taken an interest in her tail, suddenly changed and attacked her. This year's Halloween was an extraordinary day, unlike any other.
