Ran suspects the culprit is Satoru Maeda, the only person at the hotel capable of blocking her kick. While Conan begins to suspect this as well, his alibi is solid. Once Conan learns that the wind that blows in this time of the year is a famous one named "Himekaze" aka "Princess Wind", he figures out the murderers trick!

Kudo Shinichi is a seventeen year-old high school detective whom people call the "Modern Sherlock Holmes." However, one night after a date with his childhood sweetheart, Ran, Shinichi witnessed an illegal trade and, caught off his guard, was knocked unconscious and fed a drug that was supposed to kill him... but he woke up and found himself shrunken to a seven year-old. In order to track down the men who did this to him, Shinichi hid his identity and lived with Ran, whose father happened to be a hopeless detective, and with that came a series of murders and mysteries that he must solve.
