Character setting
- Male protagonist: Isana Kaito
21 years old, a new member of the Kyoto Prefectural Police. He always carries a field notebook and is nicknamed "trainee" because of his young age. His true identity is the United States' FBI, which focuses on the mental control of high school students by transnational organizations.
- Second male: Cangyelian
21 years old, a clerk at a record store next to Sakuragaoka High School. He often stuffs Kaito with old song tapes. In fact, it is Japan's "Hoshimi" FBI, investigating the infiltration of foreign forces, and Kaito knows nothing about each other.
- Heroine: Shiratori
17 years old, the school beauty of Sakuragaoka High School, loves to write notes in the corner of the Gion used bookstore. Witnesses of the third "jumping off building case" said that the deceased said to the night sky, "The moon is eating shadows" before falling.
Story events
At the scene of the third case, Kaito found a rolled-up piece of Japanese paper behind the drain pipe on the rooftop, and unfolded it to reveal a children's painting: a crooked moon holding a little man in school uniform in its mouth, and a cherry blossom seal stamped in the corner - exactly the same as the seals in the textbooks of the previous two victims. When Shiratori was taken to the police station, the cuffs of his school uniform were stained with gold powder, which was the same composition as the moon in the painting.
"They go to the used bookstore basement every Wednesday. "She suddenly spoke, drawing a five-pointed star on the interrogation table with her fingertips, "They say they want to 'feed shadows' to the moon. If anyone doesn't go, the shadow will be eaten. When Kaidou asked, her eyes straightened and she repeated the deceased's words: "The moon has no face, so it steals people's faces." "
Kaito went to the record store to ask Cangye to borrow the floor plan of a used bookstore. There was a note hidden in the tape box he handed over: "In the 1998 Sakuragaoka High School fire, an art teacher who painted the moon died. "Hai Dou was stunned - he is a reasoning type, not a high martial artist.
