Akira, (I think, the kanji is 晶) a young boy, shows up at the detective office. His sister is missing and Shotaro decides to investigate it. Shotaro decides to go to the high school that she attends to. Shotaro hears about a rumor that there is a student trading Gaia Memories. (In the magazine it says ガイヤ instead of the usual ガイア. It's either a misprint or cheap imitation memories. Most likely misprint)
Not only that, Shotaro hears from Queen that she believes she saw Phillip.
