Charlie is a mysterious magician who transports protagonist Mei Ayazuki from a modern summer festival back to the Meiji era under a crimson moon, utilizing a magic box that shatters a mirror. He operates under the alias Charlie, though his true identity is Tenichi Shokyokusai. Exclusively appearing at night, he serves as Mei’s cryptic navigational guide, offering enigmatic insights about her circumstances. Charlie exhibits an aloof and playful demeanor, frequently making flirtatious remarks such as enjoying being "abused by the protagonist" or suggesting they "pretend to be lovers." His primary skill is magic, complemented by a height of 182cm and blood type AB. Beyond displacing Mei through time, he informs her she can return during the next full moon and complicates her situation by gifting a stolen pocket watch. In the sequel, *Gekijōban Meiji Tokyo Renka: Hana Kagami no Fantasia*, Charlie is revealed to have manipulated events years earlier by orchestrating Mei’s childhood encounter with Kyōka Izumi through the mirror. He reappears near the full moon to confirm Mei’s return opportunity but ultimately conducts a magic show allowing her to stay in the Meiji era after her choice. Charlie traverses time and dimensions via the mirror, collects its shards, and influences pivotal events across both films, his motivations remaining unexplained and cloaked in mystery.
