Description
Shun Imai is a supporting character in the series, identifiable as a 24-year-old skunk. He works as a waiter at a cabaret club called the White Dolphin in Kabukicho.

Imai's most defining trait is his role as an extremely devoted and enthusiastic fan of the idol group Mystery Kiss, with a particular fondness for the member Rui Nikaido. He spends a significant portion of his income on the group's merchandise and concert tickets. His personality is notably optimistic, straightforward, and energetic. He maintains a cheerful and laid-back demeanor, which provides a contrast to the increasingly tense events of the main plot. His earnestness can make him seem naive, yet his passion is generally viewed as more wholesome than obsessive. He carries himself with the confidence and charm befitting someone in the service industry, presenting a friendly and approachable appearance.

Imai's primary motivation stems from his fandom, but his role in the story escalates dramatically after an unexpected stroke of good luck. He habitually rides in protagonist Hiroshi Odokawa's taxi, and during one ride, Odokawa offhandedly gives him a set of numbers to use for a lottery ticket. Against all odds, Imai wins the grand prize of one billion yen. This life-changing event shifts his motivation from simply supporting his idols to expressing his gratitude towards Odokawa, whom he sees as the source of his fortune. He persistently tries to repay Odokawa by offering him money or gifts, only to be politely turned down. Instead, his gratitude leads him to involve Odokawa in his world, such as by bringing him to his workplace at the cabaret club. This luck, however, places him in a precarious position, making him a target for the criminal elements who seek to take his money.

A key relationship for Imai is with Hiroshi Odokawa. Imai holds a blind and unwavering trust in the taxi driver, a sentiment Odokawa does not entirely reciprocate but must manage. Their connection is the primary way Imai is woven into the central mystery. He also has a professional relationship with Kensuke Shibagaki, one-half of the comedy duo Homo Sapiens, who works a part-time job alongside him at the White Dolphin. This connection later becomes a crucial link in the chain of events during a crisis at the club.

Imai is not a character who undergoes a profound emotional or moral transformation. Instead, his development is demonstrated through the consistency of his positive attitude in the face of mounting danger. Winning the billion yen does not corrupt him or change his core personality; he remains focused on his fandom and his desire to help Odokawa. He shows remarkable resilience and an admirable mindset, even when later confronted with the knowledge of his idol's imperfections. His journey is less about internal conflict and more about navigating the external chaos his sudden wealth brings, all while maintaining his inherent optimism.

Imai does not possess any special combat or investigative abilities. His most notable capability is his staggering good luck, as represented by his lottery win. Furthermore, his knowledge of the White Dolphin's layout, including a secret backdoor, proves to be a practical ability that allows him to help Odokawa escape a life-threatening situation. Beyond that, his primary function within the narrative is to act as a source of light-hearted relief and a catalyst for certain plot developments, rather than an active agent of change.
