Dandy is a male character who serves as the former leader of the Aichi National Vigilante Corps, an organization also known as the Aichi Tenmusu. In his current life, he is the owner and operator of a coffee shop called Mach Mountain. Despite not possessing a special stone that grants powers, Dandy is classified as a Mosa, a term used for individuals with remarkable, natural prowess. His most defining trait is his extraordinary physical strength and agility. A clear demonstration of this ability occurs when a motorcycle crashes into his shop; Dandy stops the vehicle effortlessly with just one arm.

In addition to his physical power, Dandy has a legendary past as a renowned rider operating under the name Daijiro Motoya. His racing number, 74, is said to be so iconic that it has been permanently retired, marking his legendary status in that world. His personality is defined by a generous and dependable nature. This is notably illustrated when his friend Tomoki Suzuka’s motorcycle is sabotaged during a race against Akogi. Without hesitation, Dandy lends his own motorcycle to Tomoki, demonstrating a strong sense of sportsmanship and deep care for his friends. As a coffee shop owner, he is also known for an open and helpful demeanor that is appreciated by his guests.

Dandy’s role in the story is that of a former hero and mentor figure. His background as a vigilante corps leader and legendary rider establishes him as a person of great capability and respect. His primary relationships are with his friends, including Tomoki Suzuka, to whom he shows profound loyalty, and Akogi, whose actions create a challenge that allows Dandy to display his character. His development is reflected in his transition from the active, high-stakes life of a vigilante leader and racing legend to a more settled, supportive role as a café owner, yet he remains ready to act with strength and kindness when others are in need.
