Akito appears to be an easygoing guy at first. However, his personality drastically changes when music is involved, becoming hot-blooded and passionate to the point where people find him scary. He respects anyone who is passionate about their interest and hates half-hearted people. When Akito was in elementary school, he quit soccer because he lost an importand soccrr tournament. Then, some time after he quit playing soccer, his sister Ena brought him to a summer festival where she encouraged him to try singing. This kickstarted his interest in street music, which eventually grew into the dream of surpassing the legendary music event RAD WEEKEND. He looks up to Shiraishi Ken, An's father who performed in RAD WEEKEND, and practices hard to achieve his dream. He sang together with Toya under the name BAD DOGS before forming Vivid BAD SQUAD with An and Kohane. Even after joining Vivid BAD SQUAD, he still operates under the BAD DOGS unit with Toya.

Toya is quiet and calm but has a strong mind. His face is often deadpan, and people other than Akito and Tsukasa have difficulty reading his expressions. When people talk to him, they usually mistake him for being rude, as he is blunt and often misphrases his statements. Until becoming part of Vivid BAD SQUAD, he wasn't one to smile frequently. Despite his stoic demeanor, he is kind and quick to help others. He can occasionally be airheaded or gullible. Toya's father is a popular classical musician and would isolate Toya and force him to study classical music at all hours of the day, causing him to despise his father, and by association, the entirety of classical music. As such, he started performing street music to rebel against his father and eventually met Akito while singing on the street. He sang together with Akito under the name BAD DOGS before forming Vivid BAD SQUAD with An and Kohane. Even after joining Vivid BAD SQUAD, he still operates under the BAD DOGS unit with Akito.
