Gaku Tanaka "An active, lonely-hearted, and passionate creator." He is actually the type who can be outgoing. While he has a fundamentally introverted side, he is more social than his partner Hyoga and can flip a switch to become the life of the party. He has a cute side where he hates being alone and loves spending time with others.

Hyoga Takada "A laid-back, incredibly kind-hearted, and beloved natural genius." He is an unwavering, pure introvert. He describes himself as a "gloomy, socially awkward homebody." He is so incredibly kind that his partner Gaku vouches for him as "the complete opposite of 'tough'—a truly gentle person," possessing a calm personality without a sharp edge to be found.
