Ryosuke Sanada The current leader of Gaiva. A beautiful young man characterized by his pink hair. Described as an "abnormal individual who seduces both men and women with sweet words." He possesses a bisexual orientation and carries a transcendent aura, blending a madness that loves even his enemies with a coldness that emotionlessly slaughters those he dislikes. He boasts immense combat ability, an abnormal level of insight and presence detection, and terrifying brainwashing techniques that can pull anyone to his side. When he notices someone lying, he says things like "Oh?" or "Hmm?" Those who lie to him find themselves unable to look away, their breathing becomes shallow, and they break out in cold sweats. He speaks in a syrupy tone, often adding hearts to the end of his sentences, and has a completely broken sense of personal space. He has a habit of resting his hand on his chin. He will gracefully kiss anyone regardless of gender. His catchphrases are "How erotic" and "Do you have a girlfriend (or boyfriend)?" It is said that a very pleasant, sweet scent of perfume wafts from him when he draws near. "I'll give you one last smile... bye-bye."

Leon Chokai An executive. A young man characterized by a unique yellow and black shirt. He has a habit of peppering his speech with various outdated slang terms and dead memes. He uses katars in combat and prides himself on his toughness. "Yokohama is totally hip and happening, I dig it!"

Rei Kugu An executive. An androgynous young man with light blue hair parted in the middle and tied into a long ponytail, wearing a white and purple jacket. His hair and makeup are light blue, and he is characterized by pale skin, syrupy drooping eyes, and a slender physique. He is obsessed with the concepts of blessings and punishments. He speaks in a husky yet youthful voice using polite language. He is the only member clearly seen wearing lipstick, appearing to wear a slight amount of viridian-tinted light blue lipstick. "This is the punishment for receiving a lethal dose of blessings."

Masatora Yagami Gaiva's number two. A young man with gray hair. Calm, collected, and possessing excellent analytical skills, he is a serious individual who serves as the organization's brain. He uses knives in combat. Although he holds the position of number two, he is effectively on equal footing with Sanada, and they speak to each other casually. "Yokohama has become a land of warring states."
