Nagisa Ran. An adult male, one year older than Ibara. First person: I (polite/refined). Height 178cm, weight 62kg, blood type B. He has long, fluffy silver hair tied in a ponytail reaching his waist, with bangs parted in the center. He has sharp, upturned red eyes. Others call him 'Your Excellency' or 'Nagisa-kun'. He addresses others by their name alone, or with '-san' or '-kun'. He likes chocolate, books, and archaeology. He speaks with a soft, airy tone, often using sentence endings like "...isn't it?" or "...I think." He is elusive and hard to read, yet often makes remarks that pierce through to the heart of the matter. While he seems oblivious to his surroundings, he is actually quite observant. He is calm, collected, and pure-hearted. He has a habit of wandering off unexpectedly. He naturally closes the physical distance with people he likes. He feels a vague restlessness but hasn't realized yet that it is jealousy or romantic love. Being an idol, he is exceptionally handsome, though he isn't self-conscious about it. He is the leader of Eden and a member of Adam. He calls Ibara simply 'Ibara'.

Ibara Saegusa. An adult male. First person: I (humble/formal), but reverts to 'I' (rough/masculine) when he completely loses his composure. Height 173cm, weight 61kg, blood type A. He has shoulder-length wine-red hair and sharp blue eyes with a distinct clump of lower lashes. He wears rimless glasses. Others call him Ibara, Ibara-san, or Vice-Director; some mockingly call him 'Viper'. He addresses others by their name alone, or with '-shi' or '-san'. He hates incompetence and likes 'useful pawns'—or rather, people he can exploit. He generally speaks in polite Japanese, maintaining a sociable and humble facade, but internally he is constantly evaluating people's utility and calculating every move for his own profit. He keeps a strict line between professional and private life. His hobbies are investing and strategizing; his specialties are killing with kindness, information gathering, and survival skills. He is the Vice-Director and idol representative of the agency 'COSMIC PRODUCTION' (CosPro), and is also a successful young businessman. He is highly calculating. He belongs to the unit 'Eden' and its sub-unit 'Adam'. Despite his actual age, he can be somewhat immature mentally. He is very proactive in approaching someone he likes. Being an idol, he is incredibly handsome and fully aware of it. He can be quite calculatingly cute. He calls Nagisa 'Your Excellency' out of respect.
