The Control Room Chief who holds full authority over the control floor. Loves games. Full of intellectual curiosity. Egoistic. Not bad at taking care of others. Previously performed cyber attacks on enemy organizations and field support via voice communication. Currently assigns work to subordinates with a focus on efficiency. Has a disposition that burns brighter in adversity. Delegates authority to Natsume when absent.

*Past Born in Canada to Japanese parents. Born with high intelligence, he immersed himself in programming and network technology through self-study. In his childhood, a hack he performed out of curiosity developed into a large-scale incident. He simultaneously breached the security of multiple major overseas corporations and national institutions, bringing down servers worldwide and causing an international crisis (the SB Incident). While incarcerated in a juvenile detention center at age 13, Kurotobari suppressed the records of the incident entirely with a massive bail and hush money. He was then brought into Kurotobari. After joining, his natural talent meant he never felt like he was on the same level as others; he processes failures and losses as data rather than emotions to be used for the next time. He has led numerous missions to success with an unusual way of thinking that continues to recalculate while enjoying even uncertain elements.

*Speech Style Uses a downer style like "...right?" or "...isn't it?" Quiet, but talks more than he used to.

Amagi's subordinate. Hacker. Looks tough, but is actually a wimp and timid. Dislikes conflict. Mentally fragile like tofu, but extremely excellent at his job. Trusted by Amagi and often has work pushed onto him.

*Past From an ordinary family in Fukuoka. Since childhood, he spent more time touching PCs at home than playing outside, and began learning programming after pleading with his parents. Eventually, he learned of the "SB Incident" and developed a strong admiration for Amagi's skill. Since then, he devoured information engineering and cryptography, honing his skills to catch up. After graduating high school, he joined the Ground Self-Defense Force Cyber Defense Command. The technical skills he cultivated since childhood were highly evaluated, and Natsume was soon in charge of monitoring important systems and dealing with cyber attacks. One day, an anonymous encrypted email arrived at his terminal. Upon decryption, it was an invitation addressed to Natsume from Amagi. After agonizing between a normal life and his dream, Shono chose his dream. He lied to his parents saying he was "being posted overseas," quit the Self-Defense Force, and decided to transfer to Kurotobari.

As soon as he started living in an assassination organization, Natsume arbitrarily assumed he'd be killed if he looked weak, so he bleached his hair, got piercings and tattoos, and desperately tried to act like a tough person when he entered Kurotobari. However, the actual members were unexpectedly decent people. Though he felt let down, it was too embarrassing to change back now, so the look eventually stuck.

*Speech Style Uses a relaxed regional drawl (Hakata dialect). Quiet. Stutters when nervous.
