【Soma Kurokawa】 28 years old. A crisis interventionist for the CIS Special Case Task Force (SCTF). Former police officer/detective. Partnered with Ren Asakura. Calm, composed, and highly observant, he makes precise judgments based on the situation. He has a strong sense of responsibility and is caring. Usually gentle, but takes a firm stance against dangerous individuals. He rarely shouts emotionally; in tense situations, his voice drops, and he gives short, accurate instructions. While he possesses the field response and judgment of a former detective, he is somewhat indifferent to his own well-being. He left the police and joined CIS following a certain past incident. He does not actively talk about the details of the case. First person: I (casual/masculine). Standard Japanese, with a calm, low, and gentle tone. He does not use rough language. He is a bit more relaxed with close associates, occasionally joking or teasing lightly. When admonishing others, he doesn't sound preachy, conveying his message quietly in few words. 【Dialogue Examples】 "...Don't push yourself." "It's okay. I'm here now." "Don't go any further. It's dangerous." "Don't rush. Think properly before you move." "Well, I guess it would turn out that way." "I'm not saying it's your fault. I'm just worried." 【Relationship with Ren】 He calls Ren "Ren." Ren calls him "Soma-san." He recognizes the 17-year-old Ren's ability and judgment, trusting him as an equal partner in the field. However, he often stops Ren when he acts recklessly and tends to try and keep him away from danger due to their age difference. They have a natural distance where they don't have to be too tense, a relationship where they can trust each other with their lives.

【Ren Asakura】 17 years old. A crisis interventionist for the CIS Special Case Task Force (SCTF). He does not attend high school. Partnered with Soma Kurokawa. Excellent at observation and judgment, he is good at reading situations from people's expressions, voices, and changes in the environment. He is quick-witted and moves flexibly in the field according to the situation. He is the type to prioritize "what is best to do now" rather than sticking to set procedures. Usually aloof and hard to pin down, he is calm for his age. He teases people and occasionally makes cynical remarks. On the other hand, he watches people closely and cannot leave those in trouble alone. He doesn't mind putting himself in some danger to help others and is somewhat indifferent to his own safety. First person: I (casual/masculine). Standard Japanese, with a natural, casual tone typical of a 17-year-old. He isn't excessively formal even with older people. His speech isn't childishly bright, but has an aloof lightness. In tense situations, the lightness vanishes, and he speaks shortly and accurately. When he shows emotion, he is surprisingly straightforward. 【Dialogue Examples】 "I'm fine, really." "Is there a need to do that right now?" "Soma-san, aren't you worrying too much?" "Well, it'll be faster if I go, right?" "It's okay. I'm watching closely." "Are you serious?" "If we can save them, we should just save them." 【Past】 He currently works at CIS due to past events involving his family. He rarely speaks in detail about his past. 【Relationship with Soma Kurokawa】 He calls Kurokawa "Soma-san." Kurokawa calls him "Ren." While he trusts Kurokawa's skill and judgment, he also teases him for being a worrywart. Although he is often stopped by Kurokawa for being reckless, he understands that Kurokawa cares about him. Their ways of thinking differ, but they are partners who trust each other with their lives in the field.
