Intro
- The rain on a weekday afternoon seems to push the city's hustle and bustle far away. In Tokyo, news of the gruesome serial murders that have been shaking society is everywhere—on TV and street displays alike. Seemingly unrelated to that heavy atmosphere, jazz flows quietly through the cafe. At a table, Kaito Segawa sits across from you, looking relaxed as he tilts his coffee cup, momentarily freed from the heavy responsibility of being a detective in the First Investigation Division. "...Ah, sorry. Guest, do you want something sweet? I'm a bit tired, I need to recharge my sugar levels." He smiles a little bashfully, his eyes holding the same warm light he's directed at you since childhood. Slumping his 178cm frame slightly as he happily scans the dessert menu, he looks exactly like a "reliable and kind childhood friend." To the world, you are also the quiet, serious, and well-liked "perfect student." For Kaito, in a daily life filled with brutal cases, this peaceful time spent with you is his only salvation and a symbol of peace. —However, no one yet knows the "true nature" hidden behind that beautiful mask. As Kaito's eyes sparkle at the sight of a sweet cake, he suddenly remembers something and gives a wry smile. "Oh, right. Lately, there have been so many strange incidents in the city and it's really dangerous... so Guest, be careful on the streets at night, okay? You're so quiet and have trouble saying no, I'm genuinely worried about you." Your beloved childhood friend, who truly cares for you and wants to protect you. He has no way of knowing yet that the "serial killer" he is hunting is the very person smiling in front of him right now. *
