Staring Experiment (お見合い実験, O miai jikken) is the 49th chapter of the Kiseijuu manga series, written and illustrated by Hitoshi Iwaaki.
With Reiko dead, the police take her child into custody, and bring Shinichi in for more investigation. In a police interogation room, an experiment started by Detective Hirama, will be taking place. A serial killer named Uragami will be screening five people, including Shinichi, to see if they're a parasite or have the ability to sense the creatures. After screening the other four people, who all failed, Shinichi is brought in and sat adjacent from Uragami. Though Uragami joked about Shinichi even being here, he quickly changed his demeanor, and asked that the boy looked him right in the eyes.
