Migi appears on Shinichi’s dreams and bids farewell to him. As he is about to vanish, he thanks Shinichi and asks him to forget about their memories. But contrary to what Migi expected, Shinichi still clearly remembers everything about Migi, and he continues to think of him even after his life has returned to normal. There has been no notable parasite activity so far and the world has generally become more peaceful, too.
A year after, Shinichi meets Satomi as he tries to catch up with his studies. While strolling around, he catches a glimpse of Uragami so he tries to chase him. However, the serial killer manages to take hostage of Satomi and brings her on the rooftop of a building where he kills two other strangers. Shinichi finally comes face to face with Uragami and tries to save his girlfriend by attacking the criminal. He gets his arm stabbed in the process but he manages to land a critical blow on the enemy. However, Satomi gets pushed down the building and Shinichi cannot reach her on time.
Just when he starts to lament, Migi appears in his head and tells him that he is already tired of holding Satomi. When Shinichi looks down, he realizes that his right hand is clutching Satomi so he pulls her up to safety. As the episode comes to its end, Shinichi looks up at the sky and recaptures the moments and lessons he’s learned in his life through his experiences.
