◇The following contains spoilers.

In the second episode, Takagi finds himself embroiled in a serial murder case targeting six people who are hated by his former classmate Sonoko (Araki). He teams up with Sonoko to uncover the truth behind the murders. The victims, Takeda (Mizukawa Katamari) and Sakurai (Kudo Asuka), are attacked in a manner that resembles a "picture of their future dreams" that they drew 22 years ago. Takagi is horrified by Sonoko's words, "Someone in this class hates you. Someone other than me."

Takagi and Sonoko contact one of the six, Nakajima Emi (Matsui Rena), to warn them of the danger. Emi's dream was to become an idol, and she had been drawing "pictures of idols in the spotlight." Emi, who was working as a hostess in Roppongi, Tokyo, apologizes to Sonoko when they meet again. Emi had once stolen Sonoko's matching keychain, and bullied her when she became suspicious. Sonoko becomes angry at Emi, who has not changed since they were children, and gets up from her seat...and so the story unfolds.

Later in the episode, Koyama, the president of app developer "TURBO inc.", is shown visiting Sakurai, who is hospitalized. Koyama walks down the hospital corridor humming "The Bear in the Forest" and tries to open the door to Sakurai's hospital room, but a nurse tells him that visitors are not allowed, so he leaves. Then, towards the end of the episode, he visits Takagi's house and chats with him. When Takagi asks Koyama, who had started a company in the US, "How long have you been in Japan?" Koyama replies, "Just recently. I had a press conference here about a new business venture, so I came back to Japan for the first time in a while."

Koyama, who says he heard everything about the reunion and Takeda from Sakurai, suddenly begins singing a parody song he wrote in elementary school: "Aruhin-chan, Mori no Kantaro, Kuma-san Nico-chan, dea-ta-bo, Hanasaku Mori no Michonmage, Kuma-san dea-ta-ka-king!" After Koyama returns home, Takagi realizes that the parody song has changed the order in which the six people will be killed, and hurriedly tells Sonoko that Emi will be the next target, but Emi is pushed away by someone and hit by a truck passing by on the road.

On social media, many voices expressed suspicion about Koyama, who suddenly returned to Japan and appeared in front of Takagi. Comments included, "Turbo is suspicious," "No matter how you look at it, there's something dark about him," "I'm starting to see Turbo as an accomplice or collaborator with the perpetrator," "Turbo is cool, but he's always been suspicious!", "I wonder if he's trying to look like he's up to something or what," and "No matter how many times I see Turbo's smile, it's scary."
