Haikawa Juzo was arrested on suspicion of killing 13 children and hanged himself in a detention center.Detective Saiki Jin believes that Haikawa's actions are likely to protect the “real murderer”.

Saeki investigates alone and goes to the place where Rensui Kanon was pushed down.During the visit, it was discovered that during the time of the accident, there was a man with injuries on his face“...

On the other hand, headed by Kanon, the surviving children - Sosuke, Maya, Satoru, and Yuma gathered at Haikawa's house.

”It was the father who killed the children. It was impossible to imagine“. Hanayin looked at the expressions of the four people as if nothing had happened...

Regarding the ”real murderer“, Satoru mentioned the name of Kenryu whose whereabouts are still unknown. Kanon saw the ”Rika“ tattoo on Maya's back and recalled a certain memory” at the Haigawa mansion.

Then, the other children left, and Cangyou stayed there alone——

2024.Reporter Touko Mori is very concerned about the fact that the missing runaway girl Meira has “Rika”'s mark on her wrist.I'm thinking that this might have something to do with one of the children who survived the Haikawa Rei incident?
