On the roof of a building in Shinjuku, a girl (Ayana Shiramoto) jumped to her death.Nothing was found at the scene to prove her identity, but judging from her landmine makeup and clothing style, she was probably wandering outside.If she ran away from home during her lifetime, her family may be anxiously looking for her... In order to track down possible clues to her identity, Sakura (Koshiba Fuka) and Makoto (Oshima Yuko) hold the drawings of Muto (Hankai Ichika)Portraits, stepping into Shinjuku Kabukicho.

However, the children here had a strong dislike for JC, and when Sakura and Zhen tried to communicate with them, they received only indifferent responses.The only discovery during the investigation was that the deceased girl was called 'ki-chan' in the group.As for her real name and contact details, no one seems to know - such anonymity is considered the 'norm' here.

During further investigation, Sakura Kazuma met Harpi (Riko) who was close to Ki-chan, a girl who also wore mine makeup and a mask.They hoped to check Ki-chan's phone, but Harpi refused to cooperate, saying 'that's impossible'.Harpi firmly opposed returning Ki's remains to his family and revealed: 'Ki-chan doesn't want to go home, she definitely doesn't want to go back'.Then he stopped talking.In order to have an in-depth communication with Harpi, Sakura made up her mind, so she appeared in Kabukicho with mine makeup!

Why did the girl who was still laughing yesterday choose such a sad ending?Sakura Kazuma works tirelessly to reveal the truth!At the same time, in the consultation room of the unidentified person, a strange atmosphere quietly spread——"
