Ramune Monkey
Three former middle school friends who reunited after 37 years to pursue the mystery behind their former club advisor's disappearance.
Three men who loved making kung fu movies while at junior high reunite. However, they realize they have hazy memories about their beloved advisor.
Having found a pen identical to Matilda’s at the construction site, Yuta and the others go to the police and insist they open a murder investigation.
Yuta and his friends relay Akari’s important testimony to Officer Tsurumi. At the café with Hakuba, they recall what led them to make their own movie.
Yuta and the others have learned that Matilda was being stalked. Kisuke, who takes care of his mother, is encouraged to draw comics again.
As Yuta prepares his defense against bribery charges, he, Hajime, and Kisuke learn new information about the criminal past of Video Jupiter’s manager.
Yuta crashes at Hajime’s apartment. Hajime identifies a man they used to call Rambo in an old video while investigating Matilda’s disappearance.
Hoping to learn more about what happened to Rambo, Yuta and his friends decide to pay a visit to someone who knew Hisao Torikai back in 1988.
Enjoying a quiet New Year’s Eve at the café together, Yuta, Hajime, and Kisuke think back to Matilda’s disappearance on the same date 37 years earlier.
As the group tries to make sense of a note found with the No. 12 videotape, Yuta gets an urgent message from Emi urging him to come home right away.
Yuta’s group barges into Kagami’s home to confront him about the murders. Kento says that Matilda brought a different tape on the day of the deadline.
Matilda descends from a UFO and restores Yuta and his friends’ memories. Later, Yuta tells his brother about the doubt that had been nagging at him.
