Science Ninja Team Gatchaman - Season 1 Episode 4 Revenge on the Mecha Mechadegon
8.40 30 minutes During the investigation of an incident, Ken visits the Institute for Earthquake Research. Because of an earthquake caused by a mecha, he falls along with the director of the institute, into a crevice in the earth. Ken transmutes and is saved, but he cannot rescue the director.
Ken stands before the director's grave and is attacked by the director's daughter Naomi, who firmly believes he's Galactor. Ken understands her anger at not being able to avenge her father and decides to let her know about his true identity as member of the Science Ninja Team. Consequently, he lets her join the team on the mission.
In an investigation it has been calculated which resources the mecha will most likely attack next, and the God Phoenix encounters the mecha there. Inside, Ken wants to let Naomi avenge her father and asks Nambu for permission to fire the bird missiles. Nambu doesn't give permission, but Ken ignores him and tells Naomi to fire the bird missiles anyway.
Naomi hesitates to press the firing button, and Ken takes Naomi's hand and makes her fire the missiles.
At the director's grave, Ken hands his bracelet to Nambu. He says he wants to take the responsibility for making Naomi press the firing button without permission and resign from the team. However, Nambu says that Ken is needed for world peace and Naomi promises not to reveal his true identity.
