Atom's memories come back to life and he returns to Ochanomizu, but Tenma persistently pursues him. Finally, he decides to take aggressive measures. He uses a robot dog to take over the Ministry of Science. Having taken over the Ministry, Tenma has one request: to talk to Atom alone. In Tenma's hand is a bomb that will blow up the Ministry. Alone at the Ministry, Atom finally confronts Tenma. The location is Plant 7. For Tenma, it was the place where he had a history with his son Tobio. Gradually, the secret of why Tenma abandoned Atom, whom he created in place of his son, is uncovered, along with Tenma's sorrow and despair. In a fit of insanity, Tenma reveals everything, raises the temperature of the blast furnace, and tries to end the life of the Ministry of Science as well. At Plant 7, which is on the verge of exploding, Tenma tells Atom to go. Atom is forced to make a bitter choice. (Source: Wikipedia)
