Uchuu Kyoudai

Synopsis

It is revealed that Hibito was able to be saved because of Azuma's plea to NASA to take into account Mutta's theory as the worst-case scenario and send the Brian drone over to where he suggested. Meanwhile, Mutta is relieved to hear of Hibito's safety once news reaches JAXA. Whilst the other astronauts, Freddy Saturn and Buddy Walters, bring Hibito and Damian back to base, they reminisce about all the things Brian taught them. Three days later, Mutta gets a chance to talk with Hibito, who gives him his deepest thanks for helping to save him, promising that they'll both stand on the moon together.
