To Whom Does the Name Belong?

Following the stand-ins concert, Kanata, Mimori and the 77th gen understudies are asked to stand in for a guerilla concert on a planet where the entertainment ban is in full effect, prompting some jealousy from the 76th gen understudies. Meanwhile, Minami is still concerned about what she saw the other day, and acts weird around Kanata. As they make over there, Sae Miyazawa, a former 76th gen understudy, grows concerned about Megumi. As the increased security evokes debate about whether the concert should be cancelled, the ship comes under attack by the DES. Noticing Minami is struggling to stay focused, Yūko and Kanata set off to rescue her as she is overwhelmed by the enemy. As she recovers from her injuries, Minami laments that she does not want to graduate, but she does not want to hold Kanata back either. As Yūko tells Minami that she should focus on her dream above others, Kanata resolves to become stronger.
