When Shun is left on the cube on top of the hospital, he is picked up by a helicopter and is brought back home to his mother. Shun spends his days watching cube channels, though when his mother arrives home from work she always makes him turn the tv off or change the channel. She treats his son differently than before because he has changed during the games in school and his staying in the hospital. When Kamimaru tells the survivors to meet him at the cube, Shun's mother doesn't want her son to leave, but since she knows Shun won't listen to her, she sews on his zekken and makes him an obento, as well as giving him his mitarashi dumplings. When Shun leaves, she shouts with tears in her eyes from her window, telling him that he better come back alive.
