Seishuu's mother is really against him going back to the island. While he was in a discussion with his mother he finds out that his father also used to live on the island. After their discussion Seishuu's mother brought Seishuu a box send by the gang. After she saw how delighted Seishuu looked she finally agreed to let him go back to the island.
When he arrives back at the island, everybody surprised him. He also got a call from Kawafuji saying he got fifth place, but he wasn't sad about it since it was a work he could be proud of.
