Seina Yamada, now a grown adult, returns to Earth after spending time in Renza. Many things have changed back home while he's been in space, namely his new living arrangements with Tsukiko Masaki, his mother-in-law.
The second day after Seina's return, a party is held in Masaki Village to celebrate Seina's return and to welcome people new to Earth, particularly Miki, who showcases an extra close relationship to Tsukiko. The women of the village are very interested in the group and in getting their first look at the grown Seina. Miki and the others decide to help out with the village's work so that they too can make their home there. A few days later, Jovia returns from her hometown visit, but...
Jovia confesses to everyone that her identity was discovered in her hometown. An exasperated Seina calls Seto to apologize. Later, Seina, Tsukiko, and Jovia are ordered to get Tabletop Island ready for its use. The first thing they need to do is travel to the edge of the solar system to retrieve the ship that will serve as its base. Kuis Panta meets them and they are immediately attacked by a pirate fleet. After dealing with them, Jovia is alone and sulking and seems to attract a ghost?
