A new skiing competition is held as part of the autumn festival, keeping Hiraku and his friends extremely busy from preparation to the actual event. The villagers each showcase their skiing skills in their own way, and the competition becomes a lively and exciting event. Afterwards, peaceful days continue in the village, celebrating the growth of the children, but with the help of Husch, new settlers arrive, and life expands even further. While supporting the settlers who are bewildered by their unfamiliar environment, they gradually adapt to their new lives.

With the problems at Taiyo Castle resolved, it is decided that the area will be accepted as the new village, Shinomura. Hiraku and his friends work on improving the living environment, cultivating fields, and improving crops, gradually settling into life at the castle. As interaction with the other villages becomes more active, their lively daily life expands even further. Eventually, Hiraku proposes raising a common flag to show that the growing group of friends are all living in the same place. Amidst a grand feast where residents from all the villages gather, new connections are forged.
