later.

Chang Xia used the hoarded wild vegetables to farm and feed the entire tribe; she built houses and roads, so that the tribe would no longer suffer from cold and freezing; she also conquered the entire ancient continent with delicious food.

As the two are confused over their memories and personality fusing together, Rio (Haruto) decides to live in this new world.

Along with Haruto’s memories, Rio awakens an unknown but special power. If he’s to use it, it looks as if he can live a better life, but before that, Rio encountered a kidnapping which results in involving the two princesses of the Bertam Kingdom.
