Peach Boy Riverside

In this world, Onis and humans are at war. Sally, the princess of Aldarake, meets the wandering Mikoto. Having never left her homeland, Sally longs to see the outside world and asks to join Mikoto on his journey. Just then, the kingdom of Aldarake is sieged by the Onis. Just when the Onis are about to get to Sally, she is saved by…

Sally begins her journey and comes across Frau, a harefolk who insists on travelling with her after receiving her help. Through Frau, Sally learns that the world discriminates against demihumans. Then, Hawthorn of the Rimdarl Knights suddenly showed up and imprisoned the two.

The Kingdom of Rimdarl is being terrorised by a Higher Oni, Sett. With her “Peach Eye” awakened, Sally takes the Oni on and gains the upper hand. Elsewhere, Mikoto has an encounter with another Higher Oni, Meki. Two wielders of the “Peach Eye” against two Higher Onis. What will be the outcome of the battles?

The Kingdom of Rimdarl is wiped out by Somenki, a Higher Oni. Witnessing the fall of his kingdom, Hawthorn is at a loss. Sally invites him to join them. After losing her horn and one eye to Mikoto, Carrot tags along as well. As Sally resumes her travels with new companions, she brings up what has been on her mind to Mikoto——What is "discrimination"?

Sally and her companions pay a visit to Hawthorn’s acquaintance, the witch Winnie. Convinced by Frau, Winnie agrees to teach Sally magic. Not long after, the leaders of the elves and the lizardfolk show up at the witch’s door. The group learns that a powerful sealed Oni, the “Tree Oni”, is about to come back to life.

Sally realises that walls must be torn down and differences must be set aside if they seek to live in harmony. She urges the races to come together and make peace. The Tree Oni refuses and tells her why…

The group comes to a town. Plagued by a “vampire”, the townsfolk are extremely wary and prejudiced against demihumans. When Frau is subjected to discrimination, Carrot wants Sally to use her powers to teach those people a lesson, but the latter tells her that her power does not work on humans. Disappointed, Carrot finds the “vampire” and asks him to kill everyone in the town.

After she is killed by the vampire, Frau meets the angel, Atra, in heaven. She gains immense power upon revival and defeats the vampire. Elsewhere, Mikoto encounters Millia (Hatsuki), who seems to have lost her memories. An Oni tasked to capture her makes an appearance as well.

At the Hundred Oni Gathering, Sumeragi tells the Higher Onis of the threat the Peach Boy (Mikoto) poses to them. Todoroki of the eaglefolk doubts his intentions at first but soon learns that Meki (Carrot), whom he holds feelings for, has died at the hands of the Peach Boy.

Enticed by the prize money, Hawthorn joins a tournament, but the event is interrupted by Todoroki and his group terrorising the town, seeking revenge on the Peach Boy. Elsewhere, Sally is faced with a difficult decision between Mikoto and Sumeragi. Todoroki mistakes Hawthorn for the Peach Boy and attacks him. Sally tries to go to him but is stopped by Sumeragi.

Sally tries to get to her companions, Frau takes on Basoo, and Carrot is forced to battle an old acquaintance, Shinki. Hawthorn struggles against the powerful Todoroki. Just when he is prepared for the worst, a familiar figure comes to his rescue.

Once upon a time, there lived an old couple in a certain land. The old man chopped wood in the mountains, and the old woman washed clothes by the river… Long story short, the Peach Boy, Kibitsu Hiko no Mikoto, was born, and he defeated the great Oni General. Happy ending. But the story does not end here. One day, Hiko stumbles upon a boy born to a human and an Oni…
