"This is a tale that took place long ago. There once lived an old man and an old woman. The old man went into the woods to cut down some grass and the old woman went to the river to... (You know the rest.) The ogres had finally been defeated, but apparently, there were more ogres living elsewhere, so Peach Boy crossed the sea... It was an amazing feat to defeat the ogres and a joyous feat that Peach Boy saved many lives. But the one thing that went wrong... Was that they had fun. This is nothing more than a "What if"... What if there was more than one peach that tumbled down the river?
Sally meets the demihuman Frau, who immediately joins her on her journey. After experiencing the discrimination that demihumans face at the hands of humans, Sally and Frau are arrested by Hawthorn, commander of the Knights of Rimdarl!
Sally and her companions arrive in a village plagued by vampire attacks... and demihuman discrimination. When Sally refuses, at Carrot's urging, to punish the humans for their treatment of Frau, Carrot decides to seek other aid... at the hands of the vampire himself!
In a world where man-eating ogres run rampant and the people hide in walled-in cities, Sally, princess of the Aldarake Kingdom, longs to go on a journey and see life on the outside. But Sally's life will change forever when a traveler named Mikoto comes to the kingdom... followed by an army of ogres!
Sumeragi holds a meeting to warn the other ogres of the path of destruction wrought by Mikoto. While the other ogres panic, the fighter Todoroki raises his doubts about Sumeragi's motivations... until Sumeragi reveals Meki's fate.
As Sally rushes to save her companions, Frau fights Basoo, and Carrot struggles to deal with her former ally, Shinki. Hawthorn is prepared to die to hold off Todoroki. Can someone save him in the nick of time?

The Kingdom of Rimdarl is destroyed by Somenki's cannon, leaving Hawthorn adrift. He and Meki (now Carrot) join up with her, but in the next town they visit, Sally begins to wonder about the nature of prejudice.

During the battle with Juki, Sally declares that everyone present should try to make peace. Meanwhile, Sumeragi makes a case to Mikoto about coexistence between ogres and humans.
