The manga recounts the story of another "peach" beyond the well-known Momotarō the Peach Boy of Japanese folklore. Kodansha Comics is releasing the manga in English, and it describes the story: Sartrienne Aldraic, princess of the Kingdom of Aldraic, dreams of traveling the world—a dangerous dream in a land where monsters roam the countryside as they please, and humans live behind high, strong walls. But when a chance meeting with traveler Mikoto gives hope to her dream, he shatters it soon after, as he reveals himself to be none other than Momotaro, ruthless demon-slayer. Though horrified by the gore Momotaro leaves behind, Sartrienne is convinced more than ever that she needs to learn about the world beyond her walls, and journeys out...following the steps of the mysterious, charismatic, terrifying boy she met that day...
