Reluctantly, Akane is transported to April, a vibrant and magical realm facing ecological collapse due to the disappearance of its natural resources.

In April, Akane meets a diverse cast of characters, including Hippocrates, a self-proclaimed genius inventor, and Pipo, a small, bird-like creature who serves as her guide.

From traversing treacherous landscapes to confronting the enigmatic forces threatening the realm, Akane and her companions must rely on their ingenuity and teamwork. The story culminates in a climactic confrontation that tests Akane's resolve and underscores the interconnectedness of all living things.
