A toy robot and two kids get pulled into Old Testament stories the moment they open a talking Bible. The show treats these ancient narratives like adventure zones to explore, not lessons to sit through. Zenmaijikake's there making jokes while Sho and Azusa actually live through the moments that built the faith millions hold now. The magic isn't in the theological weight, it's in watching children discover why these stories still matter because they're standing inside them. You're not getting a Sunday school retelling. You're getting time travel into the exact moment a shepherd becomes the one who stops a giant, or a boat becomes the only thing between a family and the end of the world.
Sho discovers a mysterious talking book hidden in his home that holds an extraordinary secret: the power to transport him backward through time. When his friend Azusa and his mechanical companion Zenmaijikake touch the book, all three are pulled into the ancient world, arriving at pivotal moments from Biblical history. Each jump sends them into situations where they witness foundational events firsthand, encountering figures and stories that shaped religious tradition. As they travel through these distant eras, the trio must navigate unfamiliar lands, survive dangerous circumstances, and understand the significance of what unfolds around them. The book serves as both their guide and anchor, appearing when they need it most. What begins as curiosity transforms into genuine adventure as Sho and Azusa grasp the weight of history. The series balances educational discovery with genuine wonder, letting viewers experience these classic narratives through the eyes of modern children encountering them for the first time. Each episode sends the group somewhere new, somewhere they never expected to go.
