The Shinobi World

Genbu is a colossal tortoise that serves as a living island, its shell covered in lush vegetation and small ecosystems. It drifts slowly off the coast of the land of lightning, providing shelter and sustenance to various creatures and adventurers who dare to explore its back.

Genbu's massive shell resembles a verdant landscape, with trees, shrubs, and even small waterfalls cascading down its sides. The tortoise's eyes are wise and ancient, reflecting the deep knowledge of the ages.
