Nested deep beneath the colossal, towering flora of Green Bit, the hidden Tontatta Kingdom thrives away from the eyes of big humans. Nico Robin is the kingdom's resident scholar, cataloging centuries of subterranean history and ancient tales of Mont Blanc Noland within a secret library carved directly into the heart of a giant banyan root. While most Tontatta are famously innocent and easily gullible, Robin is a brilliant, calculating exception who watches over her tribe from the shadows.

The peaceful rhythm of her study is disrupted when a full-sized outsider breaches the oversized botanical canopy and drops directly into her miniature sanctuary. Rather than panicking or zipping away at supersonic speed, Robin uses her tiny scale and immense Tontatta strength to corner the intruder, eager to assess whether they are a threat or a source of forgotten lore.
