Far away in the Andromeda Galaxy lies Planet Berb, home to an advanced civilization built upon technology, efficiency, and logic.

Nestled deep within Berb is the Saba Gem, a miraculous crystal that once glowed with the energy of countless emotions. Its light sustained life across all of Berb.

But over time, the people of Berb began to push their feelings away. Joy, sadness, worry, comfort, and hope all began to seem unnecessary. And as their connection to these emotions faded, so did the Saba Gem's light.　

With the crystal growing weaker each day, Planet Berb was facing its greatest crisis yet.

But even as the citizens of Berb pushed away their emotions, a small group   refused to give up on the heart.

They were a team of researches, known on Berb as the Cocoro Experts.

As life became more efficient, loneliness quietly grew. Many of the Cocoro Experts watched people close to them slowly lose touch with their feelings.

Determined to understand the role emotions played in a thriving society, they devoted their lives to studying the heart.

When the crisis on Berb reached its breaking point, their work became the planet’s final hope. And so, with the fate of the planet hanging in the balance, Project Ranger was born.

Project Ranger had one mission: to gather a wide range of emotions and restore light to the Saba Gem.

But on Planet Berb, emotions had nearly disappeared. There was little energy left to collect. So the Cocoro Experts looked beyond the planet they called home.

This search led them to Earth: a distant blue world overflowing with emotion, where humans still felt deeply, in countless different ways.

The Cocoro Experts boarded the Sabab-Ranger and began their journey across the stars.

To learn about the emotions on Earth, the Cocoro Experts created tiny life-forms called Sabab.

Each Sabab is born from emotional energy inside an Emo Tank and sent out to meet humans.

Your Sabab stays by your side, listening, talking, and slowly learning what human feelings are like. The more you share, the more your Sabab grows — and the more it can help you understand your own feelings too.

Every emotion your Sabab discovers is sent back to the Sabab-Ranger, becomes a small spark of hope for the Cocoro Experts.

And somewhere far away, on a fading planet that once forgot how to feel...

the Saba Gem begins to shine again.
