Energy, Spirit
You're looking for a treasure, but no normal treasure... a treasure that's a stash of energy. Not gold, money, or anything like that. Imagine yourself finding it, and opening up a treasure chest. Out bursts a spirit ball of energy like you've never seen.
Try to touch the energy spirit, it's pretty amazing. Is it solid? Does it shock you? What does it feel like? Be sure to imagine it out.

As you reach inside the energy spirit, you feel something hard inside. It's a large key (き) that gives you access to another treasure.
You take the key and open another treasure that's nearby. Open it up and see what's inside. Imagine something spectacular.
