Kakunte Tribe

The Kakunte Tribe (カクンテ人, Kakunte Hito) are a race of mysterious and minuscule people who reside at Mushroom Forest. They have their own language, Kakuntean, and due to where they live their main source of nutrients is mushrooms. They also worship Tottoteruri, who was killed by Hero before the protagonist's appearance.

Hint
The Kakunte by the door is hurt. Perhaps you can help it recover?
