Boro lived in a giant rotten tree. One day, the tree collapsed and crushed a creature to death.

Since then, Boro has been walking through the forest to commemorate the creature and the home he loved.

He fell many times and scraped his knees many times. On his 252nd lap through the forest, Boro passed by Kuu.

A bud from the giant tree he once loved was growing on Kuu’s head, but he didn’t notice.
