Kon no Ki Konoha

Only during autumn, a mysterious boy can be found on a small mountain. Like the tree he dwells inside, the tall, young man has dark blue hair and a calming presence. As luck would have it, a little girl named Akino stumbles into him. The boy tells her his name, Konoha, and shares with her that he is a tree spirit with an intangible body.

Soon enough, a pure and unique bond forms between the two. Every year during autumn, Akino comes to the mountain and stands in front of the tree, reuniting with Konoha after a seemingly endless wait. However, despite their unshakable love for one another, fate may not be as kind as they are hoping.
