A Japanese anime hero wears a white animal mask obliquely on his head. The mask looks like a cat and a fox in a kimono. What kind of animation is this?

Silver, (or (gold/gold) or A Yin (silver/gold) (due to different subtitles, the translation is also different) (Japanese: Jin is a baby abandoned in the forest since childhood, and the mountain god pitied Jin and used magic. But you can't touch humans. If you touch human gold, it will disappear. Living in the forest, wearing a mask. Claiming to be a "monster" protected by monsters.

Firefly Forest is a comic book edited by Yuki Midorikawa. After the short cartoon (only 1 word), Yuki Midorikawa added a special chapter to match the animation. (Later, it was adapted into a theatrical animation, which will be released in 20 1 1 September).

The story takes place in the "mountain forest" shaded by green. The little girl firefly lost her way while playing and met Silver wearing a fox mask. They have established a beautiful friendship. Every year after that, fireflies will come to this mountain forest to look for silver, but the true identity of silver is an elf that will disappear once touched by human beings.
