My Shadow Has Disappeared

That day, a red bolt of lightning struck my home. In my haste to get back, I was caught in a serious car accident.

I was fine, but my shadow had disappeared?

Then I met a man wearing a demon mask, and my shadow returned. It could move, block attacks, strike, and strengthen my body.

The masked man said, "I am a legendary Shadow Envoy."

And my mother was the White Shadow Envoy a hundred years ago.

But I think there's... something wrong with my shadow.
