I finally announce my first-made fanfic battle spirits story. (which will be irregularly released, and subject to the comments and reviews)
Background: This story is a fanfic side-story with the anime Battle Spirits Burning Soul. With Yukimura and Friends still being the protagonist, but revolves with a war of the other dimension.
