Zang Yanzhi: "...???" Note: Since I can't write about the Onmyoji game, abilities are based on monster legends. These are my own creations, so please don't nitpick. Note: Each world's secret identity isn't limited to one monster's abilities. The monster named in the blurb is the hero's current form. Note: Mostly my own headcanon, with the original work as a secondary reference. Note: The whole story is about brotherly affection, no romance. Note: The author's knowledge of sports comes from anime, guidebooks, and so on. This is fanfiction, so please don't make meaningless comparisons with reality. Theme: Always move forward bravely, no matter what
