[Prince of Tennis + Children Who Chase Lost Voices] Crimson

I came from Agartha, hoping to see the starry sky, and hoping to see you. (The whole story is drafted. I'll post the opening as a short story, then put up the whole thing once it's finished.) This is related to an obscure anime, so be sure to watch Children Who Chase Lost Voices before reading, or you won't understand some of the details. The male lead is tentatively Fuji (I've finally decided to go for it!). That may change. Note: There is a secondary couple, Kokona. Writing this for love. Theme: Strive to pursue what you want.
