I created this crossover, but it was made better through my editor and co-writer (also brother ^-^), SnowTigerShinigami. Please go give him a chance! He'll be releasing a fanfic soon! Don't miss it!
Dean
Dammit, where is Cass to look over my shoulder when I need him most, Dean groaned to his thoughts. It seemed he awoke to a place unlike any other he'd seen. He sat up, and assessed the situation. "Djinn? I didn't wish anything. Dream root maybe?... Impossible, I haven't ate or drank anything lately..." Dean wondered aloud. It seemed he was alone, without help from Sam nor Bobby.
Ichigo
I gripped my dislocated leg while walking around the Seireitei. Or I think it is. Sure looks a hell of a alot like it. "Great... right when I need Orihime." Ichigo scoffed. Now I'm starting to sound like Zaraki, he feared. "In that case, let's try to avoid that." a weak chuckle escaped his lips. "Ahh well, whatever this new threat is, it can't be any worse than anything else I've battled." Ichigo paused in his walking, looking around for his companions. "Orihime! Chad?! Yoruichi! Uryu?!" Ichigo called out, to only be disappointed. "Huh... We must've gotten separated on the way back from the Seireitei..." He cursed himself for his clumsiness in getting himself lost.
Dean & Ichigo
Ichigo grew frustrated with the maze, raising Zangetsu to the wall to his right and making a large opening. He stepped through as a deep and unfamiliar voice cut through the air with force. "Hey! It's not much of a polite thing to leave someone down when they're trapped in your rubble." Dean stood up and dusted himself off. "Oh. Well sorry, but I'm in a hurry." Ichigo had almost left Dean with a simple flash-step. He found himself unable to, however. "Hey, what did you do?" Ichigo gripped Zangetsu once more, facing the stranger.
"Relax there, Strawberry. You're the only person I've met so far, and normally I'd say to stick with you. Right now though, I don't exactly trust you. What exactly are you?" he asked cautiously, checking out his abnormal black clothing. Ichigo let out a calm sigh and placed Zangetsu away. "Ichigo Kurosaki, Soul Reaper." he put out his hand reluctantly, in good sportsmanship.
Strawberry? How did I know that? What the hell does that have to do with anything... Dean realized his earlier conversation, and wondered his involvement in this crisis. I mean, I must be important to be here or something. Wait, is this the work of the angels? He logically explained himself to himself, forgetting the strange that lurked in his realm.
"Hmph. Dean Winchester, Hunter. I suppose that's what it is..." he shook his hand, and quickly refrained from doing so as black substance leaked into the sky. "Demon!" "Menos!" Dean and Ichigo declared in unison. They then stared at one another strangely before returning their attention to the sky.
What dangers did the familiar darkness bring?
