Crimson Scars

The shinigami had lost hope- they had all resigned themselves to their fates: they were going to die. And they did. That was until a certain captain-turned-shopkeeper created the impossible, and sent Kurosaki Ichigo back in time to attend the Shin'o Academy and stop Aizen before any of the Winter and Blood Wars happened. May add pairings later, spoilers for the manga. {Time Travel}
