Black and White Unwanted Adventure

Ichigo can't seem to catch a break. Just when he'd defeated Aizen and was ready to lose his powers, he gets sucked into another world, turned into a kid. Not just that, he'd been separated from both Zangetsu, and his inner Hollow. With no way home, he might as well look out for a trouble-prone kid named Ash on his journey with Hichigo. NO PAIRINGS. Rated T just in case.
