good fanfic, regrettably, the only Bleach/Kill La Kill fanfiction. Period. EDIT- until 6/9/2014
Involves a realistic plot advancement that involves most of the Karakura adult characters, including an "affair" with Isshin and Ragyo.
Right there, one can tell that this fanfiction is pushing a ton of original ideas. Combined with a liberal amount of Nui Forth Wall Breaking, Kamui Adaptation, and a decent novel length, this fanfiction is a well recommended read on a night where you have nothing else to do.
Granted, by the length, it may take more than one night.
