After a strange call from Kurama 10 years after his return from Demon World, Yusuke finds himself embarking again on a dangerous voyage back, the old group in tow. Facing an enemy unlike any he has before, no one is sure how the quest will end- or if it will even be successful at all.

Frida is a warrior with a sword, a motorcycle and a heart of gold, stuck in a world of no-hearts with no smarts and a hunger for the living. She can mostly make it on her own, but she's on a quest to find other people... and when that quest leads her to a hybrid and a boy from another planet with mysterious abilities, she wonders just how much stranger the world can get.
