Two years since her disappearance, he encounters a strange girl with the exact appearance. But before he can ask for more information, Renji has already found himself transported to another world.

His only saving grace is that the curse also bears an incredible power. With this newfound strength, can Renji finally reunite with his family before he’s changed beyond recognition?
