"Maybe I wish I could die, maybe I am dead!" Momsen, Taylor/The Pretty Reckless - Going to Hell
Kara no Kyoukai: Shuumatsu Rokuon/The Garden of Oblivion is a side story that takes place after Mirai Fukuin and it is just as awesome as the main story and the afore mentioned side story.
This new mystery/thriller/horror story has a really immersive storytelling, just like everything in this franchises (Nasuverse) and Shiki stills just as badass as she used to be and the story is focused more on the female characters this time.
Kara no Kyoukai is a masterpiece of the Japanese litereature, and this SS is a great addition
to the franchise. Read it you won't regret it.
