Kizumonogatari: I Tekketsu-hen

Follows Araragi's encounter with the vampire Kiss-shot Acerola-orion Heart-under-blade and his journey back into humanity from being a vampire."I think it's about time I talked about Kiss-Shot-Acerola-Orion Heart-Under-Blade. I believe it's something I have to do. I met her in the spring break between my second and third years of high school. That meeting had such impact and was also quite devastating." (Aniplex)
