Dullahan-chan wa Kubittake

I'm Dullahan Itoshino, a normal girl who can take her head off. From today onward I'll be a middle schooler! I hope I'll get closer to my destined one; but sometimes my heart suddenly beats faster, I want to run away, and my body and mind feel torn apart... is this the thing called "puberty," I wonder?
Heart (head) and body apart, a story about puberty and love begins!
