Dullahan-Chan Wa Kubittake

I'm Dullahan Itoshino. A normal girl who can take her head off. From today on 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, story about puberty and love, start!
