is a Japanese light novel series written by Masaki Okayu and illustrated by Torishimo. It centers on a teenage boy and a killer angel from the future who constantly gets him into trouble and kills him violently and repeatedly, often removing his head with her spiked club named "Excaliborg", only to resurrect him seconds later. The novels were first serialized in the Dengeki hp magazine published by MediaWorks. Later, a manga version was created, written and illustrated by Mitsuna Ouse serialized in Dengeki Comic Gao!.
