Master Mosquiton

In the 1920s, Inaho uses her blood to bring a vampire named Mosquiton back to life, making him her servant. She seeks the O-Part, an object that could grant her immortality. As they pursue it, they face opposition from various supernatural beings. Later, Inaho, a Catholic schoolgirl, finds that Mosquiton is feeding on her classmates and kills him, only for him to be resurrected when her blood touches his remains. He then becomes her slave and takes a job as a history teacher. Inaho teams up with Mosquiton, along with Yuuki and Honou, going through various adventures. A key objective for Inaho is to locate the legendary O-Part for financial gain.
