Haraiya Reijou Nicola No Komarigoto

Nicola von Weber is no ordinary schoolgirl. Endowed with memories of a past life as a Shinto exorcist and natural psychic abilities, she uses her exorcism skills to protect others from malevolent apparitions. Her regular client is Sieghart von Edelstein, a childhood friend and a ravishingly beautiful marquess. Ever since Nicola saved him as a small boy, he's been smitten with her, but she is less enthusiastic about him. In this first installment, Nicola clashes with ghosts, doppelgangers, and more than one ill-fated romance. Most spooky apparitions seem to spawn around the school, where the students' propensity for gossip provides ample sustenance for their existence. Here, the more vividly one imagines something, the more likely it is to come true. However, as first-year student Nicola ventures beyond her schoolgirl life at The Royal Academy, she finds that the tenacity of spirits (and grudges) means that they can turn up in the strangest of places.
