The first volume of the Tasogare Otome × Amnesia manga series covers the pilot manga "Maiden's Heart and Evening's Sky" and Teiichi Niiya's first batch of cases with Yuuko in the Paranormal Investigation Club.
Just like in one of the ghost stories in Seikyou Academy, a ghost named Yuuko appears from behind a boy named Teiichi. The girl usually stays at the school's shadow, a victim of an enigmatic demise.
In order to know the truth, Yuuko and Teiichi form the Paranormal Investigation Club.
