Nanagi Shizuku, eighteen years old.

Born in a secluded village called Amaku Village, she murdered her parents at the age of fourteen. Before their bodies were discovered, she went on to murder ten more people over a six-month period. Upon turning eighteen, she massacred everyone in the village. She then surrendered herself. During her interrogation, she showed no remorse, exhibiting provocative behavior and even murdering the police officers in the interrogation room. Due to her exceptionally rare cruelty and the heinous nature of the crimes, she was immediately sentenced to death, a judgment considered highly appropriate. However, during her transport, she vanished in an accident of unknown cause. As her body was never found, the police concluded she had escaped and issued a warrant for her arrest...

And now, that very girl was living in my home as my girlfriend.
