Dangerous Love

Ayano Aishi is a yandere girl, a girl that doesn't feel emotions.
She doesn't feel emotions, until she meets the love of her life.
And the love of her life is named Taro Yamada, a handsome young man surrounded by rivals.
After killing her first, most obvious rival, Osana Najimi, a childhood friend of Taro's, Ayano came to the conclusion that she simply couldn't kill again.
The shaky feeling after her blood fell to the floor, the hallucinations of dragging Osana's body along the ground, blood still pouring from the stab wounds on her throat.
How could her, Ayano Aishi, the yandere girl of Akademi High School, be unable to kill?

Ayano doesn't understand why she can't kill without crazy hallucinations and pangs of nausea, but there's one thing she knows for sure: she's going to have to find a way to eliminate her next rival, Kokona Haruka, in a peaceful way.

Note: The rival shall be Kokona Haruka instead of Kizana Sunobu because I find Kokona's personality easier to work with.
