夢幻優姫～目の前で、敗北し略奪され堕ちる少女～

The protagonist, Yuuichi, found a strange girl in a rainy alleyway. A beautiful girl, dressed in pink and frills. A girl who reached out and grabbed his hand, ever so gently. She held onto him, her hands shockingly cold.

Then, she told him--
"I finally found you...the source of my power..."

At that moment, the world around them crumbled, and they began to fall down. When they stopped, they were in a city Yuuichi had never seen before.
