KAEDE ～淫辱に堕ちる魔法少女～

Sakaki Seiji signed a contract with a demon.
The thing standing between him and ultimate power is a young girl also contracted... to stop him!
Her name was Kaede Tendo. She had more than enough fighting spirit. But Seiji bypassed her surface level defenses.

Can Kaede deny the pleasure that's corroding her soul?
