Power. That was what Aizen Sousuke wanted. The one word which was enough to make people swarm to it like delicate butterflies to a tempting burning flame. Aizen Sousuke. The one name that brought both fear and anger to many that walked the endless boundary of the human and spirit world. Spiritual Pressure. The one thing that Takamura Sana possessed dangerously more than anyone else. And the one thing.....that was sure to drag her into the Sweet Darkness of the man named Aizen Sousuke.
