Prologue

Of everything Issei Hyodou had to regret in his short life as a pervert, his first girlfriend was by far, the one he regretted the most.

Why so?

Because now he laid on the bricks of one of Kuoh's most popular plazas, with a spear seemingly made of light embedded right in the very middle of his chest.

"I'm sorry." His girlfriend, Yuuma Amano, if that was her real name, said with not even a bit of regret in her voice. "If you want to blame someone, blame the God that put a Sacred Gear in you."

At least the yandere was beautiful. She was sexier than when he met her, with her body growing more curves as soon as the black-feathered wings appeared from her back, and still kept the violet eyes and long black hair of the 'first' Yuuma. Her tight black clothes left little to imagination and Issei would normally like it, if he wasn't dying, of course.

'Shut up.' He angrily thought, too weakened by blood loss to even insult the woman that manipulated him, the woman that made him fall for her, only to kill him on the very same day. 'Shut up, bitch. Let me die already.'

The woman standing beside him couldn't even kill him properly. Her spear missed the heart, and now Issei would have a slow, torturing death laying on a pool of his own blood.

"You were so sweet." Said her with a giggle, sprouting her wings as she was ready to take off. "I wish we could have met in different circumstances."

With that last statement, the Black-winged Angel took flight towards the setting sun, her figure getting further and further until it was merely a silhouette contrasting to the red light of setting sun.

'Man, I never thought I would die a virgin.' The boy thought between his last breaths, the image of a beautiful red-haired maiden forming on his mind, her greenish blue eyes appearing to stare deep into the teenager's own. 'Rias Gremory, I wish I could at least die in her arms.'

As his vision blurred, darkness rapidly taking over, he was able to distinguish a short, shady silhouette kneeling beside his dying body.

The last thing he heard was the voice of an old man saying.

"Hurry, minions, hurry! We have a potential candidate and he's dying. Blues, come and heal him!"

'Why is this happening to me?' Were his last thoughts before consciousness finally slipped over and he died.
