You witness a

Going after the source of the noise, you witnessed a bloody scene.

On the ground lied a boy who was wearing the school uniform. Stood on his body was a girl in a black bikini (or something look like that). She had a pair of black feather wings on her back, and her hand held a light spear which was piercing through the boy's chest.

"Tsk, a useless Twin Critical. Such a waste of my time... "

She raised her head and her eyes met yours. Then she made an evil smile: "Human, you're unlucky. I usually leave no witness."

She rushed towards you with a clear intent: impale you with the light spear in her hand. To her surprise, the spear was dispelled when it touched your skin.

"How... "

The light power belongs to God, it can't harm me. When she was stunned, you quickly rushed to her behind and put her into a coma by a chop: "Sorry, I don't have the habit of explaining my power to enemies."

You turned and walked to the boy. Standing next to him, you realized it's too late to save him now. Suddenly, a red mist came out of his body and floated above his corpse. When you touched it, it solidified to a red gauntlet.

You heard that there's someone coming. You quickly opened a pocket dimension and put the gauntlet in. I always want to do this since I played a game the first time.

The next moment, a red-haired girl arrived. She looked around, then asked you: "What happened here?"

You pointed to the girl lying at your feet: "This girl murdered a boy and tried to shut my mouth by killing me."

"You are not a normal human, aren't you? I'm Rias Gremory, daughter of the Gremory Clan. Who are you?"

"I'm Michael Hazelton."

"No, I want to ask what's your race: devil, angel or... "

"Sorry, I can't tell you that."

She was silent for a moment, then said: "If you're not a Fallen Angel, then hand over that girl. She dared to kill human in my territory, she has to face a punishment."

"No, she is my prisoner now. Don't worry, I promise she will not harm anyone ever again."

Rias stared at you, then turned her back, carrying the boy's corpse and leaving: "You better keep that promise, or you'll have to face me again and it wouldn't be nice to you."

Looking at her back, you murmured: "We'll meet again soon. And I swear it would be nice to me."
