An Eternal Child (Highschool DxD/DOOM male reader insert)

Raw Power

*Issei POV*

"I'll win, for you Rias."

I summoned my gauntlet and felt the power run through me. Thanks to my training I no longer need to wait to power up when I first summon my gauntlet, which meant that this guy was going down.

"I hear you've been going around and disrupting the peace of local churches. Now while it isn't our direct problem, since you're causing a disturbance we'll have to stop you...permanently." I told this "Slayer".

He didn't say anything, he just stared at me and watched as I paced around waiting for him to make the first move...yet he didn't.

"You scared or something?" I asked him as I took up my fighting stance.

"Issei, make it quick. I can feel his power rising by the second but you are still more powerful for the moment." Rias told me.

I nodded my head and readied myself.

"Now's my chance to show how well my training paid off."

I planted my foot on the ground behind me and pushed myself forward and aimed my fist right at this chumps face, I couldn't help but let a grin spread across my face as I knew I'd wipe the floor with him.

BAM!

I was now standing in place and I felt something against my fist...like he was holding my fist back. I slowly opened my eyes and what I saw nearly made me cry.

"He...stopped my...punch?" I asked aloud.

He took the blast but he caught my fist and all that happened was that his shirt was in patches and I had torn a slight hole in the side of his jeans.

"You talk too much."

*Rias POV*

I watched as all the Slayer did was slowly pull his fist back and propelled it into Issei's chest and sent him flying back to my feet. I quickly crouched down and made sure he was okay, I felt along his chest as he struggled to take in a deep breath.

"Rias what's wrong with him?" Asia asked as she crouched down next to me ready to heal Issei.

"At least three, maybe four of his ribs are completely broken." I told her as the green glow began to emanate from her hands.

"The rest of you form up and attack. Do not let him get a breath for even a second." I commanded.

I watched as they all leapt forward and attacked the Slayer at once, they would do me proud, I just hoped that their teamwork would be enough.

"Be strong my family."

*Your POV*

I watched as these children lunged towards me with no skill or thought behind their action.

"How pitiful."

 The first to try to strike me was the short white haired girl, her kick was a good choice but she gave too much time for me to strike first so I grabbed her leg but as I did so I saw a blonde flash in the corner of my eye.

"So it seems the blonde boy is her knight."

I flung my free hand around and grabbed the boy by the neck and threw both of them towards the black haired girl standing behind the others. I looked behind me as I felt the air around me move and stepped aside as the blue haired girl swung her sword into the ground.

"How do you move so fast?!" She questioned.

"You're predictable." I told her.

"Impossible!"
