A soul from our world suddenly finds himself in Issei's body. Having a helpful system and one of the strongest sacred gears in the universe he chooses to aim for the top, of course, he doesn't plan on doing it alone...

"That was so worth it!" I exclaimed as everything about me changed. My vision was beyond phenomenal. Not only could I see almost everything from miles away, but from up close, I could see and notice everything. My body felt light, and my thinking process was not only faster but more efficient.
However, the main thing was my heart. To be more specific, hearts. I can feel them. I have two of them. My magic core was on my right chest which is considered a heart, and my human heart. My nervous system evolved, as did my mana circuits. My body was filled with power.
"Let me see the changes," I mumbled excitedly as the system appeared in front of my eyes.

[Congratulations user you have developed a Magic core!]
[With this magic core it will be easier for you to gain mana, It will act as a factory that creates Magical Energy. It functions as an enormous Magical Energy core with tremendous capacity that generates energy independent from her body through breathing like a Dragon.]
[You also have the eyes and brain of a dragon making your comprehension and visual skills on a rank of its own, you can see not only physically but spiritually as well.]

I'm going to be so fucking overpowered in the future. Going through my system I put the points I was rewarded into strength and agility equally. Stretching my limbs I let out a yawn.
<You are fucking crazy you know that?> I heard a deep voice from inside my head talk to me, a smile appeared on my face, it was nice not being alone anymore.
<Maybe a little.> I replied as I was about to walk away, however, I forgot to do one last thing. <Common do it I know you're dying to> Ddraig jocked, I could hear his smile.
Closing my eyes I imagined the way I wanted the boosted gear to look, I liked the idea of making it look like a gauntlet, but I'd rather it be 2 instead of one. Finally, finishing my design I manifested it. both my arms lit up with a red light, bulky gauntlets shaped themselves around them, and finally, the light shattered revealing the gauntlets.

<hooo, this is one of the nicest designs yet.> Ddraig complimented in my head, feeling proud of myself I threw a couple of punches and they felt so natural and comfortable it was as if I was even wearing them.
Taking them off, I headed home with a new friend and new powers.

"Oh my gosh, who is that?"
"You won't believe who it is!"
"It's Issei fucking Hyoudou, one of the perverts!"
