A/n: Story covered has changed from it's original, due to me entering the final arc of this story!
When a young man makes a joke wish about taking Issei's place as the Red Dragon Emperor, he gets the wish granted! At the cost of his manhood, that is.
We now see Y/n back in the endless space, with her sitting at a tea table with Brutia.
Y/n: Hello again, Brutia.
Brutia: You seem more well composed than before.
Y/n: Yeah, well, this is what I believe is our third time talking with each other?
Brutia: It is!
Y/n: Normally when you call me, there's something you need to tell me. What is it?
Brutia: Straight to the point, huh?
Brutia then sips some of her tea, and then puts it down.
Brutia: Alright, then. Other than use of your Sacred Gear or the Artificial One I gave you, I don't want you to use any magic at any point, unless deemed absolutely necessary!
Y/n: Okay, what the hell are you getting at?
Brutia: I looked into the history of the family line your current life has! The magic power that's held inside your new body is incredibly dangerous if not trained properly!
Y/n: What the hell are you saying?! What magic power?!
Brutia: I'm afraid I can't tell you that.
Y/n: And why not?!
Brutia: Because in time, they will tell you.
Y/n: Whose they?!
Brutia: Trust me! Everything will make sense later!
Brutia then pushes Y/n away, and she quickly notices that Brutia's visibly worried for Y/n's safety.
Y/n: I'll trust you! But if this shit goes south, I'M BLAMING YOU!!!!!!!!!!!!
Y/n then immediately wake up in my bed, and notice that she's in her bed.

Y/n: *sigh*
Y/n then slowly walks to the bathroom, and as she brushes her teeth, starts thinking to herself.
Y/n: What power is she talking about? Could it be... That weird purple mist my hands let out during the training arc?
*Time-skip*
We now see Y/n in her school uniform with Raynare (Whose still acting as Yuuma), Asia, and Rias having breakfast.
Gorou: Incredible! Rias, I know you're foreign, but this tastes like the real deal!
Rias: Well, Yuuma did help me out with it, and I've been living here for a while.
Y/n: You both did amazing!
Rias and Raynare then blush a bit, which Miki notices and makes a playful joke.
Miki: Looks like our little girl might have two girlfriends!
