Alien Hero of Kuoh (Male Ultimatrix Wielder Reader X Highschool DxD Harem)

Rating Game/The Harem Begins

3rd Person POV
Scene: ORC clubhouse
"We see everyone in the ORC as they were getting ready for the Rating Game against Riser as everyone but Y/N and Asia was wearing their school uniform Asia was wearing her Nun outfit and Y/N was wearing his signature Jacket. Everyone was doing different things to counter their nervousness, Kiba sharpening his swords, Koneko putting on hand guards on the both of her hands, Akeno, Issei, and Asia drinking tea so that they would feel less nervous, Rias going through some strategies in case plan a doesn't work, and Y/N was looking through his forms to find a way to counter, Riser. Then Sona and Tsubaki came in the room to see how they are doing."
Sona: So Rias how are all of you?
Rias: Well most of us are nervous, while one of us isn't.
Tsubaki: *confused* One of us?
Akeno: *points at Y/N* Look over there.
"They then looked towards the young Ultimatrix wielder as they was that he was experimenting with changing his arms into different forms to find a good way to beat Riser. Sona and Rias were looking at Y/N as they were smiling at how much he'll do just to protect them as they fell in love with him more. Y/N then stops experimenting with his forms as he then started to some martial arts training to get his heart pumping. Sona and the other girls all saw that he was training again, and they couldn't help but blush when they saw his muscles when he was training. Then Belfast entered the room and was about to say something to Rias, when her eyes landed on Y/N as she couldn't help but blush beet red, when she saw his muscles. She then tried to shake off her blush, but she was still blushing lightly."
Belfast: *blushing lightly* L-Lady Rias, it's almost time to start the Rating Game.
Rias: Alright then we're off. We'll see you after this Sona.
Sona: You will also Rias, kick his ass.
Rias: You know we will.
Sona: Be safe everyone. Especially you, Honey.
Y/N: You know we will. Of course I can't let my fiance be sad now, do I? *Sona blushes from hearing that*
Sona: *blushing* Y-yeah. *smiles, but still blushing*
"When Belfast heard this she couldn't help but get jealous, but she quickly hid it."
Belfast: Before, I forget. Lord Lucifer will also be watching the Rating Game.
Rias: What are you planning, Nii-sama?
Y/N: *puts a reassuring hand on her shoulder* Don't worry, whatever it is that he wants, it won't stop us from winning the Rating Game.
Rias: *smiles at Y/N cheering her up* Yeah, your right. We can handle it.
Sona: Me and Tsubaki will be watching from the VIP Booth, with my parents, Sirzechs Lucifer, the other Devil Kings, and with both the Gremory and Phenex family will be watching you guys.
Y/N: So, I get to humiliate Riser, in front of his family and the whole underworld? *smiles menacingly* This is going to be fu~un.

(The smile that your doing)

"The others were shaking in fear of seeing Y/N like this as they all had one thought."
Everyone else: 'Note to self: Never piss off, Y/N, if I ever want to live.'
"Rias then snaps out of her trance as she then asks everyone if they were ready."
Rias: All right, everyone ready? *they all nodded*
"Then Sona, Tsubasa, and Belfast left the room as they then entered the magic circle that teleported them into the alternate space. Everyone looked around while Asia and Issei were confused and it looked like they were still in the clubroom and Issei asks Rias a question."
Issei: Did I messed up the magic circle again?
Y/N: No you didn't bro look outside.
"Then he and Asia both looked outside and they were shocked to see that they were still in the school but the sky was different."
Issei: Whoa, now that's cool.
Rias: Alright everyone so were here in the clubhouse so Riser's base is going to be somewhere here in this area. *points at a part of the map*
Y/N: Riser's base is going to be in the Principal's office. And from what I see he's going to capture the gym so that he can take midpoint early.
Akeno: That was a good observation Y/N.
Y/N: I just put myself in the mindset of our enemy and just from his cocky nature you can easily see that he gave us home field advantage even though were outnumbered but we out powered them. So everyone remember your training also remember that they may use Phenex tears. If they do, call me and I'll send my Echo-Echo clones to help you guys. He may have us outnumbered, but we can overpower him. So here's the strategy that were going to use. *tells them about the strategies*
