Alien Hero of Paris (Male Reader X Marinette/Ladybug)

Preventing a Cosmic Destruction/Battle of Titans

3rd Person POV
Scene: Caline's classroom
"We see Y/N and the others as they were in Caline's classroom as they're chatting with each other as they just finished a test that Caline made for them."
Kim: I still can't believe that Y/N keeps on getting the highest marks on the tests that we do.
Max: *to Y/N* Yeah, how are you able to do that Y/N?
Alix: I'm curious about it, too.
Y/N: I just know how to balance my hero life and my personal life. Since I've been doing that for a long time, I'm used to doing it.
Juleka: *nods* I get where your coming from.
Nino: Yeah, but it's still amazing that you can still do anything that you like while also managing to live a double life.
Alya: *nods while smiling* It really is. *turns to Gwen and Kevin* Did you 2 have a hard time living with a double life as well?
Gwen: *nods* Yeah, it was very difficult at first.
Kevin: But, Y/N helped us get used to it. He kept on helping us until we were used to it.
Adrien: Y/N's a really amazing friend to have. And I'm proud to be one of them.
Alya and Nino: Me as well.
Kevin and Gwen: We are too.
"Marinette was just looking at her fiance full of love as she then went to kiss his cheek and hug him as he hugs her back. They then kept on talking with each other until they heard a beeping sound and they all looked towards the young Ultimatrix wielder as he raises his Ultimatrix by his face and he answers it. It was revealed that the one who was calling him was Azmuth with his assistant, Albedo."
Y/N: Azmuth? Albedo? It's good to see you guys, but why did you suddenly called me?
Azmuth: *through the Ultimatrix* Y/N remember the cosmic storm that was nearing your galaxy that I told you 2 months ago?
Y/N: Yeah, I remember. *realizes* You don't meant that?
Azmuth: through the Ultimatrix nods* Yes it's very close to your galaxy and in a few hours the To'kustar is going to be attacking your planet.
Albedo: It also destroyed a few planets before going to your galaxy.
"All of the people who heard this were now scared because of what Azmuth said."
Y/N: *serious* We'll deal with it. Y/N out. *both Azmuth and Albedo nod as they bid their goodbyes to Y/N*
But Y/N and the other heroes only had a very serious expression on their faces. Y/N faces his other classmates and says."
Y/N: Guys get to your homes and be with your family. We'll handle the To'kustar. *they all nodded and went to their homes*
"Y/N and the others then ran out of the school and went to Marinette's room. Y/N and the others then thought of a plan on how to deal with the To'kustar."
Y/N: I'll deal with the To'kustar. You guys prevent any people to become casualties.
Other Heroes: You got it.
Y/N: *to Marinette* Meet us at the Agreste Mansion.
Marinette: *nods and turns to the others* I'll just go get your Miraculouses from the guardian. *the Miraculous Heroes all nodded* Tikki, spots on! Ha! *transforms to Ladybug*

"She then went out of her room and went to Master Fu's place to get the others Miraculous."
Y/N: Let's go to the Agreste Mansion and warn the others there.
Adrien: *nods* Let's go. Plagg, claws out! *transforms to Cat Noir*

Y/N: *activates his Ultimatrix as Big Chill's hologram appears* It's Hero Time! *slams down on his Ultimatrix and transforms into Big Chill*

Big Chill: Big Chill! *spreads his wings* Alright everyone get on my back and we'll go to the Agreste Mansion.
"Alya, Nino and Chloe then went on his back as Cat Noir opens the door to Marinette's balcony as Emma transforms into Lucky Girl. Gwen then made a mana pathway for her and Kevin as they all then went to the Agreste Mansion."
