[Three years ago]
A young man can be seen being thrown onto a locker by a larger student..

Student: And stay down you freak!

The student sneered at the downed boy before he walked away. The young man was watching the bully walk away for a few seconds before slowly getting back up.

???: Every fucking day, he does this..

This boy's name is Y/n Santos. A mid height 12 year old boy who was having the worst luck any kid can have been in school: Bullying.

*Your 12 year old self change the color of your eyes to Dark Yellow*

He picked up whatever work that wasn't taken by them and headed to the principals office to get some help with the bullying.

[At the Principals office]

Principal: Y/n, I know it's rough, but I'm sure that it'll be fine the next day.

This is what the man always used whenever Y/n begged for helped. It didn't matter even if he showed up with bruises on his body, Principal Gary would keep on spewing out excuses.

Y/n: You said that last time, but it keeps going.

Principal: I'm sorry Mr. Santos, but I cannot help you. Now, you should get to class.

Y/n can only sigh as he walked out of the principals office, much to his disappointment as once again. He could've heard behind the closed door of the principal speaking ill about him.

Principal: Annoying little shit...

Y/n somehow heard this and growled silently. Once again, the man refused to help him.

The young man then entered his classroom, just as the teacher stopped his "lesson" by glancing at him.

Teacher: Late again, Mr Santos.

Y/n: *tries to defend himself* But, Mr.-

Teacher: *cuts him off* Don't need to hear it. Get to your seat.

Y/n grumbled as the student started at him with sneers and snickering directed towards him as he sat on his desk at the corner of the wall as the teacher started his lesson.

[Somewhere far]
A hooded figure can be seen lurking in the shadows with an Item in hand.

???: This Special will prove useful for young Y/n.

The figure then placed it down at the Santos doorstep. He then waved his hand as particles of light emerged from the bottom of his hodded disguise and rose up, getting rid of the cover-up.

???: A very deep shame Lord Beerus's Son had to undergo so much pain. But this..will change his life for the better. Hopefully, Plagg will not give him too much trouble. Now for the next step of my plan.

The unknown figure then floated up in the air as he showers into the skies.

[Timeskip]
Y/n was walking back to his home with some bruises on his body from being beat up after deciding to cut school. Because of the bullying and mistreatment, the young men ultimately decided not to attend that hellhole of a school anymore.

He got out walking to his adoptive home that he currently lived in since he was a baby.

Y/n never knew who his parents we're. What he knew was that when he was at least one year old, he was left at at a random doorstep with a newlywed couple. The husband and wife felt sad that the child was abandoned and decided to raise him as their own.

[Back at his kindergarten years]

*Your 5 year old self. Replace the color of your eyes with dark yellow*

When he first came to the kindergarten, he was instantly swarmed by the other students about his cat tail and Cat ears as they were mesmerized by his extra appendages. Some of the girls petted his head, which caused the young boy to purr a few times.

Those were his best years. But when he was in 8th grade..that's when he was ridiculed as a freak. Y/n was tormented for not being a normal human because of his ears and even had some of the people he thought to be friends from preschool bullying him too.

He was beaten, had his work taken, his lunch and lunch money stolen and so on. It got to the point where he tried going to the principal to get the bullying to stop..but the old bastard turned a blind eye at it. After this, Y/n hated his school life and began to stop going to the school, since all that place did, have him nothing but torment.

Y/n makes it to the door, but spots a hexagon shaped box with Chinese markings on it.

Y/n: Strange..

Y/n picked up the item before unlocking the door and entering the house. He winced in slight pain as he looked at the reflection of the injuries he got.

Y/n: I-i'm home.

A woman peeked her head back from the kitchen.

Amelia: *looks towards the door* Y/n. What are-

The woman get a good look at Y/n as as she sees the bruises on his body. The mother instantly rushed towards her son.

Amelia: Oh my God..*turns her head to the stairs* Richard!

Heavy footsteps came charging down as an older Kris with light gray hair came in view.

Richard went towards his son and looks over the injuriescovering Y/n's body.

Richard: *worried* What happened to you?!

Y/n: The same thing as before: Getting beat up by the other students with the teachers barely helping me. I'm tired of this.

Amelia: What about the nurses? Didn't they help you?

Y/n: They barely did anything. Just some rubbing alcohol* but that's that.

Richard: Do you want to stay at that school?

Y/n didn't speak, but he did shake his head sideways, getting the parents to understand that he does not want to.

Richard: Okay. Starting today, you will no longer go to that school.

As the Santos family was thinking on what to do next, a knock on the door cut them out of their thoughts.

Richard: Who is there?

???: I'm the truant officer from the school.

Y/n: Not this guy again...

Richard: *quietly to Y/n* Kid, why don't you go upstairs to your room?

Y/n: Sure.

As Y/n made his way upstairs, the Father then went to the door and opening it to reveal the said officer in front of him.

Truant Officer: Hello.

Richard: Can we help you?

Truant Officer: Yes. I'm here to take your son back to the school.

Amelia: And why do you think we'll let that happen?

Truant Officer: Because he has been cutting class. And it would not look well on his record.

Richard:We don't need some rent-a-cop telling us on what his academic record

Truant Officer: So you want me to report to the principal that your son is no longer going to attend the school?

Richard: Yes.

Truant Officer: But your son would have to come back tomorrow to tell him.

Amelia: And we will go with him.

Truant Officer: Very well. Have a good day.

Amelia watched the Officer walk off as she closed the door in front of her as she turned to her husband.

Amelia: That school is relentless. It's not safe for our boy.

Richard: Yes. No way we can go to the police here. Those pigs can easily be bribed and turn a blind eye.

???: Perhaps I can be of assistance.

The Santos family turned to see someone behind them to see a man with ghostly white hair quaking a business suit.

Richard: W-who the hell are you?!

Unknown Man: I am a family lawyer of the boy you call Y/n.

Amelia: How do you know of our Son's name?

Unknown: From his own relatives. They have spoken to me about Y/n and told me about where he is.

Richard: And what exactly do you want with him?

Unknown Man: To tell him about his inheritance. His main family was very secretive. Which is why I made the decision to meet the little DemiGod

Richard: DemiGod?

Unknown Man: Oh, Heavens. I think this form should entice you both better.

The man started to float in the air as light begins to shine from him in the living room. This also blinded the Santos parents as they were forced to cover their eyes. When the light dimmed, the husband and wife felt that they can see now.

Richard: Ugh..that stinged my eyes..

Amelia: What was that?

???: That was just my human disguise.

Richard and Amelia looked to see someone else besides the person they previously saw. What stood is a tall, thin humanoid with pale blue skin, white hair, violet eyes, and rather effeminate features. He owns a long scepter with a gem that floats above it and is usually seen holding it in his right hand. Around his neck floats a large light blue ring. The man's attire consists of a maroon robe, a black cuirass with white and orange diamond decorations, and a blue sash. He also wears black high-heeled shoes with long toes resembling winklepickers with white spats.

Richard: Okay, what in the hell?

Whis: Nice to officially meet you two. You may call me Whis. Now..I believe they is much to explain about Y/n.

[Y/n's POV]

I was in my room looking at the weird hexagon box that appeared on the doorstep.

Y/n: This is very odd.

Due to my own curiosity, I decided to open the box as it revealed a silver ring.

Y/n: A Ring?

All of a sudden, the ring started glowing as a small sphere of (f/c) light skinned in front of me. When it diminished, a small being materialised out of the light and out came is a small black creature that is 10 centimeters tall.

He has a large head and small body. His appearance is very cat-like, having cat ears, a tail, two cat incisors, and green cat-like eyes, along with one whisker on his forehead and one whisker on each cheek.

Y/n: *blinks in confusion* Okay, what?

The floating Cat being then yawned and stretched his little before meeting his gaze at me.

Cat Kwami: Hello there. And damn..*looks all over him* You look like you been through tough shit.

(Yes..Plagg will definitely start swearing sometimes in this book)

Y/n: Try getting my ass kicked on a daily basis. *points to his cat ears and tail* All because of these.

Plagg: No fellow kitty should be hurt and abused. Call me Plagg, my guy. I'm your Kwami.

Y/n: My Kwami? And what can you do?

Plagg: I'm not one to give out long explanations of what your powers are. Basically, you have the power of Destruction.

Y/n: So like anything I touch will disintegrate into nothing?

Plagg: That's correct. But I wanna know something. Where did you get those injuries from?

Y/n: Some School bullies of mine. They recently did this to me when I was going home.

Plagg: Well, that's not gonna sit right with me. In fact, I will go to those two and deal with them myself.

Y/n: Wait..why are you doing this for me? we just met.. and do you even know them?

Plagg: Actually..a certain blue tall guy told me about you for the longest time. And I thought it would best if I can relieve my wielder of troublesome mishaps. Be right back.

Before I can even say anything to him, Plagg flew through the wall, heading outside.

Y/n: I wonder what Plagg is gonna do. I better see if they got that Officer to go away.

I got off the bed i was on and headed downstairs to my folks.

[With Whis and the Parents]
Whis was explaining how his real birth Parents were two gods not connected to this universe managed to deal for one another and have Y/n. However due to strict multiverse rules of sort and to make sure their child would not suffer by their superiors.. they had to give him up.

Amelia: So..Y/n was never abandoned? His parents had to give him up?

Whis: It was a bit strict for a God of Destruction to have offspring with a being not connected to our universe. That why they did what they did.

Y/n: Mom, dad,  is that truant Officer gone.

The sound of Y/n coming down the stairs got their attention as the young boy got into the living room. Y/n then spots Whis with his patent as he raised a question.

Y/n: Umm..May I ask who you are?

Whis: I am your father's angel attendant, Whis. Nice to finally meet you.

Y/n: Angel attendant? I don't recall my dad ever having an attendant

Whis: Oh, you must be mistaken. I mean your Biological Father, Beerus: the God of Destruction.

This brought the family in shock of what Whis had just explained. The fact that Y/n's real Father was a God. And because of that, this makes him a demi-god.

Y/n: *perplexed* M-my real father is a God?!?

Whis: *sees Y/n's injuries* I almost forgot. Let me heal you up, dear boy.

Whis raised his staff as the injuries that Y/n had on his body started to disappear. The young man felt healed like never before.

Whis: There. That should be better.

Y/n: So, what happens now?

Whis: Well, since you now know your Godhood, it's only fitting for you to come with me.

Amelia: So..are you taking my Son away?

Whis: It's not gonna be forever. Just about three months.

Richard: Three months, huh?

Whis: This will Also give Y/n the chance to grow stronger. Plus with that Miraculous I gave him should really help him out.

Richard: Miraculous?

Whis: I think it's best we wait until Plagg returns. He has a..personal duty to attend to.

[With Plagg]
The small Cat Kwami can be seen flying towards the bullies that harmed Y/n.

Plagg: Hey, you two.

The bullies turned to see a floating cat-like creature in their faces.

Plagg: I heard that you like to torment a boy named Y/n, right?

Bully#1: So what if we did? Little shitstain get what he deserves.

Bully#2: Yeah

*just note that Plagg received training(although reluctantly) from Beerus to control his Cataclysm, even without an owner, so he would not cause too much damage*

Plagg: Is that so, huh..well guess what motherfucker.

Bully#1: Huh?

Plagg: Cataclysm!

His little paw began to radiate with dark energy as he flies towards the bully in front of him and scratched him.

Bully#1: *jumps back* Ow! You little motherfu-

Bully#1 then began to felt himself becoming weaker as his entire body and clothing began to deteriorate. He looked down to his hand as it quickly turned numb and pale. Even his clothes were crumbling to dust as his whole body(skeleton, muscles and etc.) were reduced to a black sludge that fell on the ground.

The second bully stated in horror seeing his friend melt in nothing but black slime before it turned to dust.

Bully#2: Y-you little bastard!

Plagg then turned to the second student, with a murderous glare, which frightened him to the core. He then tried to back away and run, but got cut off when Plagg flew in his face.

Plagg: Your face is ugly. Mind if I rearrange it?

Before he can protest, Plagg whipped up another Cataclysm, raise it close to his mouth and blew the Cataclysmic energy directly n the boys face.

(This what he did is like literally splashing a bucket of hydrochloric Acid in your face, just to let you know)

This had an effect on the bully as the second bully's face began to melt off, with his skin, muscles and eyeballs falling off like tar. This was giving him agonizing pain until his head was reduced to nothing but a slimy fleshy skull before dropping to the ground dead.

Plagg: Hmph..serves them right. Now to head back to Y/n and the others.

With that, Plagg flew back to the Santos household, leaving the melted corpses of the former bullies of Y/n.

[In Paris]
A small gasp can be heard from someone's voice. The scenes shows a small red being inside a parallel world filled with objects from around the world.

It resembles a ladybug, with dark blue eyes, has two antennae, a large black spot on her forehead, back, and each side of her head, and a short tail with three tips aligned vertically...

Her name is Tikki: The Kwami of Creation.

Right now, she then felt the presence of the other half of the two strongest Miraculous emerge at last.

Tikki: Plagg..you finally come out.
