11 Side Arc 1 Finale: Best wished I-ISLAND I'll Come Back During Canon.

[Next day-2 days before leaving I-ISLAND]

[Kaito POV]

After the incident night I woke up at 11:00AM, thanks to the concentration breathing (previously called demon slayer breathing) I realized that it helped in the process of healing external wounds and minor internal ones like minor muscular rupture and stuff (MINOR just to be clear).

Mom left a note telling me to wait for her in the room and relax, that we'll go later to some theme park to enjoy ourselves and make up for the time she has been busy.

Since I was feeling kind of guilty for what I did yesterday I decided to obey and relax at the room and focus my breathing to focus in healing.

After some healing, mom came back and spoke to me about what she has been doing, she told me that it was a surprise for me once I was accepted at UA and the she will allow me to practice martial arts.

At first I was confused about the change in her behavior so, when se went to take a bath I took her phone and saw her messages, and boy was I for a treat.

To begin with she has been texting and I'll assume meeting with a guy named Kobayashi Kenny, whom I believe it's a relative of mine, she also had some texts talking about some "project DIMENTIO" but, all the texts were too ambiguous so in the end it was a dead end.

Taking into account this information I believe that whatever this "DIMENTIO" thingy is it has to be related to this surprise I may receive 10 years from now (hopefully).

I know it sounds stupid coming from the guy who saved kids and a very suicidal way but, for now I'll let mom to handle her situations I trust her enough to do it.

After a while mom and I left to the theme park, there were allot of attractions, from the Ferris wheel to the carousel all was awesome, mom and I spend the whole day doing stuff together.

After that we went to a picture booth to commemorate these moments, sometimes you think you have your whole life to spend with your loved ones, but just as Kai experienced life can have unexpected twists. So one should always treasure moments like this, true I want to become a hero and most likely have to spend my time training or studying but till then I'm happy being a momma's boy (PS: Happy mother's day).

Now it's the last day of our stay in I-ISLAND, not gonna lie, I'll miss this place so the last day we decided to visit the Hatsume's, yes I did told mom about them and yes I got an earful but she let me off the hook for leaving me alone (I'm scared to think what would happen if I tell her about my little "hero" stunt *shivers*).

When we entered the Hatsume's did their routine of eccentric antics and showing us their "babies". I am down to clown with gadgets but I feel like it takes the essence of being a Demon Slayer but, for now I'll ignore the feeling and say that these are tactics.

My blueprints were successful from my "ignite gloves" to my "pile destroyer" all were good ideas and successfully executed as gadgets, the Hatsume's asked me to give them the rights to sell these gadgets if given a chance and I agreed as long as I get a discount for each gadget that I buy, I chose the discount because I thought it would be better than money, dunno maybe I have stingy genes.

Mom and I left the store with a smile and went to the hotel room, while I was about to sleep mom entered my room and whispered in my ear "I know what you did, I'm your mother after seeing those bruises of yours, the scar and saw the news about the incident that happened at the playground I connected the pieces" she said calmly.

I was about to ask for forgiveness but before I could move she said "I'm proud of you son, but you need to think of yourselve as well. (now dripping tears) If something had happened to you I don't know what I would've done, so promise me you will never do something like that until you become an official hero" mom said about to cry, even I had tears forming in my eyes.

"I promise, mother" I said without thinking it twice.

She then kissed my cheek and left the room. I felt like an asshole for what I made my mother go through, I'm a kid for fuck's sake, how would I feel in a situation like that as a parent?

After crying a little I realized that this incident made my resolve stronger, to become stronger not only to protect others, but to also protect myself so that mom doesn't have to worry about me.

[Final day in I-ISLAND]

It is time to go and I feel sad, but at the same time excited, since mom allowed me to train martial arts, those will become a great step for my future but for now I'll enjoy what I have, life is meant to be enjoyed if I focus too much about training and getting stronger I would be avoiding the things I have at plain sight.

After bidding our farewells to the Hatsume's we left I-ISLAND.

Once we came back everything went back at normal. I would train the concentration breathing, Midoriya would ask me to play and I would comply, I learned new things about forge and saw many dos and don'ts when forging, went to Hermes's shop and bought with savings of my allowance some Scarlet Crimson Iron Sand and Scarlet Ore for he's katanas.

I told Mashiro-ossan to choose the sword he liked the most for the 1st one of my arsenal and he decided to make a normal katana since he was not familiarized with the Scarlet Crimson Iron Sand and Scarlet Ore so he had to get used to them.

Thankfully since those were my materials he was wasting he would give me 2 of my works free of charge to which I happily agreed, honestly I was surprised about him not hearing about the ores, now knowing the ores where somewhat confidential information I am wary about Hermes may do to me in the future but, you know cross the bridge when you get there right?

I went to bed early and said out-loud "things are just as complicated as I imagined, with I-ISLAND I can say for sure that this world's story is being re-written. *sigh* What else should I learn, martial arts are great and all but I still lack on speed and defense, maybe the black leg style from Sanji? I have memorized it so it's not too wicked I mean I have Zoro's sword techniques so this is not that far…right?

(Note: Kaito will only use 2 sword style at best case, why? Because I believe it is weird to fight with a sword in your mouth, sure Zoro does it and it's cool but Kaito it's not Zoro so yeah bye bye).

I was getting sleepy and closed my eyes waiting to see what other things will this world dive me.

[5 Years later]

I woke up with my body all messed up from staying playing games too late at night.

I look at myself in the mirror and my slim but well-toned body covered with scars in my arms, legs and body (Basically everywhere but the crotch, waist, from the neck up, butt, feet and hands).

(Note: small scars and in diverse places not literally covered in scars).

"Welp first day of lower secondary school, I'll ask Midoriya if he has a copy of All Might card #77 for my collection" said Kaito leaving he's room.
