Chapter 1
-My character-
My name is the same as my real name. I'm the same age. But I'm the 3rd full Saiyan in my lineage. And I was closely related to my great great great grandfather, Son Goku. So I got the exact forms, and power level as him. My mom is Half Saiyan and my dad too so I became a Full Saiyan. But I was considered more dangerous than Son Goku, as he let his guard off during battles, but my guard even 1% is always up. As I knew how dumb my Great great great grandfather was, I focussed on my intelligence too.
-Story-
Just to protect humanity, I joined the demon slayer corps. I had a nichirin on my right hand covering the bottom two fingers and the rest of the palm, I used it just for killing demons. I could fold my hands even while wearing it, and I can take it off anytime. I became a hashira in one and a half months (you know why, though I never revealed my forms), breaking Muichiro's record Of the youngest hashira and the record of becoming the hashira this quick.
When I joined the hashira team, I was greeted by everyone there. I used to talk kindly with everyone there. That's the first time I saw Shinobu and fell in love with her. (Love at first sight). I gave my special introduction to her too. But Sanemi thought that I was a fraud. Since I didn't have any breathing techniques and only used pure strength to kill demon. He didn't know I was a Saiyan (Cuz I hid my identity to all). So that night I took the entire Hashiras to a demon cave. There used to live 100s of demons. We were standing at the middle of that cave, especially me. A swarm of demons appeared. Since Sanemi thought I was a fraud so he took out his Katana just in case if something bad happens cuz he doesn't believe me. But I got all the demons out easily and quickly. When I killed every demon, I came out from that position and everyone saw me covered in blood, my clothes, my hands were the most covered with blood. The Hashiras were just standing, thinking about how strong I really am. Right at that time, a demon came from the right, where Shinobu was standing. No one sensed that demon coming. But I saw and killed it before the Hashiras and the demon can react. I said "You try to lay a finger on my friends, I'll make sure you won't be existing anymore" Shinobu said "Such great speed, even faster than me". I proved them that breathing techniques don't always need to kill demons. We returned to our home. I got my room beside Shinobu's room. I was awake that night and was meditating on the rooftop. Shinobu was also awake and she came near me. I sensed her from afar but acted as if I didn't. She said "Hey". I opened my eyes and saw her sitting beside me. I said "Shinobu San, you're awake this late at night" she said "Yes, awake with you" she smiled at me and so did I. We had a long talk. I got to know Abt her sacrificing plan, she only told this to me because she also had a crush on me and so she trusted me. So I said "Dw, on my watch, no one's gonna lay a finger on you." I smiled. She was happy to hear that I would protect her. Soon after a while, a demon appeared from behind Shinobu, I saw it and killed it instantly. Shinobu kinda recognised that demon to be strong but seeing me killing it instantly made her shocked. She asked "How are you so strong and fast?" I said "I'll tell you everything about this later. For now keep it as a secret between us. I don't want others to know that I'm strong." She said, "if you say so, I'll keep it as a secret for now" I said "Thanks, I'm glad I can trust you". She said "You're welcome". This is how days passed by. Then one day, at midnight, she came and knocked on my door. She wanted to stay in my room for one night. So I quickly let her in (the fact that it was very cold outside too). I asked her Abt her room's condition, and she said "it was captured by the kamaboko squad for parties" I asked Abt their room and she said "They say, their rooms are very messy so I couldn't stay there" so I said "okay, then tonight, you stay with me". I gave her tea, 🍵, I had my heater turned on so it was warm inside. She said she liked the way I stayed organised by myself. I said "Arigato". After we drank tea, we went to sleep, turning off the lights. The next thing shocked me, she said "Hey do you mind turning around towards me, and hugging me while sleeping." I said "H-Hug you?" She said "Yes" and so I did. *Me thinking:- Damn, I never thought I would sleep with someone who I love* She said "You're warm", I had no words, I was silent. She asked "why are you not saying anything?" I said "Cuz I don't know what to say". She put her hands on me, and grabbed me. She asked "how do I feel?" I said "soft". She said, "The Kamaboko Squad may mess up my room. I'll have to spend the entire day cleaning it." I said, " I'll help you with your room cleaning" she said "really?" I said "yes" she said "Thank you very much" I said slowly "I should be thanking you" she asked "what did you say?" I said "nothing". She said "let's sleep then" I said "sure, GN" she said "Gn". As I said I will, so I did. The entire day went normally.
_1 month later_
On Monday everyone decided to defeat muzan on Wednesday. But on Wednesday, I had special work on my parents side, so I reached the infinity castle late. Before teleporting, I sensed that Shinobu's in danger. When I teleported, I saw her half absorbed by Douma. Kanao tried to stop Douma. But she failed. So I did her work, I sliced Douma from between. Shinobu was in a bad condition but she could still be alive till I fought Douma. I said "Kanao San, pls take her away from her, I'll handle the rest" Kanao said "but will you be able to do it alone?" I said "leave it to me, Kanao San, I promised Shinobu San that I'll protect her, so that's what I'll be doing now" Kanao takes her away from that place. I cover them with an invisible forcefield. I said "Kanao San, don't move 5 metres from there and don't let Shinobu San do it too." She said "Okay" "Douma said "Oh so you'll not let me absorb her. How heroic"
I said, "you try to lay a finger on her, I'll make sure that all of your atoms will be out of existence. You have to get over me before you can get them" Douma said "Sure. Let's do it"
_The fight begins_
Douma tried to hit me with everything but I dodged every attack.
Douma said "You're fast"
I said " I'm faster than you can imagine, my turn now".
I hit him with a punch. My hand goes through his belly.
Douma said "You're strong too"
*Meanwhile*
Shinobu said "is he a human? He literally dodged every attack from Douma and his hand went through his belly."
Kanao said "I have the same question too sister."
Douma continuously tried to hit me but I dodged every attack. His blood demon art was very strong but it seemed to have no effect on me.
I said "Wanna know something, Douma?"
He said "Sure"
I said "This whole time, I have been playing around with you"
Douma gets shocked.
Shinobu gets shocked
She said "P-playing around? Is he that strong"
I said "Time to get serious"
I used my signature technique, kamehameha. Both Kanao and Shinobu get shocked seeing this attack for the first time. It hit Douma in no time and only his body with his head was there.
I said "Feel the pain. The pain that I get, I have no time to play around now. Time to finish this right here." I cut his head with my 2 finger sized nichirin. He dies. The Upper Moon 2, Douma dies. Everyone, Akaza, Shinobu, Kanao, Kokushibo, all were shocked. I alone killed Douma. I reached Kanao and Shinobu, I said "Kanao San, Inosuke's alone, you should team up with him" she said "but, I can't leave my sister like this." I said "Dw, I'm here to take care of her. You go". She goes to find Inosuke. Meanwhile I am with Shinobu,
I said "Are you okay, Darling?" I went closer to her, grabbed her and healed her (with my God KI) she got healed, I gave her a senzu bean, she ate that and got healed as if nothing happened to her, she asked me "Do you love me?" I said "Yes." She grabbed me and kissed me. I wasn't able to speak. She said "I love you too, honey." We had a talk Abt how we both fell in love with each other but hid our feelings. She also asked me "Are you a human?" I said "My species is the same as humans, but we just differ in power" she said "That means you're a..." I said "yes, I'm a Saiyan, and not just any Saiyan, I'm the descendant of the greatest hero in the universe, Son Goku." She understood how strong I was and making me as a part of her was the best decision. She said " I'm glad that I got someone like you in my life. I love you", I said "me too darling, I love you too, but promise me one thing, if you stay and love me forever, I promise to protect you and love you forever too." She said "I promise to never leave you, honey" I said "so, I promise you too, darling" Then I said "why don't we move on and save others?". She said "sure honey." After saying that, I got up and grabbed her to get her up too. Then we moved on, killing every demon one by one, Akaza, Kokushibo, Nakime. Kaigaku was already killed by Zenitsu. Everyone there was shocked to see how strong I was. By the time we encountered Muzan, everyone got to know that I was no regular human, I was a Saiyan. I requested everyone to stay aside and watch me fight, because I didn't want anyone to die.
_The Final Battle begins_
It was him, Muzan, in front of me. He said "You alone, will defeat me? Hahahaha, impossible." I said, "Time will say what's impossible and what's possible, for my friends just to keep them happy, I did everything, don't waste my time anymore and start this Fight already" Muzan said, "If you say so *screams out my name*" He attacked me first, it was a large attack, but I dodged it. I said "Let's see what you got, KIBUTSUJI MUZAN!" He hit me with like 50% of his power, I wasn't able to dodge it but I resisted it with my strength. That attack tore some parts of my clothes, but I never gave up. Hashiras were shocked to still see me standing. I said "Muzan, wanna know smth?" He said "what?" I said, "This whole time, I was just playing with you." Muzan got shocked and angry. Shinobu said "Nah, not again." I shouted "HAAAAAAAAAAAAAAA!! The walls of the castle were shaking hard, finally it happened. I transformed into Super Saiyan 2. I said, "It's been a long time since I used this form." Hashiras were just standing there, shocked. Muzan said "You, what are you?" I said "I'm the descendant of the Greatest Hero In The Universe, Son Goku." He had no words, he was just standing there. I said "I don't want anymore destruction, I'll end this quickly." I used my kamehameha again. It damaged Muzan really bad. I fought him till the Sunrise. When the Sun was about to rise, Muzan tried running away but I caught him tight. He was trying his best to escape, he damaged my hands and even he transferred his cells into my body, at the last moment, Muzan disintegrated, everyone thought that it was over, until I started screaming in unbelievable pain. Turns out that the cells Muzan transferred into me were trying to take over my body. My body was fighting with Muzan's cells to eradicate them. Everyone was confused Abt what was happening. Shinobu instantly understood what was happening and ran towards me and injected me with the Antidote. After some painful moments, I killed Muzan's cells in my body. After that I said "Did we win the battle and defeat Muzan?" Tanjiro said "Yes, we did." Shinobu was glad to see me in a good condition. She hugged me and grabbed me tight. I grabbed her back. She said "I love you Honey, if you wouldn't be there, I would've died". I said "I love you too, Darling, you're my everything, I can't afford to lose you" Mitsuri asked "Huh, what's going on here?" I said, "If I have to say in brief, I'd say that in the fight with Douma, I saved her life and proposed her, since I had a crush on her and so she agreed to be a part of me." Everyone there was shocked seeing that Shinobu is now mine. But they also congratulated us for the fact that we became couples. They wished us to be the best couples ever. I said "Dw guys, I promised to protect and love her, so she promised me to love me too, forever" Shinobu smiled at me, and so did I. Gyomei said "Thx kid, without your great power, lives of many would have been gone, and we might not even win the battle." I said "It's alright, Himejima San, it's my wish to protect all of you guys, just so you guys can stay happy, because my happiness lies in all of you, I gave my best to protect all of you, especially her" After saying that, I kept my hands on her. She smiled and I did too. I said "So guys, are we gonna have a party for our biggest win in the final battle where everyone survived?" Everyone said, "Yes!" I said "What are we waiting for then? LET'S GOOOOOOOO!" We started walking towards our house again. In the end, no one died, except for Oyakata Sama (Ubuyashiki). When we returned home, we had the biggest party ever. After the party, me and Shinobu merged our houses, since we lived in the adjacent rooms. After this, we all settled and had jobs. I was already a school student, Shinobu joined a college. Mitsuri and Obanai opened a restaurant and so on. And our Demon Slayers became Sleeping cells just like the suiside squads. We fight when danger approaches, Otherwise we live normal lives. And from that day, Me and Shinobu as couples, and others are living a happy life.
