JJK : With a Shotgun in Jujutsu Kaisen

*Blurb*

Letting go of the final breath that Gensui had in himself, Gensui continued sinking into the almost neverending Sea of Water he was in and started drowning.

Silently he stopped resisting as he felt himself be dragged down and down almost as if something was trying to drown him out and just before everything went black he saw something-

.

".....sui"

"Gensui!"

"GENSUI WAKE THE HECK UP" ??? Yelled, jumping up and slamming her elbow on Gensui's stomach.

"Bu-fah!" Gensui yelled as he felt this sudden blow on his stomach and saw a pair of eyes staring at him rather innocently from his chest.

"Good Morning my Brother!" Tsumiki said rolling the r getting up and taking her elbow off his stomach. 

"So is it the usual routine Tsumiki??" Gensui asked.

"Yup!" She cheerfully replied.

"You were making all sorts of noises so I just had to wake you up!" She continued.

"How many times have I told you not to wake me up when I'm like that, I might swing my hand the wrong way and your hand will suddenly be in a plaster someday," Gensui said talking about his nightmares.

"Well, you can't just expect me not to wake you up when you're having a nightmare, can you?" Tsumiki asked.

"Yeah yeah don't worry I haven't forgotten anything, You're just that kinda Annoying," Gensui said.

"Stay that way and you will never get a girlfriend" Tsumiki replied.

"Oh, I almost forgot. Today is recycling day, right? Make sure to throw out the 20 love letters that are in the corner of my room as well, They're in a bag specifically for you to throw away" Gensui said, sending a small grin toward his sister.

"Ah yes even more Poor fishes were gathered towards the Net eh" Tsumiki replied.

"HAH? You're saying this as if this is my fault somehow!" Gensui asked.

"Then who else's will it be Onii-Chan~" Tsumiki replied.

"Somehow I am getting the feeling that your personality has warped quite a lot over the past year," Gensui said staring at his sister.

"Sigh, stay that way and-" 

"Do you only have a single dialogue Miss Npc?" Gensui quickly replied.

"And now you'll get mad when I repeat my dialogue" Tsumiki replied.

Popping a vein and letting out a slight grin Gensui said, "Ah I'm suddenly feeling like I want to wake our little bro up" Creating a Glock with a Blank loaded into it.

"OI OI OI OI OI I can see you grabbing onto something crrraaazyyy aren't you Big Bro? You're using that BS whatchamacallit that I can't see again! Don't think you can go trouble Megumi so freely Demon King" Tsumiki said raising her arm above her head like an Anteater.

"Oh yeah Miss Anteater? Try and defeat me then" Gensui said and jumped over Tsumiki grabbed her waist and started to tickle Tsumiki on her sides.

"Wha-Wait wait just unfair you know I'm weak to that," Tsumiki said laughing as tears started to well up near her eyes.

When I lost my Family- My Grandparents then my Parents..... I was devastated but that fortunately didn't last long because I had Yuki-sensei in my life, she was comfortable to be around and I didn't feel scared as long as she was around, these feelings weren't towards my well-being, but rather towards hers- Because she was so strong I didn't worry about the world because I knew that no matter what happens she wouldn't die and be separated from me.

Of course, I knew someday my training would be over and she would go away but I knew it wouldn't be a permanent Farewell... although when she did go away I protested at first I soon overcame it since this was something knew for a long time.

Without worry, I lived even after she left but what devastated me the most was when I was introduced to them....

The Fushiguro Siblings.

Satoru-sensei told me that I'd be living with them until I started high school, so 3 years which wasn't a big problem but from the back of my mind worry started to bloom, I wanted to stay with only those who were strong so they never leave me again and these two?

Weak.

The Kid- Megumi although he had even more potential than Me and Satoru-Sensei somehow didn't want to train, what a Bum.

But I was comforted with the knowledge that he will still learn the basics of fighting to protect himself as much as he can.

But the sister? A Non-Sorcerer... I already started distancing myself from her because in case she got hurt I wouldn't feel as sad but.....

[*Splash*

"Ah sorry I wanted to give you milk but you had Airpods on so I kinda..." Tsumiki said.

"Threw the entire glass on me somehow?" Gensui asked.

"Yeah yeah, that..." She meekly replied]

[*BAAAM* *BAAAM* *BAAAM* *BAAAM* *BAAAM* 

*Thud* *Thud* *Thud* *Thud* *Thud* *Thud* 

Gensui immediately ran towards Tsumiki's room and his worried eyes immediately turned dead as he saw the girl sitting around a bunch of dusty cardboard boxes with their contents overflowing all over. 

"Let me guess you tried moving those, from an oddly high location and threw them all down and also fell?" Gensui asked with a slight smile.

"Uhm Err Eto teeheee?"]

On any other day, she was the paragon of discipline trying to be a strong person for her little brother and seemed to be able to relax now with me in the house acting like a Big Brother figure to the both of them and with each and every day..... day by day, week by week, month by month and year by year we became similar to actual siblings.

For the longest time I have protected them against Curses and Humans alike, From all dangers and harm so that they don't lose even a strand of hair while I am around, losing my family in front of me is something I don't wish to even my enemies....

"Why...."

"Why the hell are you here Tsumiki?" Gensui asked looking behind him as Tsumiki looking angry stood behind him with a paper in her hand, vanishing.

A Talisman was created specially by Satoru for Tsumiki to protect her in case she gets into harm's way.

A ridiculously strong attack that is on par with 50% of his Hollow Purple made with the help of a Binding vow which broke the Giant Curse's Domain to pieces.

"I had the worst gut feeling that I ever could have had so I came back to check on you.... and now that I am here I'm just so glad that I came," Tsumiki said with a smile.

However, Gensui immediately asked the most important question, "Tsumiki... why could you see the Domain?" Gensui asked with a dumbfounded expression.

"That's....." Tsumiki hesitated.

"A few weeks ago I started seeing Curses....." She muttered.

"And-"

"NO NO NONE OF THAT MATTERS RIGHT NOW!" Gensui screamed interrupting Tsumiki.

"GO, LEAVE RIGHT NOW," He said in desperation.

"Sigh, If you keep interrupting girls you won't get popular you know Onii-Chan!" Tsumiki said with a grin and walked past Gensui.

"Wait" Gensui whispered.

"WAIT, DON'T GO"

"I'LL KILL THE CURSE, MYSELF, DON'T APPROACH IT," Gensui said flipping over and crawling towards Tsumiki who was moving a little too fast towards the Curse, or rather it was Gensui who was moving too slow.

Gensui's eyes immediately started to blur and darken as he started losing consciousness due to blood loss and the pain he was suffering through.

'HEART, LUNGS, LIVER, NERVES' Gensui thought trying to keep himself conscious.

'HEART, LUNGS, LIVER, NERVES. HEART, LUNGS, LIVER, NERVES. HEART, LUNGS, LIVER, NERVES. HEART, LUNGS, LIVER, NERVES. HEART, LUNGS, LIVER, NERVES. HEART, LUNGS, LIVER, NERVES. HEART, LUNGS, LIVER, NERVES. HEART, LUNGS, LIVER, NERVES. HEART, LUNGS, LIVER, NERVES. HEART, LUNGS, LIVER, NERVES. HEART, LUNGS, LIVER, NERVES. HEART, LUNGS, LIVER, NERVES.' Gensui with each fist smashing into the ground pushed himself through the pain and walked towards the distancing figure of his sister.

"AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA" The Giant Curse screamed towards Tsumiki who was walking towards it with all the fear in the world plastered on her face as she glanced over towards Akaji and pointed at Gensui to Teleport him out of this location.

Akaji upon seeing this dropped his Simple Domain as the others realized they could move again, Akaji immediately ran towards Gensui which turned into a crawl as the aftereffects of using Teleport within the Gaint Curse's pressure weighed on his body causing him to weaken by a lot not only that but the others were too tired to even move other than Mei Mei who could not add anything as she could also crawl at the same speed.

The Curse looked to the side where the other Sorcerers were and was about to shoot an attack at them but its head suddenly moved towards Tsumiki whose Pupils were glowing with a Dark Flame which as time went on the fire increased.

"Monster.... Look.At.Me." She said.

"Tsumiki you don't understand what's happening right now, ESCAPE! NOW!" Gensui yelled still chanting HEART, LUNGS, LIVER, NERVES in his head to move forward.

"No... I totally understand what is happening right now..... Long have you saved me, Big bro..... Now it's my turn" Tsumiki said as both of her eyes started glowing with a Black Flame creating an unknown effect that caused the Giant Curse to look toward her.

"WWWWWWWWWWWUUUUUUUUUAAAAAAAAAAAAAAAAAAAAAAAAAAAA" The Giant continued screaming as its open mouth seemed empty Darkness glew with light, nearly blinding everyone as it shot that white light towards Tsumiki who took it head on.
