Chương 40: Bound by Blood

Me and my dad were working tirelessly trying to make a seal that would be able to entangle two siblings together through the similarities between their chakra signature. The effects of a seal like this would be pretty simple but also really profound. It would allow the two siblings to talk to each other through their thoughts over a long distance, project their feelings, and also send out an SOS signal that alerts the other sibling to their location.

Ever since the academy sped up our curriculum and decided to graduate us 3 years early, I wanted to have a seal created to help Kushina, whether she is shipped over to Konoha to become their next jinchuriki or she stays at home and it doesn't happen like canon.

"Either way, war is on the horizon, and I want to make sure I have at least some way of protecting Kushina," I said, my eyes steely as my kanjogan unconsciously showed itself.

I turned back toward my dad and continued to watch a grandmaster sealer work on this seal. It had been around a year since I asked to start making this seal with him, but with the upcoming war, there were more and more meetings between the clans and Lord Third, so we haven't had a whole lot of free time to really sink into this project.

Fortunately, my dad has always been a reliable man, so we began working on the seal around 3 months or so ago. I was learning a bunch of different little nuances while my dad would also give me little out-of-the-box tidbits here and there.

That's also the thing I have slowly but surely started to figure out about fuinjutsu as well. In order to be good at sealing and creating sealing, you need amazing parallel processing power and also a mind that can think out of the box to find solutions for different problems.

On top of that, the amount of knowledge packed into each tier is crazy. It's like if you were to only know how to add 2+2, at the base level, and then you jump up a step in the mastery of fuinjutsu and now you're doing order of operations. After you master that, you move onto quantum physics; you get the point.

"You see how I made the line at the end of this kanji? If you were to angle it a little more downwards, you would end up blowing up the seal because you would be telling the seal to cycle the chakra back inside itself. That works well for, say, explosive seals, but when you're putting it on your body, you don't want it to do that," my dad explained. Nodding along, I filed it away to study later.

"Honestly, if you don't have perfectly steady hands and writing, I'm almost convinced you could make a black hole accidentally."

"The only problem with this seal is that, while we're almost done with it, we need something that is more potent and binding than just ink with chakra in it. What do you think we could use?" My dad looked at me while I thought about it.

*ding*

"We could try using our blood to create the seals." Smiling, my dad ruffled my hair.

"You're absolutely correct in that assumption. The only thing that I'd say we need to change is that we need to mix both of your blood together. In order to get the effect with your chakra resonance that we want, you have to make sure your blood has a place to resonate to."

"That makes sense. Without a second signature to send to, you would essentially just be playing catch with no one."

"Alright, you go grab Kushina and bring her out to our workshop. We'll explain what we want to do and if she's okay with going through with it as well."

Grabbing Kushina and bringing her out to our backyard shed, we had her sit in one of the chairs while my dad explained everything to her in detail: how it works, what it will do, where it will go, and so on.

"This whole idea was your brother's idea as well. He brought it up to me for the express idea that you both will be able to have each other's back no matter the distance that is between each of you, just as siblings should be," my father said with a warm smile as he looked upon his two great children.

Kushina was looking thoughtful for a minute before she agreed to getting it on herself, stating, "I'll need some way to know where you are to save you," making me chuckle as we sat across from each other and stuck out our right hands, dripping some of our blood into a bowl.

"This may burn a little bit for you guys, so just be mindful of that," my dad spoke from his experiences, giving us a fair warning.

He started with me first, and as he started to make the seal, my hand tingled with a warm but comfortable feeling. It was one of the weirdest sensations I had ever felt up to this point. As he was putting on the finishing touches, I got a little dizzy, but it was nothing terrible.

Seeing her brother going through the process had given Kushina a little more confidence, and she didn't move an inch as dad was applying the seal to her right hand. Finishing up on Kushina's seal, a foreign feeling overcame me as I looked up at Kushina, who also did the same with my eyes wide open.

I could feel Kushina's chakra as if it were connected to my brain. This seemed way more intimate than the powers of the M E even though the uses are more vast than this seal. I could feel her restless chakra at the new experience, her hard-headed personality, the sureness in herself, and the love she held for all of her family.

Looking at the seal, I infused my chakra and will into it and started to speak in my mind.

"Kushina, can you hear me?" She jumped out of her seat and landed standing up before appearing in front of me and clobbering my head.

"Don't scare me like that again! You should've told me you were going to speak through the connection," she said, looking at me with that intense light in her eyes and her hair floating way above her head.

Chuckling a little, I put my hands up and admitted defeat in this battle.

"You try it this time, Kushina," I encouraged her to see what it felt like.

"CAN YOU HEAR ME SHI?" she asked in a very loud tone, almost unsure whether she would be heard or not. Wincing, I thought, 'Yep, that's my little sister, alright.'

"Yeah, I can hear you just fine. I'd say that this seal is an amazing piece of work, honestly."

"Yeah, maybe the old man is useful for something besides eating the food every dinner." We laughed at that, all the while our dad looked on in confusion as we talked to each other through the link we had going.

"Alright, try to actively send some of your emotions through the link, and I'll send some back to make sure that aspect is working as well." Kushina nodded and sent an emotion that resonated very deeply at this point within her. That emotion being appreciation, smiling at that, I sent back love to her, letting her know that even if everyone turned on us, we would still have each other's backs.
