" Well this is unexpected," I said while looking at the two giant wolves in front of me.
After drinking the potion both Cerberus and Fenris somehow increased in size to such a point that now they both are big enough to destroy buildings.
Both of them are more than 4 meters tall and look menacing as hell.
*GROWL*
Fenris and Cerberus growl as towards us as they move there huge bodies towards our direction. Slowly they move towards me and Inosuke ready to eat us alive.
They both open there mouth and I see their sharp rows of teeth first-hand. There mouths being big enough to swallow me and Inosuke whole.
'Did this thing change their behaviour? I don't wanna knock them out at least I don't wanna be the one to hurt them.' I thought while looking at the two menacing beasts in front of me.
But then I noticed something.
'Ohh this is why.' I thought while moving my hands forward.
"Nii san." Inosuke said with confidence.
'Hmm so he noticed it too, huh. I expected Nothing less from my brother.' I thought as I suddenly moved beneath Fenris as Inosuke did the same for Cerberus.
I activated Wolf Breathing and extended my claws and reached towards Fenris's belly.
*1 Minute Later*
"Who's a good boy? You are yes you are." I said while the 4 meter tall snow white wolf was on the ground rolling happily on the ground while I was using my claws to scratch it's belly.
What? A Wolf has it's need and mine also had it's own. As much as Fenris liked to act cool and emo in front of Cerberus and other members of the pack he loved belly rubs and I loved giving them.
Inosuke was doing the same for Cerberus. Well it was more like they were both hugging and tackling each other, but who am I to judge?
" Hey Fenris can you become smaller." I asked the Huge wolf in front of me.
Fenris made an expression like he was in deep thought and then suddenly his body started to shrink.
After a few moments, Fenris looked as small as an adult German Shepherd from my old world.
" Inosuke ask Cerberus to do the same."
After a few seconds, we now had two normal wolves in front of us and both of them were nuzzling their heads against us.
" Okay, that does it for the crazy experiments for the day.Now let's go to sleep."
" Why? I wanted to play more," Inosuke said while scratching Cerberus's head.
" Nope, we're going to sleep. We need to move out of this place as quickly as we can tomorrow." I said while patting Fenris.
" Fine," Inosuke said while making a grumpy face.
After that, we just slept in the forest while hugging Fenris and Cerberus.
*The Next Day*
We were now taking Gramps back to his old shack on the mountain. We tried to talk him into staying in the village but this old man can be as stubborn as Inosuke.
" Hey, Inosuke get Gramps inside the hut."
"Sure Nii San."
" Fenris come here," I said as Fenris moved towards me.
" I need you to go towards the mountain and ask the other wolves to check in on Gramps every few days and also ask them to bring whatever small animal like rabbits or any extra game they find for Gramps to eat every few days. Now go and come back quickly."
If it was any normal wolf pack then I couldn't trust them enough to obey my orders but all the animals on the mountain had far more intelligence.
' Let's get inside the shack.'
" Hey, older brat come here," Gramps said.
"Listen to me first old man. You need to take care of yourself more. We've asked the villagers to check in on you every once in a while so don't be rude to them."
"Also eat a lot you need to put some meat on your bones if you want to survive."
"After 2 or 3 months you may also receive some letters from a few crows. Those will be from us so you can use them to write something like ' Hope you're okay' or stuff like that."
" Wait we're getting crows?" Inosuke asked with a curious expression on his face.
" Oi I'm the older one here do why is it that I'm getting lectured by you brats? Whatever just get that chest to me." He said while pointing towards a corner of the shack.
"First tell me are you feeling okay right now? We can still take you back to the village."
"Tis but a scratch." Gramps said while pointing at his chest which was 90 percent covered with bandages.
I decided to ignore the old man who didn't act his age.I moved around the shack and found a large chest in a corner. I picked it up and placed it near Gramps.
Any other kid my age would have his head buried in the ground from the weight of the chest but Gramps was already used to me and Inosuke having abnormal strength.
Gramps opened the chest and took out a pouch.
" Take these coins. Don't refuse, I already know that you both are trying to become Demon slayers but what you don't know is that the life of a demon slayer is not of glory but pain and suffering."
" I never had any children but for me, you both are my grandchildren so take care of each other you brats."
" But what about you? What are you going to do without the money?"
" You've never been a smart one have you Inosuke. I live on a fucking mountain. I eat what I grow."
" Still Inosuke has a point. Take some of the money back just in case you need it for medicine."
" If those villagers don't come to check on you just tell us. I'm going to make them run for their lives." Inosuke said while cracking his knuckles.
' Phew. At least he is better than his canon version. My little brother is too overprotective.' I thought while letting out a sigh.
" I never thought that I would be giving these to anyone let alone two brats but here you go," Gramps said while taking out two katana from the chest.
" These were given to my ancestors for their services to the Tsugikuni clan. These blades are said to be the only weapons capable of killing the demons. I kinda made the connection between your strengths and Breath styles a while back."
I was kinda expecting the swords to be connected to the Tsugikuni clan. Those guys sure love to leave their marks wherever they go.
I grabbed a katana and passed the other one to Inosuke.
'Hmm, these didn't change color when grabbed by us. Well, we haven't trained in actual swordsmanship. But I and Inosuke are most likely strong enough to participate in the final selection.'
" Okay, Gramps do you know anything else about the Demon slayer corps?"
" Well, when some of the members of the Tsugikuni clan turned 14 they were sent to a mountain to the North of here for something called the final selection."
"Can you mark it on a map for us?"
"Sure."
' Well, that makes sure that we don't have to wander around in search of a random demon slayer to ask for directions.'
"Here." Gramps handed a map to us.
"Make sure to reach the mountain before the start of winter. The exams are held at the mountain during that time."
"It will take us a couple of weeks to get there."
[*Ding*]
[For not being completely useless and being able to find the place for the exams to be held, you have received a gift]
[Recieved 'Master Kenjutsu guide']
' I'm just gonna have to ignore the System for some time. Well, I already know most of the sword moves for my breathing styles but it will still help to practice with the swords.'
'It will take some time to get used to swords but most likely we would've reached at least the basic level until we reach the final selection.'
'I can't wait to get my hands on a good Nichirin blade'. I thought while moving my hands along the sword in anticipation
I then saw Fenris enter the shack.
"Okay, Inosuke it's time for us to go. Say goodbye to Gramps."
Then I and Inosuke both hugged Gramps and placed the swords in their sheaths which for some reason were very well designed unlike the swords and were completely white and had a golden sun made on top of them.
'Hmm it seems like these swords don't belong with these sheathes for some reason.' I thought while rubbing my hand on the Golden sun mark on the swords.
We then bid farewell to Gramps and started going toward the North with Fenris and Cerberus in tow.
"We gotta train our swordsmanship while traveling Inosuke. Just wait till we get to join the demon slayer corps. We will get to fight some of the strongest beings on this planet." I said while laughing with my brother and moving towards my exciting future.
