Our Multiverse Adventure as Gokaigers

I was walking toward the direction the Urokodaki-san gave me and saw a town, (Man, it must be already noon let take a break in the town near.) As I was walking inside the town, I asked the first person I came across "Excuse me is there a restaurant near here."

"Yeah, go straight and then turn left after passing a house with a red roof you'll see a restaurant. It's fairly popular in this town" He answered while pointing east.

"I see thank you." I said as go in the direction the man gave me. And after I reached the restaurant, I heard "Delicious!" (No way, is that...) And I went into the restaurant I saw Kyojuro Rengoku in his glory with a haori with his signature flame-patterned, eating a bowl of reman with chopsticks.

I walked toward him and said, "Perdon me but is this seat taken." And he replied with his overly enthusiastic yet polite voice "Not at all, please sit!!"

"Thank you, by the way are you a demon slayer?" I asked as I take a seat in front him.

"Oh, you know about demon slayers. Yes! I am a demon slayer. My name is Kyojuro Rengoku, you can call me Rengoku. Nice to meet you."

"Nice to meet you too. My name is Ren Kosuke, you can call me Ren. I am training to become a demon slayer before attending the final selection."

Then a waiter come and asked me "What would you like to eat sir?"

"I will have a tamagoyaki with rice and spicy miso soup, oh Rengoku-san what would you like?"

"Hun? me?" as he tilted his head and pointed at himself." Yes, I want to treat you something as a proposal of our friendship."(Thank you Master Urokodaki for giving me some cash.)

"Then I won't be polite." turned to the waiter and said, "I would like another bowl of reman."

"Yes, coming right up." the girl said as she leaves.

"So Rengoku-san can you give me any tips for the final selection from a senior to a junior."

"Humm, be alert even when you sleep and remember your teaching and you'll be fine"

"I see, Thank you for the information." "No problem, so are you going to this year final selection?" "No" I said as I shake my head "I going to train more and join next year selection."

"Umu, if you know you're not ready then don't go. It's good that you know your limit, but you should some time take risks. After all life is unpredictable." He said. "Yes!" I said as the food gets here.

"Here is your tamagoyaki with rice and spicy miso and a reman bowl for you two."

"Thank you." Rengoku and I both said it.

"You're welcome, please call me if you need anything." she said as she leaves.

"Rengoku-san lets' talk after we finish eating"

"Sure"

After finish eating

"Rengoku-san can you tell me where you're headed, ah it fine if you don't want to"

"No, it's ok. I'm heading to the village northeast of here. There has been rumors that people have gone missing and the Demon Slayer corps has sent me to investigate. Well, it's time for me to get going. It was nice meeting you Ren." he said as he leaves.

"It was nice meeting you too Rengoku-san Good luck on your mission!" I shouted.

"Well time to hit the road." I said as I walked outside of town toward west.

I walk along the road and after running with full speed all afternoon, I reached the base of the mountain where Jigoro Kuwajima, the former thunder pillar lives in the evening.

I climbed the mountain and reached the top. Then I heard a noise

SWIFT

I immediately dodge and then strike the rocks I couldn't dodge with the hilt of my katana. But a few small rocks hit my face.

SMACK

"Ahh!"

"Fuhahaha, so you're the kid Urokodaki send. Not bad, not bad at all but your reflexes need some work. Anyway, my name is Jigoro Kuwajima. Nice to meet ya kid.

(Tch, if those rocks were demon nails or their blood demon art then I would be dead. Darn it, I still need to get stronger if I want to live.)

"I know that's why I ask master Urokodaki to recommend me to you. I heard that the thunder breathing is about speed and reflexes that's why I want to learn it. I know that mastering two breathing style is near impossible, but I want to try. That is why please TEACH ME!"

"I see, I see. But will you be able to survive my training I'm quite strict ya know.

"Bring it on, old man. I'll survive whatever training you give me" I said getting all fired up.

"Hahahaha very well ya better not regret it. Now follow me."

I follow him as we went deep inside the mountain forest after walking for like two hour he turned around and said "Now I want you to stay inside the forest for an entire night "

"Hun, that's it." I asked. "Of course not. I'm going to throw rock at you at random times and you'll have to dodge or block it because I won't be holding back." he said and disappear.

"What! Even after all the training my eyes couldn't keep up with him. Well time to wait. Wait a second isn't this similar to gon and killua training in hxh. I guess it doesn't matt... SHIT!"I said as a rock hit my head.

And over the night I keep getting hit with rocks over and over again. And not just one at a time but multiple rocks from different direction at the same time.

The next morning

"So how about it boy, ya ready to give up?" he said with a smug grin.

"Not one bit you shitty old man. I will complete this training and wipe that smug grin off your face!" I said and pointed my finger at him while getting up.

Day after day for one month I trained with the old man all night and in the morning, he strengthens my leg muscles and specifically swift strikes, and make me dodge as he strikes me with his full speed.

SWIF

CLASH

CLANG

Dozens of rocks fly toward me with some follow the big rocks with small one. I strike the small ones with precise thrusts and doge at light speed as I change my breathing style to thunder breathing.

"Your open kid." I heard behind, and my reflexes kick in. "First Form: Thunderclap and Flash"

and move at lighting speed, draw my katana, strike the opponent and he blocked it.

CLANG

After that I Immediately kicked him in the chest. "How's that for a kid."

And he throws his cane at me.

"Hey, watch it old man you don't have to be petty about getting kick."

"I'm not petty! If it wasn't for this wooden leg, I would be kicking your ass right now"

"HaHaHaHa Sure, everyone is allowed to dream" I shrugged.

"Sigh, you're going to break my hip one of these days kid."

"Anyway, are you ready for this year's final selection at Mt Fujikasane."

"Yeah, I think I've already prepared enough for the selection."

"Very well. Then you should get going the selection is in a week and it will take you 3 days to get there with your normal speed. Go pass the test and make me and Urokodaki proud."

I grinned and said "Of course, I will, wo do you think I am."

"See you later old man!" I said as I ran away while waving.

4 Days later

(Sign, it's kinda boring when nothing happens. The sun is going down soon, and I don't see any place to sleep. Well tree branch here I come.)

At night

Chikk. Chikk

I hear something and open my eyes and I saw a shadow moving at a fast speed.

(That speed is too fast for a normal human. It's either a demon slayer or a demon. It's coming this direction!) I ready my stance to draw my katana the moment that moving thing get in front of me.

(NOW!) I jumped for the tree to the thing that is directly below me.

CLANG

My katana got blocked and I looked at the thing that blocked it as the moonlight reveal it's figure.

There I saw a girl with purple hair wearing a dark purple standard Demon Slayer uniform with a white haori that have butterfly wing patterns and a light purple butterfly ornament.

(She's beautiful.)

"Oh my, I can see that you're not a demon so can I ask why you attack me boy." she said with smiling with her eyes closed.

"...."

"Don't you have anything to say for yourself?"

"....."

"This is your final warning."

"....."

"Give me a reason at least." she had a vein on her head.

"Sorry, I thought that you were a demon and I'm not a boy you and I are about the same age." I replied after getting out of my thought.

"I see. I see. Because you thought I looked like a demon you tried to strike me down well that's just uncalled for isn't it." she said while ignoring my statement about our age.

"I see you have a katana. Are you a demon slayer?"

"Ah, no I'm not. At least not yet. I'm going to this year final selection." I answered.

"Are you fine being a demon slayer even if it means dying?" Shinobu asked seriously.

"Of course not!"

"Then why... "

"What I mean is that I have no intension of dying because I'm going to survive and kill all the demon!" I answered getting all fired up.

"Then you wouldn't mind if I strike you back with my katana, would you? Consider this as a test before the final selection to make sure you don't die." she said as she charged at me with great speed.

"Bring it." I said and took out my own katana to block.

CLANG

"Is that all you've got." I exclaimed with a grin.

"Ara, this is nothing much. Didn't I tell you consider this as a test. If you can't even touch me, how do you expect yourself to kill a demon." She replied and pushed me into the forest, break off and jumped into the forest.

"Fine! then, if you want to play games, let's play games." I said calmly as I ready my katana.
