About a week after Jūshirō got his true Zanpakutō in Sōgyo No Kotowari, Shunsui managed to get his which was named Katen Kyōkotsu and it surprised everyone that it existed as a sword pair, a tachi and a wakazashi.
A couple of days after Shunsui had gotten his true Zanpakutō, the two were called to the dojo.
"I hope this isn't about some prank you've pulled again Shunsui"
"I haven't played pranks on anyone or chased the girls for that matter"
Jūshirō looked at his friend with a look that said "oh really" which made the other student chuckle.
"Okay maybe I tried chasing the girls"
The white-haired student sighed and shook his head.
"You're impossible my friend"
Shunsui smirked before looking up to see that they had reached the dojo.
They walked inside and saw Yamamoto sit with his back against them.
"We're here sensei, said Jūshirō"
"So why did you want us to come, Shunsui asked"
Yamamoto got up and looked at his two students.
"I asked the two of you to come because I wanted to talk to you both about your training"
"Our training?"
"You have both awakened your Zanpakutō which puts you a bit ahead of the others in your class.
-So starting tomorrow, the two of you will have a special Zanjutsu training with me to get the two of you used to your new blades. Especially you Shunsui since fighting with dual blades will take time to learn"
The friends looked at each other and nodded before bowing.
"We're ready for it sensei, said Jūshirō"
"Good. I won't go easy on you though"
"We didn't expect anything else old man, said Shunsui"
"Well, then I expect you two here after your final class tomorrow"
"SIR!"
Next day.
Their last class of the day was over and the two friends was making their way to the dojo.
"Let's see what the special training is"
"Yes"
They entered the dojo and Yamamoto stood ready.
"You showed up"
"Of course, said Shunsui"
"We do afterall want to master our new weapons, said Jūshirō"
Yamamoto nodded, pleased over the answer.
"Jūshirō, your training will be similar to what I usualy go over just a bit harder"
"Understood"
"Shunsui, your training is to first of all master how to wield a sword in your opposite hand"
"Yes sir"
So the two drew their swords, Shunsui deciding to use the smaller of his two swords and their training began.
Time passed and with each day, the two got better and better at using their new swords. Shunsui still needed to train up his left hand a bit more but he was getting there.
A couple of months had now passed since Jūshirō first meet Sōgyo No Kotowari.
He was currently sitting under one of the trees in the schoolyard, his Zanpakutō in his lap as he meditated.
When he opened his eyes, he was in the garden where he first had meet the two, his inner world as Yamamoto had called it.
"Yay Juu is back, said Sōgyo"
"Hello you two"
"Are you here to play, Kotowari asked"
"Why not"
"I have an idea, said Sōgyo
-If you win, we tell you our Shikai"
"Sounds okay to me.
-So what do you wanna play this time?"
"Tag, said Kotowari"
"No, we did that last time, said Sōgyo"
"Hide & seek?"
Sōgyo nodded and turned to Jūshirō.
"Is that okay?"
"Yes"
"Okay. We hide and you seek"
Jūshirō nodded and closed his eyes as he started to count and the two ran of to hide.
"20. Here I come"
He looked around at first to see possible hiding spots before starting to walk around.
"Where could those two have gone?"
He tried to focus to see if he could sense their spiritual pressure but had no luck.
So he started to look through the bushes and up the two trees in the area but they weren't there.
"Think Jūshirō. Where could they hide around here"
He then realized something.
"Is it that simple?"
He walked up to the pond and saw what looked like two fishes.
"Found you"
The fish moved and the two boys appeared from the water.
"You found us, said Sōgyo"
"We thought the pond was a good hiding spot, said Kotowari"
"Well, I didn't think you would hide there at first but then I remembered that when we first meet, there was a splash in the water
-Your name also means Truth of the Pisces or twin fish. And fish like water"
The boys looked at each other and smiled"
"I think he's ready, said Sōgyo"
"We did promise, said Kotowari"
They then turned to Jūshirō.
"When you call our names, I will rise like a mighty wave to shield you, said Sōgyo"
"And I will strike as fast as a lightning, said Kotowari"
Jūshirō looked at the two a bit confused but he soon seemed to understand.
"Okay. Thank you Sōgyo No Kotowari"
He then found himself back in the real world.
"Hey Jūshirō!"
He looked up and saw Shunsui come towards him.
"Hi Shunsui"
"Have you forgotten that since Kidō class was canceled, old-man Yama put in extra training for us"
"Oh yeah.
-Let's not keep him waiting then"
He got up and they walked to the dojo.
"You two ready for today's training?"
"Yes sir"
"Good. Today I want you two to spar with each other"
The two nodded and began their training, attacking and doding each other's attacks until Jūshirō heard Sōgyo No Kotowari's voice in his mind.
"Do it, said Kotowari"
"We did tell you what to do, said Sōgyo"
Jūshirō smiled and leaped back to dodge an attack before grabbing his Zanpakutō with both hands.
"All waves rise now and become my shield, lightning strike now and become my blade... Sōgyo No Kotowari"
The single sword slowly split into two thinner blades with a second blade coming out from around the middle and bending downwards towards the hilt.
A red rope with five silver talismans connected them to each other.
All three looked at the swords in surprise.
"So you have achieved your Shikai Jūshirō, said Yamamoto"
He walked closer to his student and looked at the blades.
"This is the first time I've seen dual Zanpakutō. Both for sealed form and Shikai
-You will now have to learn new styles of fighting"
"Yes sir"
"Just you wait Jūshirō, I'll get my Shikai soon enough and catch up with you, said Shunsui"
"Right"
For the upcoming weeks, Jūshirō practiced with his Shikai, trying to get the hang of fighting with two swords.
The trickiest was the rope that connected the blades which was something for him to get used to so he wouldn't step on it or so it wouldn't get tangled.
This day, he was in the dojo, training under Yamamoto's watchful eyes when Shunsui came.
"You're late Shunsui"
"Sorry sensei but I was having a conversation with my Zanpakutō and she sure took her time.
-But I did get her to tell me about my Shikai"
"Let's see it then"
Shunsui nodded and drew his swords.
"Flower wind rage and flower god roar. Heavenly wind rage and heavenly demon sneer... Katen Kyōkotsu"
The tachi, wakazashi sword pair changed to a pair of huge black curved Chinese schimitars with a red tassel hanging from the handles.
"Impressive
-Well then, now when we know that you both have dual Shikai, it will be easier for me to make the right training exercies for you two"
"We're ready for anything sensei, said Jūshirō"
"I hope you are cause your training will only get tougher from here"
"We can handle it. Right Jūshirō?"
"Yes"
"Then starting next week, these training sessions will be for mastering your dual Shikai"
"Sir!"
