In the Pokemon World, Sasuke was sitting on the shrine's stairs, he didn't sleep at all but he let his students sleep.

Sasuke: The league... it's near.

He bring up his badge case full of his Uchiha badges while inspecting them carefully.

When morning rises, Sasuke was training his Uchiha blade near the shrine.

Sasuke: Uchiha Style: Halo Dance!

Sasuke shots some fire slash out of his blade, hitting some tin cans down and burn it to crisp.

Sasuke: I've learn something about Shisui's jutsu, I guess this can be my advantage.

Suddenly a moving shadow went passed him that made him quickly looking up but it was gone.

Sasuke: What was that?

Then a Noivern appeared above him then flies down to Sasuke before stopping right in front of him.

Sasuke: This Noivern... Ash's Noivern.

???: It sure is!

He was suprised that 3 person was climbing down Noivern's back, it was Serena, Clemont, and Bonnie.

Bonnie: Hey Sasuke!

Sasuke: What? Serena? Clemont? Bonnie?

Serena: We were looking everywhere for you, good thing Noivern notice your scent.

Sasuke: Huh? How did she caught my scent? I didn't even met her.

Clemont: With this!

Clemont bring out Bunnelby's pokéball, Sasuke though for a moment before realizing he was on adventure with Bunnelby before so his pokéball would always got his scent.

Sasuke: I see, clever move.

Clemont: Hehe!

Serena: We were worried when you flew away without us knowing.

Sasuke: Oh, it was a long story. We can talk more inside the shrine. *Walks to the shrine*

Bonnie: Wow! Cool shirne! Is this yours?

Sasuke: ....Maybe

In the Shinboi World, Sai's team and Lee's team was on their way back to the Hidden Leaf Village.

Denki: That was one heck of a mission we been through there

Ash: True, but atleast we got what we want now. It's not a big deal anymore.

Behind the group was Pikachu and Sylveon, somehow he was still in top shape after he was revived but Sylveon on the other hand was too tired.

Sylveon: *Pants lightly*

Pikachu: Sylveon? Are you alright? You seem very tired.

Sylveon: Yeah, I just feeling a bit drowzy, that's all.

But suddenly she starts to collapse to the ground, but Pikachu manage to catch her and put her head on his chest.

Pikachu: You're not feeling okay, you have to rest yourself.

Sylveon: 0///0 I-I... well... I'm....

Pikachu: *Puts his paw on her head* And you're having a fever, must be the heat stroke.

Sylveon: B-But... I...

Denki took notice of what happened and he rushes to the pair and bring out his aid kits.

Denki: Hey, what happened to Sylveon?

Pikachu: Seems like she is tired, maybe a tiny heat stroke.

Sylveon: *Blushes* P-Pikachu?

Denki: Here, you can have these.

Denki bring out some energy pills for Sylveon before Pikachu took some.

Pikachu: Thanks, this might get her strength back.

Denki: Hopefully.

Denki rushes back to the group while Pikachu gives Sylveon the pills for her to chew.

Pikachu: There, how do you feel?

She went silence for a bit before she starts to get nausea and starts getting light headed by the taste.

Sylveon: YUCK!!

Pikachu: I know it taste bad, but atleast it gives back your strength.

Sylveon: I might not eat another energy pills forever...

The two rushes back to the group but everyone can see Lee was grunting while lifting Sai on his shoulder.

Sylveon: Is Lee-sensei alright?

Metal: Papa never been like that, maybe he's too tired?

Sai: Umm... Lee-san?

Suddenly Lee throws Sai up into the air before he lands on his back. Lee was actually planning to give Sai a piggy back but the rest of the group that saw this went completely silence.

Naruto: (Huh? This seems familiar...)

Ash: (What in the name of Arceus is this?)

Sylveon: (Two old person doing a piggy back ride?)

Pikachu: (Is that even necessary?)

Metal: I see! This is a training, right!?

Lee: Hehe! With this we can go even faster!

Suddenly Lee rushes away kicking dust at the team that made everyone coughs while Sai that was already tired out.

Lee: Hey you guys! Can you keep up with us?

After the sensei ran away, everyone that was left out was just standing still watching their sensei running away.

Pikachu: Should we follow them or something?

Ash: Honestly, I don't know.

Naruto: *Sighs* I'm going to go ahead, the six of you can take your time.

Ash: Alright Naruto.

Naruto then uses teleportation jutsu to go ahead to the Hidden Leaf.

Ash: (Naruto...)

Suddenly Metal turn his bag to the front and starts positioned himself to give someone a piggy bag.

Metal: Iwabe!

Iwabe: No way!

In the Pokemon World, Serena and her friends was looking around the shrine while Sasuke was eating rice balls with Chairo.

Chairo: Father? Are you the one that gave me this new arm?

Sasuke: Yeah, I don't want you to face the same disadvantage as I am.

Chairo: Th-Thank you, Father... *Cries*

Sasuke notice Chairo crying, he then pulls him into a hug while letting him cry on his cloak.

Chairo: *Keeps crying*

Sasuke: There there, it's okay.

He closes Chairo with his cloak so nobody notice him hugging him before Serena and the others came to him.

Serena: Hey Sasuke, me and everyone is going to go back home. Will you be okay on your own?

Sasuke: Yeah, I have my pokemon on my side so I will be okay.

Clemont: Alright, we'll leave your stuffs and some food on the second floor.

Sasuke: Thank you, I'll be home soon.

Bonnie: Bye bye!

Serena and the others rushes out and flew away by riding Ash's Noivern.

Sasuke: Well, that took care of something for the time being.

He can see Aoi came down from the stairs and puts two cups of green tea for him and Chairo.

Aoi: Here you go Master.

Sasuke: Thank you Aoi

Aoi: Anyway Master, there is something I want to ask you.

Sasuke: Hm? Is something wrong?

Aoi: What should we do with this shrine?

Sasuke took one of the tea and drinks it slowly.

Sasuke: That's the problem... I still don't know what to do with it...

Aoi: Oh...

Sasuke: We can think about it later, let's just focus on the training for the league.

Aoi: Understood.
