It's been a year since Goku left to train. A lot of things have changed in the Soul Society. Cocoa became Ella's lieutenant, Goten became a captain, Jeff became the new lieutenant of LT's squad and LT just kept doing his job.
LT: Wow, I miss Goku. It's so silent without him.
Jeff: I know.
Ella: I kinda agree with LT on that.
Cocoa: I don't "kinda agree", I agree completely.
As they kept talking, the intruder alarm went off disrupting the peace.
Guard: Intruder alert! I repeat, intruder alert! This is not a drill!
LT: Wow someone got into the Seireitei how...weird.
Cocoa: Yeah, I thought the gate guardians were gonna stop the intruder.
Goten: I just got a message from the guards. They say the four gate guardians were defeated while trying to prevent the intruder from passing.
Ella: That is just...impossible.
Jeff: Holy crap, he must be strong then.
LT: Enough talk, let's go to check what's wrong.
They all went to search for the intruder as a young man with long hair walked through the streets of the Seireitei.
???: Wow, what a nice way to greet me after one year...guess nothing's changed huh.
Jeff: Hey...are you the intruder?
???: ....Wow, you were promoted to lieutenant. Congrats then.
Jeff: Answer my question! Are you the intruder?
???: Aww, you talk too much. Yeah I am the "intruder".
Jeff: Well, I'm gonna have to ask you to come with me.
???: No thanks, I am looking for someone.
???: Her name is Cocoa and I know that you know her.
Jeff: ....Who the hell are you..?
???: An old friend.
The young man soon left the scene leaving Jeff wondering who he was.
???: That was a close one.
Goten: Stop there, I'm gonna have to ask you to come with me quietly.
???: Oh God not again...wow you were promoted to captain. I guess things DID change after all.
Goten: ...You are?
???: An old friend. I am looking for Cocoa, have you seen her?
Goten: ...I was talking to her earlier, but I haven't seen her after the intruder alert went off. Now can you tell me who you are?
The young man showed Goten his face leaving Goten a bit surprised.
Goten: .....Welcome back, old friend. Now go and keep looking for her.
LT: Goten, did you see the intruder?
Goten: ...No I didn't.
LT: Damn, he's sneaky.
The "intruder" kept running to avoid fighting the people of the Soul Society.
???: Come on, where are you Cocoa?
Cocoa: ....Dance Sode no Shirayuki. *freezes ???'s feet*
???: ...Oh crap, wait.....damn, my feet are frozen.
Cocoa: Finally someone stopped you.
???: Oh come on, everyone forgot about me!
???: How can you forget me? It's me...Goku.
Cocoa: ...That has to be a joke. You don't even look like him.
Goku: That's because you haven't seen me for a whole freaking year! Of course I am bound to change, especially my hair.
Cocoa: You have a point there.
Goku: Indeed, now let me go. This ice is cold...obviously.
Cocoa: ...Okay. *unfreezes Goku's feet*
Goku: Thank y-
Cocoa: *hugs Goku* I missed you a lot.
Goku: Me too.
Cocoa: Oh and look, I became a lieutenant.
Goku: Ooooooh awesome.
Goku: How is everyone?
Cocoa: Fine. Goten became a captain, Jeff became LT's new lieutenant, LT kept doing his job and I became a lieutenant.
Goku: I see...well that's cool.
Cocoa: And what were you doing in this whole year?
Goku: Training, just in case Axel got released someday.
Cocoa: Oh...I noticed you look different since the last time I saw you.
Goku: It's the hair right?
Cocoa: Haha no, not only the hair. You look stronger too.
Goku: Ah, well thanks then.
Cocoa: You're welcome.
LT: Cocoa, you found the intruder!
Cocoa: Tell everyone to lift the intruder alarm.
Cocoa: This is no intruder, its Goku. He came back.
LT: Is that you Goku?!
Goku: ....Its totally the hair, but yeah it's me.
LT: ....Yeah it's the hair, but welcome back!
Goku: Well, at least someone didn't notice my hair first.
Jeff: I did, I just heard you talking to Captain LT.
Goku: ....Okay then.
Jeff: Welcome back.
LT: Before everyone finds us here, let's go to my house.
Everyone went to LT's house, where Goku started to tell them the stories of when he was off training.
