We last left off with the four in Ben's house as he asked the question.

Ben: Are you guys... from an alternative universe?

Then time stops, with only Y/n able to move, looking confused.

Y/n: Huh? (Goes to Ben) Hello? Yo, Aibou, you seeing this? (He turns around to see Iori and the Digimon frozen too) Aibou? Impmon? Commandramon? (Snaps his fingers) Hey! Is this a joke or something? Or maybe Hundred?!

A portal opens up on the ground where Y/n is standing. He looks down, then looks at the reader and pulls out a sign that says "Uh Oh" as he screams and falls into the portal.

Y/N fell down on the ground as two portals appeared and two people fell down three of them groaned in pain and they were confuse.

Y/n's: ow....that hurt...

????: Ugh... Is this another world for me to travel?.

???: Where the hell am I??! Am I fuc- (Scott Pilgrim bleep sound) dead again?! Aw, come on, I just wanted to sleep and this happens?!.

????: No, we aren't dead. We in the white void for some reason and the portal bring us here for some reason.

Decade: Honoka Kaguya Quartz? You know her?.

Kuuga: What do you guys mean? You mean Houou Kaguya Quartz? I've never met the guy, but I've seen the special and the episode.

Decade: Mine is a female version of Legend but different is her name was Honoka Kaguya Quartz.

Dark Decade: For me... I guess there's a female version too, but her name was Hotaru Kaguya Quartz, and we were childhood friends that made a promise... if we got old and still single, we'd dated each other.

Decade: I see...

Kuuga: I wonder if I'm going to meet my Genderbend rider. Well, if the author thinks it's a good idea.

Decade: Who are you talking to?.

Decade: As much we love to talking, we need to return to our world.

Kuuga: Awww....but you're right.

Decade summons Aurora Curtain.

Decade: Lucky I can access Aurora curtain, we better get there.

Dark Decade: Woah, I can do that too! But I think I'm still weak after fighting my sensei.

Decade: I see... Guess we gonna depart away.

Dark Decade: Yeah....but it was good to meet you guys.

Kuuga: Same here! I hope we meet again!.

Kuuga goes to Dark Decade, reaches his hands, and then they do the Fourze handshake.

Dark Decade: What was that handshake?.

Y/n: That was the handshake of friendship! That means we're friends!.

Dark Decade: Whoa! Thank you!.

Kuuga: You're welcome! (does the Kuuga thumbs up).
