A man in a black coat on his golden throat seat watching each world stories. It was out of boredom since there wasn't much to do because everything was peaceful as he tries to find some hobby. A thought occurred to him as he rubbed his chin underneath the black hood with his right hand.

Author: Hmmm....I got an idea. It's so crazy that MIGHT just work. Hehehe.

He rubs his hands together of excitement. Snap his fingers creating a huge red and gold theater and dark sky ceiling with stars like dots.

Author: Okay. Now there's one more thing I need to do.

He claps a few times as people from various fictional characters from their own respective worlds appear unexpectedly and confuse of just happened. Over at Team Isekai Quartet.

Suddenly everyone heard a man's voice through from the speakers.

Author: Ahem. Testing one! Two! Three! Can everyone hear me?

They nodded.

Author: Good. You're all probably wondering why I brought you here. Huh?

Kazuma: No shit!

Author: Ayo. Well isn't Kazu Trash himself. Steal any panties lately that'll make more women hate you?

Kazuma is shocked he knows what he does sometimes whether it be an accident or get back at people.

Emilia raised her hand.

Author: Yes. The silver hair girl behind the Lolimancer.

Subaru: Hey!

Emilia: Umm...who are you?

Author: I have been known by many names. Lord Drakkon, Ohma Zi-O, Mao, God, mountain lion slayer, the Azure and so on. But you can call me..... Tiffany.

Emilia: Really?

Author: Nah. I'm just messing with you. Although I am basically God.

Tanya rolls her eyes calling himself God.

Ainz: What is it you want with us?

Author: Well skeleton, man. I brought you all here for the reaction of one of the worlds/story.

Everyone: Reaction?

Rimuru: Seriously!? That's why you brought us here!?

Everyone began bicthing and wanted to go back home except the author snap his fingers to get their attention.

Author: Hey! Hey! Hey! Don't make me pull a Thanos Snap on you guys! Anyway... don't worry I'll send you back at the exact moment and time where you'd all at. There will be breaks here and there and sleep time. Also if you expect to use magic or any superpowers. Guess what y'all that I ain't happening because I put restrictions on ya so you won't try do something especially picking a fight with one another. Plus during the break everyone will get to know each other. Look I promise to send you all back later on. Okay.

Neptune: Can we get snacks then? I want pudding.

Author: Ah. Classic Nep. You remind me exactly like my wife. She's a pudding connoisseur. 'Literally my wife is Neptune, but way more further than beyond that Neptune in front of me.'. Snacks and drinks are at the lobby. Help yourselves out.

Everyone sat down with food, drinks and some comfort items like pillows and blankets.

Author: Is everyone good?

Everyone: Yeah.

Author: Good. Now then shall we begin. 'I hope they don't annoy me'.
