Another Isekai Story : Lazy Life is The Best in Another World

Prologue

"Congrats....all of you are dead"

That is some ridiculous words said by some stupid looking old man.
I don't know how i've gotten here, but what i do know is this place is huge.
If i have to compare this place, i think the most suitable place is the great cathedral from medieval europe.
That's strange, because last time i remember, i was in the bus with my high school classmates on our way to visit some crappy food factory for our school trip.
Well, good thing is, i think that stupid school trip is canceled now.
Bad news is now we are trapped here with some crazy odd looking old man, and when i look around, i don't see any windows or doors.

"What do mean by that?! What is this all about?! A prank?! Where are we? Who are you? How can we all end up here? I demand an explanation!!"

Wow, that's fierce. She really up to her nickname, 'Iron Lady', that is our homeroom teacher. I can see that old man who stand in front of the altar start strembling after bombarded with questions without any chance to answer that.

"Hey teach, i don't think he can answer your question if you don't give him a chance to do so."

Nice, class rep. You are as dependable as always. I also want an explanation, and i don't think anyone in this room except that old man can explain whats going on here.

"Okay, gramps. I think you need to explain a lot of things here. Now, who are you and where are we? How can we end up here?" (Class rep)

"Well, first, i think i need to introduce myself. I'm what you call a God. Truth to be told, i'm more like a manager of the worlds. God is a concept that is entirely different from me, but for the sake of this explanation, lets just say i'm a being thats closer to the God that you know."

Silence.....

Great...that goes my hope to get an explanation from this crazy old man. I think i need to start searching for exit. Then, he continues..

"All of you had died in your world. That is some unforeseen and unplanned accident, and for that i apologize because that is a mistake on my part. I accidentally drop a Sunray Beam to your bus when i tried to practice my Light magic for some apocalyptic monster from earth 30. I didn't think there would be any vehicle on that secluded mountain road."

"Stop this nonsense! Don't make me come over there and hit your head, you some sick lunatic." (Iron lady)

Hey hey, that's not nice. I agree with sick lunatic part, but i don't think he should get some smack in the head. He is crazy, you kick his ass and then he will become some crazy angry sick lunatic. Crary is already bad enough, and i'm sure we don't need an angry part.

"I know what all of you thinking right now, so here i'll show you the scene where you all dead in the real world"

Suddenly the air in front of us vibrates, the space become distorted and then forms some kind of screen. The image in that screen is so clear and vivid, and in that scene, i can see our bus.

"What..."
"Hey, that's our bus"
"Where did that screen come from?"
"Wait...no way....there was really a ray beam. Is this some kind of photoshop?"
"That is...AAAAAH!!"

Next scene that is projected is so horrible, some of us begin crying, some are fainted, and some are puking. There is no mistake that is our school bus and suddenly a sunray beam struck our bus, making a loud sound and after that..........Hell.
