I'm rewriting some things as it sucks. I don't know where to put in the plot and here it is

Chapter 1: Light God's Oracle

My knights... You all are to guard this girl. She will be the Oracle of the Light God. Feisty, rude but a nice girl. Treat her well. After you all gather together, she will appear. Help her adjust to your life.

All the 12 Holy Knights and the Pope woke up abruptly. Not believing that they just saw their Light God. They all woke up to prepare and hold a meeting, asking the others whether they heard the Light God or not. They all mostly argued to each other about different theories about the new Oracle and prepared for a banquet, approved by the Pope and the reluctant 'Pig' King who was 'persuaded'. The Hell Knight didn't bother coming even if his curiosity was nagging at him.

Then, they gathered in the church and surrounded where the symbol of the Light God, which was etched into the floor. They all lifted up their hands and used some holy magic to insert into the symbol. It lighted up and a bright momentarily blinded them.

A girl kneeling on the floor with odd clothes that seems a bit inappropriate yet at the same time, kind of modest. She opened her eyes and-

"WHAT THE FUCK?!"

Where am I? I've just been walking home from a nearby convenient store, buying some snacks and a milk tea bottle, when suddenly a light engulfed me. I'm just here, floating up here.

"Hera Crow" I heard, I spun around to see an almost Albus-too-many-middle-name-Dumbledore as he had a long beard, yet a hippe version as he has a crown of flowers on his head, using a fancy pansy gown.

"Who're you?" I asked.

"I am the Light God of another world, other than your own, and I need your help as I could not interfere with human's lives." The Dumbledore look-alike said. I looked at him with disbelieve, as if he is a crack-pot.

"Then how do you rule the theory about the light engulfing you and nobody is in here except us?" The Light God or whatever, said. Mildly annoyed but not pissed.

"I'm also a crack-pot? And are you reading my mind?" I asked

"No and yes. Now, continuing on, the world is a lot different than yours. Their technologies are still back as they use carriages and horses to move around. Danger will be approaching and I need you to give out the word. I only can speak out every century and have been accumulating it, causing almost nobody except for a few, to even properly consider me as a real god" He said.

Before I can get to say a word, he continued on even quicker

"Well, I will gather all your belongings, and transfer everything there, convert your money and give you knowledge about what they should all know in 3 days. The rest is up to you. Bye~" He said and the world turned black. No, my eyes are still opened. But a bright light appeared once more and I soon felt the floor. I snapped open my eyes to see a bunch of weird, but good looking guys. The only thing I could say is

"WHAT THE FUCK!"

END!

And so, I am thinking that all of the Knights are at least in their 20s
