Field day

Today is now Field Day, hopefully the last day where everyone can all go home, everyone was together and were ready to win the games. Emilia was standing in front of everyone.

Emilia: Let's do our best today!

Everyone except Zero who nod: Yeah!

Everyone was chatting in the courtyard, that's when...

???: I-I found you!

Everyone turned their attention to see a girl.

Kazuma: Oh! Yunyun!

Yunyun: Megumin! Today, we're having our duel!

Subaru: What's her deal? Friend of yours?

Megumin: I never seen her before in my life. She's probably looking for a different Megumin.

Yunyun: Hey! Hold on! We're rivals for life!

Megumin: So. what do you want?

Yunyun: We, class 3, will win the field day today!

Emiya came in and sees Yunyun.

Emiya: Yo! Yunyun!

She saw Emiya waving at her and she blushes and spoke up.

Yunyun: *blushing* O-Oh! (Y/N)! I didnt expect you to be here

Emiya: Same goes to you

Then Megumin cleared her throat and spoke up.

Megumin: Anyways, Yunyun, do you even know what a field day is?

Yunyun: You and your friends in the class work together to complete...

Megumin: Do you have any friends to work together with?

Yunyun: Of course I do! Right now, my friends are in my class and are sending me to buy some Yakisoba pan!

Kazuma: Be quiet! You're just making us sad by just listening!

Emiya: Wait, you said class 3 right?

Yunyun: Yes.

Emiya: *Sighs* Do you even realize that class 3 that no one is in there? Shouldn't you be in class 1 with the others?

Yunyun blushes in embarrassment by your question.

Felt: Hey, big bro!

Subaru: Oh, Felt! Geh and Julius!

Zero: Yo...

Felt: Sorry bro, but class 1 will win today!

Julius: "Geh"? That's some greeting, Subaaru, let's have a fair fight like true knights should.

Kazuma: Who the hell is this dude? I don't like him.

Subaru: Yeah, I get it.

Meanwhile with Ainz and Gilgamesh as theyre with the Pleiades and they were all kneeling to him.

Yuri: I'm sorry, Lord Gilgamesh, Lord Ainz...I had no idea we'd end up on opposite sides...

Gilgamesj: Don't let it trouble you. Yes, you combat maids, the Pleides exist to be our shield...but this is another world now that we are in different classes, there's no need to hold back. I've no interest in this farce of a battle, but let us do our best as rival teams.

Yuri: Thank you for your kind words.

Ainz: Well this is basically like the team fights we did in our guilds.

Gilgamesh: Indeed Ainz.

Yuri: There is one matter for concern. There's someone in our class you should be concerned with...
