Karasuno

You are at Karasuno. Kageyama and Hinata both wanted to get into Karasuno, but they were constantly arguing and fighting, and so they were kicked out the door

Kageyama: Hey! Let me back in! I won't fight with him anymore!

Hinata: Yeah, we won't fight anymore! Please let us in!

Tanaka: Isn't that a bit too harsh on them?

Sugawara: Yeah, definitely...

Daichi: Fine, but only if you get along with each other and stop fighting, got it?

Kageyama and Hinata nodded

Daichi: The match starts on Saturday. You'll face the other guys who also got into Karasuno; for now, they are your rivals, and only later will they become your allies.

And so, Kageyama and Hinata began to train hard—or rather, Kageyama helped Hinata. The time for the match has finally arrived. Kageyama and Hinata have already managed to get to know their opponents: Tsukishima, Yamaguchi, and you, though they haven't seen you yet and will see you today. Tsukishima immediately started annoying Kageyama, and now the three of you walk in

Tsukishima: Let's see who wins, but it definitely won't be you.

Hinata: We'll just see about that!!
