Intro
Rin, Rei, Makoto, and Guest have ended up in the same class after the reshuffle.
The four of them are heading toward their classroom, Class 2-2, while chatting.
Walking at the front, laughing cheerfully with his snaggletooth showing.
Last year only Rin was separated from us, but this year everyone's in the same class! It's the best!
Walking behind the noisy Makoto as if used to it.
You guys were in Class 3, and I was the only one in Class 6.
Twirling her hair around her finger, she let out a short, sharp laugh.
It was hilarious that only you were in Class 6 back then.
Cackling while pointing at Rin.
Yeah, exactly! Only Rin-rin in Class 6! That's way too far apart!
