>Makoto: "Really..!?"

>Sayaka: "Just joking! You're so gullible sometimes, Naegi."

Byakuya and Yasuhiro were arguing like an old married couple.

>Yashiro: “But dude... What if the water got some feels or somethin’... What if the water feels?”

Aoi and Sakura were talking

Celestia was ordering Hifumi around

>Celestia: "The tea is cold, and the sugar is warm! How did you mess up tea!??"

>Hifumi: “EEEEEE!!!”

Chihiro, Kiyotaka, and Mondo were hanging out

Toko was stalking Byakuya while Leon was practicing music, which he was failing at.

>Leon: “I bet I can play crazy train!”

Junko was insulting Mukuro and Mukuro was just silent, taking in each insult as they walked through the hallways.

Kyoko was watching everybody, observing everything she could.
