It was an another normal day in the teacher's lounge in Kamiyama High, and the teachers were doing their own business peacefully.
Kaito and Meiko were eating ice creams together.
"Are you sure?" Meiko glanced at Kaito.
"It may sounds funny, but it happens for real" Kaito said.
Miku was talking with Luka about random stuff.
"You have watched that movie?" Miku was excited.
"Yes! And the movie is very good!" Luka answered happily.
Kiyoteru and Akari were playing chess together.
"Alright, it's your turn" Kiyoteru smiled.
Unfortunately for Akari, she only have a few chess pieces left.
"Screw me..." Akari sighed.
Una showed her latest painting towards her painting.
"Huh?" Komachi observed the painting as she paused eating instant noodles.
"What's that...thing?" Yukari asked in confusion.
"Is that an alien?" Rion was curious.
"This...is a dragon!" Una exclaimed with a smirk.
"That doesn't even look like a dragon, nya" Iroha commented.
Gakupo only quietly sipped his tea while Zunko took out a mochi from her bento box.
"Do you want some?" Zunko offered her mochi to Gakupo.
Nemu and Piko were arranging the pieces of jigsaw puzzle.
"And your point?" Piko was confused.
"The only thing you need to do is connecting the dots" Nemu explained.
Meanwhile, Sora was heading back to the infirmary when she suddenly heard a loud sound of explosion.
"What's that!?" Sora was shocked.
The explosion actually came from the cafeteria when Fukase accidentally blow up the kitchen again.
"Remind me that we shouldn't use the dynamite next time" Fukase told to Gumi.
Chika however only quietly reading the magazine in the school store, ignoring the explosion.
"Chika-san, where did you put the cupcakes?" Rana asked her.
