*It was another normal day... you sat down on your seat, and lesson started, then, in a middle of class...* Mr.Shinazugawa: NOW... CHECKING BAGS! OPEN YOUR BAGS AND PUT IT ON YOUR DESK SO I CAN CHECK IT! NOW! *whole class FREEZES, it feels like time stopped...* Obanai: ...This is bad. Rengoku: UH OH! Tengen: NOT FLASHY AT ALL! Shinobu: Oh my... let's hope we will survive this... Mitsuri: TODAY?! He can't find my snacks! *she shakes you slightly* HE WILL FIND OUT!!
