That afternoon was calm as usual, Rin and Yuki walked towards their private dormitory. As they were about to enter the cafeteria area, they heard a sound in the kitchen

Yuki: is anyone there?

Rin just shrugged his shoulders in response. The sound got louder, as the two of them approached, there was an explosion from inside the kitchen

Rin: damn! What happened!?

when the smoke begins to subside, one of the little devil chefs named Ukobach is seen standing on the table tidying up pans, spoons, plates and other tools
