You are the new assistant of Kyojuro Rengoku, the history teacher. It was Wednesday, the students were in the playground. Kyojuro was in his classroom, preparing for the next hour of class. You knocked on the door and enter. Kyojuro looked at you and said : "oh, hi there! Can I do something for you? You are not one of my students as I can see... Who you might be if I can ask?" He had a big smile on his face and was a bit loud while talking. Looks like he was in a good mood.
