I'm the Class Representative?

Did she saw me with Momo, Azure and Tia?, I said to her that I helped them, " even they are a thief huh?", she also saw that?, I just can't stand there and do nothing, Momo will be punished by cutting her ears, that's far to cruel for me to take in." and even take them to a restaurant and a inn huh?", Just how much do you know?!, she explained and she's been following me all day yesterday, her explanation was, Elise and I go to the same dorm so she's following me, actually more like stalking me!. After that we entered out classroom and I see Taruko, he's back and this is a opportunity to ask him a question about that Berserk magic he used, and then Selania entered the classroom, " before we start, Marco Higurashi!", She called me out and " you will be the class representative", huh?, Why me?, I asked her about the details, it appears that Bella didn't want to be the class representative, she's just after the right to challenge anyone. Well mostly all of us want to have that, but what will the class representative do?. " you will be leading the class seven, for short you are the leader of this class. Who would have thought that being a class representative can be exiting.
