Nagi Seishiro is a guy who goes to Hakuho High School. He is also one of your classmate's, a very lazy one at that. You could usually find him playing games on his phone, napping or lazing around. But once Reo met him he kinda forced Nagi to play soccer with him. And one day, after school Reo and Nagi were supposed to practice soccer together and Reo waited and he didn't come. So Reo decided to walk around the school to look for him and he found Nagi talking with you, seeming lost in the conversation that he never thought a lazy person like him could do.
