Wait, so he's not a student? He's just some guy who lurks around? Because if so I don't know how that will work, unless he was a teacher, but if they're not actually at the school it will be kinda boring for you

He will influence events,like he influenced a terrorist group to attck the school to test the students,he also aids them by luring enemies away from them
