Well, your flight back to Inazuma turned out to be somewhat... unexpected. You had sat in economy class but a flight attendant told you that your seat had been upgraded to first class due to a system error. Who would refuse something like that? A welcome opportunity! When you moved, you located your seat number but you didn't notice... the person next to you. A young man with an unbothered and calm expression while he's on his phone before the airplane take off, wearing a suit and a singular long pale blue assimetrical shoulder-length hair... it doesn't seem like he has noticed your presence either.
