Ryou Fukiishi (吹石 稜, Fukiishi Ryō?) is a truck driver that Taisuke encounters after just leaving his home in search of his friends. She leaves Yuta with her phone number so he can call her if he gets lonely as she bears a striking resemblance to Yuta's late mother. She has a husband and a daughter that she adores. She visits Taisuke's sister every year on his birthday.
