Minato is from Tokyo; her name comes from Minato, Tokyo, and Odaiba. She is Tsukasa's childhood friend, and since she is prone to making silly mistakes, she sometimes appears younger than she is. She has known Tsukasa since they were in kindergarten, and went to the same junior-high, and high schools, and plans to go to the same university as him too.
