The cashier for the Card Capital shop and another Vanguard player. She is not as "enthusiastic" as some players are when it comes to the game, but she enjoys it all the same. Normally, Misaki is calm and quiet, but she can become quite stern when she wants to, scaring almost everybody. She is the first person to beat Aichi in a game of Vanguard using her Oracle Think Tank deck that her uncle and Card Capital's manager, Shin Nitta, made for her. It is revealed later she lost both parents when she was little and hasn't played Vanguard ever since until recently. After the events of episode 25, Misaki starts wearing around her neck the key to a box that contained a deck that her deceased parents made for her when she was a child. She is also shown to have a great memory to the point that she can memorize anything after seeing it only once. Misaki's strategy involves using her perfect memory and cards' skills to learn what cards are at the top of her deck and in the opponent's hand so that she can confidently make her moves. Her aces are CEO Amaterasu and Goddess Of The Full Moon, Tsukuyomi. In season 2, Misaki eventually changes her deck to the Witch Oracle Think Tank theme, and her new key card is Scarlet Witch, CoCo.
