A senior at Third High. Her family and Airi’s family are close, and since they grew up together, they understand each other well. As her family name suggests, her family is part of the Water Elements lineage, and her specialty is water magic. However, she lost against Mari in the Battle Board competition, and feels intimidated by Mayumi and the other seniors at First High, who are known as the most powerful team of their generation. Though she doesn’t possess any superior magic skills, she is kind and compassionate, and knows how to comfort players when they lose in competitions. Airi and the other younger students adore her.
