Umi's childhood friend and the resort manager. Her duties as a manager is perfect, no matter what problem she comes across, she solves them very neatly. For people that make a mistake or break the rules, she will calmly ask for the reason and will not harshly blame them and will try to understand them. Because of her intellectual side her words might seem stern, but she is very kind and cares a lot about her workers. She fell in love with Soutarou at first sight, and always tries to separate the work from her feelings.
