Description

Umi is a rich pretty girl who does not hesitate to state her opinion. Although she seems spoiled on the outside, she cares deeply for her friends - Umi was the one who made the first step that forged the friendship between the three girls. It was raining and Hikaru lent her umbrella to another student, lying that she had another umbrella for herself. Fuu was watching from afar, but did not have the courage make conversation with Hikaru. Umi then suggests the three of them head home together since they live in the same direction.

After the invasion of Cefiro begins, Clef leads Umi and Fuu away from the battlefield while Hikaru fights with Lexus. After Fuu makes up her mind to fight as well, Umi still tries to run away. In the end, Ascot forces her to live up to her fears of being the only left and awakens Mashin Seresu.
