Umi tends to go slightly ballistic at times, and provides a bit of comic relief during her fights with Mokona. A fencing champion, she is quick-tempered and at first uncaring (though perhaps the best-suited for the task at hand), as well as the most reluctant of the three Magic Knights: she is under great pressure to attend a fencing contest and is unsure of the land of Cephiro. She is an only child of rich parents, the two of which dote on her mercilessly and for whom she has great affection. Umi Ryuuzaki ( 龍咲海 Ryūzaki Umi ?) is elegant with dark blue eyes and long, flowing blue hair. Voices: Hekiru Shiina (Japanese) Julie Maddalena (English TV Series), Tara Sands (English OVA) Hikaru decides that she would rather Cephiro not have to depend on one person's self-sacrifice, and uses her power as the Pillar to destroy the Pillar System and allow Cephiro to function on its own. It is apparent from the first moment the girls are told they will be Magic Knights that Hikaru is the most strong-willed and passionate of the group this leads to her eventually becoming the new Pillar at the end of the season. In the second season, when the need for a new Pillar of Cephiro is urgent, people from many different lands flock to Cephiro to become the Pillar. Hikaru claims to love everyone, and due to her innocent nature, probably loves everyone equally.

However, in the manga, Hikaru is only hinted at being romantically involved with Lantis, despite him hinting that he has strong feelings for her. In the second season, she falls in love with Lantis, and becomes friends with Eagle Vision of Autozam. She becomes best friends with Umi and Fuu in the first season. It's also mentioned that she's the most popular girl in her all-girls school by her classmates in both adaptations. When Ferio agrees, Umi cheers, as does Hikaru, though she still doesn't get it. Hikaru is very popular with fans, especially with boys, because of her sometimes childish behavior for example, in the manga, where Fuu is 'asking' Ferio to help them, Umi catches on to what she's doing, but Hikaru has no idea what's going on. She uses fire-based spells, such as Arrow of Fire (Honoo no Ya) and Crimson Lightning. In particular, she wants to save Cephiro in the first arc in order to return home to her dog, Hikari, her precious childhood friend. She is headstrong and determined, and in many ways very childish, but she is fiercely loyal to her friends. She helps her parents and her three older brothers (Masaru, Satoru and Kakeru) to run a school for Kendo. Hikaru Shidou ( 獅堂光 Shidō Hikaru ?) is an eighth-grader with bright red eyes and scarlet hair, who is small for her age and often teased for her boyishness.
