Yuuichirou Kumada

Yuuichirou Kumada was an apprentice at Hikawa Jinja who appeared only in the anime. At first, he seemed inept and lazy, but it soom became evident that he was a hard worker who was very dedicated to the shrine, Rei, and Rei's grandfather. He made his first appearance in episode 030, sleeping on the steps in front of Hikawa Jinja. When he woke up, he saw Rei Hino and immediately fell in love with her. Due to his love, he begged Rei's grandfather to allow him to become an apprentice. Later, Rei's grandfather began an intensive training program for Yuuichirou, telling him that becoming a shinto priest is tough work, and you can't do it with a soft attitude. Although the training was very difficult and physically exhausting (Yuuichirou seems to fall and hurt himself quite often), he was very determined to continue working hard.

In episode 038, Yuuichirou revealed that he was actually from a very wealthy family. Usagi and her friends wanted to visit the Moonlight Course ski resort, and Yuuichirou offered to let them stay at his parents' home near the resort, since his parents were away at their vacation home in Switzerland. Rei asked why someone from such a rich family would choose to work at the shrine, and he told her that he wanted to better himself. During this episode, Yuuichirou attempted to protect Rei from a youma's attack, only to be knocked unconscious in the process. Although Rei later called him a "useless idiot," she did kiss him on the cheek while he was unconscious.

In episode 99, Yuuichirou (believing that Haruka is male) was hurt when he began to believe that Rei and Haruka were dating. Later, he saw Haruka with Michiru, and was angry because he felt that Haruka was cheating on Rei. He challenged Haruka to a duel, but she wasn't interested in the fight. Rei overheard the argument, and tried to intervene, but Yuuichirou misunderstood her and continued believing that she was with Haruka. He decided to leave Tokyo, and the Inner Senshi persuaded Rei to go after him. At the train station, Kaolinite appeared and extracted his Pure Heart Crystal, knocking him unconscious. After quite a battle (of which he was unaware), Rei took him home and took care of him.

Yuuichirou's seiyuu was Bin Shimada.
