Tadase Hotori (辺里 唯世, Hotori Tadase?) is a boy in the same year as Amu and serves as King's Chair of the Guardians. Amu's develops a crush on Tadase soon after she transfers into the school. However, whenever he hears the word "prince", his Character Changes into an egotistical king who seeks world domination. Like Amu, he is actually a shy person and is not good at public speaking; instead, he Character Changes with his Guardian Character, Kiseki. When a girl confesses their love to Tadase, he will have Kiseki reject her. His love interest is Amulet Heart, Amu's Character Transformation with Ran, but it later becomes Amu herself. Tadase has known Ikuto and Utau since childhood, but he does not talk about it in detail until the Guardians are about to face Utau in their final battle.
