Tadase Hotori (辺里唯世 Hotori Tadase) is one of the main heroes of Shugo Chara!. He is the leader of the Guardians, also known for the "King's Chair".
He is voiced by Reiko Takagi.
Like Amu, he is actually a shy person and is not good at public speaking; instead, he Character Changes with his Guardian Character, Kiseki. Although he is popular with the girls, when a girl confesses their love to Tadase, he will have Kiseki reject her.
Whenever he hears the word "ouji" ("prince"), or anything resembling the word "ouji", he Character Changes into an egotistical king who seeks world domination.
Amu develops a crush on Tadase soon after she transfers into the school. His love interest is Amulet Heart, Amu's Character Transformation with Ran, but it later becomes Amu herself. In episode 39, Kiseki's egg turns into an X Egg because Tadase lost his self-esteem by not being able to find the Embryo. With the help of Amulet Heart, Tadase turns back to normal. 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. Amu and Tadase reconcile soon after, though. Later on, he agrees to help Amu save Ikuto from Easter. Tadase confesses his love for Amu in chapter 28 (episode 74 in the anime) behind Amu's house while Ikuto was hiding in Amu's closet. Ikuto overheard and made fun of Tadase, only to protect him, which he knew nothing about. When Tadase was facing against Ikuto in chapter 35, his staff becomes a sword called Royal Sword in episode 99. Tadase ventures into the Eggs' Cradle with Amu, but subsequently gets separated from Amu due to a meteor shower. The future Tadase, who looks like Tsukasa helps Amu and reveals himself to be Tadase. In episode 127 of the anime, he kisses Amu on the cheek and tells her that he'll always be by her side.
- He is same year as Amu and serves as King's Chair of the Guardians.
