Ikuto Tsukiyomi

Ikuto Tsukiyomi is a violinist and bearer of the cat-like Guardian Character Yoru in Shugo Chara! Controlled by Easter Company through his family circumstances, he repeatedly crosses paths with Amu Hinamori while searching for the Embryo.

Teasing, secretive, and outwardly detached, Ikuto hides loneliness and a strong desire for freedom. He cares for his sister Utau and gradually trusts Amu despite being ordered to oppose her.
