Summary
Ikuto Tsukiyomi is a fifteen-year-old Sagittarius with AB blood type and a birthday on December 1. He is a teenage boy contracted by Easter to locate the Embryo, though he secretly despises the organization. His true goal is to find the Embryo to grant his own wish and escape their control. He possesses the Dumpty Key, which pairs with Amu’s Humpty Lock, although it initially failed to fit into the keyhole. A skilled violinist like his father, Ikuto also has a Shugo Chara named Yoru. Physically, Ikuto is tall with dark blue hair and wears dark clothing. He sports a signature smirk that can signify either flirting or satisfaction with a statement. His Chara-Change grants him cat ears and a tail, altering his behavior to mimic a feline, while his Chara-Nari form is Black Lynx. His backstory is rooted in family tragedy. His father, a famous violinist, refused to abandon his art for Easter, the company his mother represented as heir. This refusal led to his disappearance, causing his mother severe distress and eventual hospitalization. Ikuto lived with Tadase’s family but faced harsh treatment from Tadase’s jealous mother. After running away and staying with Tsukasa for a time, he returned years later to Tadase’s home. There, he discovered Tadase’s dead dog, Betty, and a collapsed grandmother. Before being cursed out again, he stole Tadase’s Dumpty Key, which had been given to Tadase by his father when Ikuto’s father left. This event created a strained relationship between Ikuto and Tadase. As a child, Ikuto was quiet, shy, and protective, willing to take blame for others. This trait persists in his adolescence; he is ready to sacrifice himself for those he holds dear, enduring homelessness, capture by Easter, or being vilified as a villain. He cares deeply for Amu, likely harboring a crush on her, and reveals his true self only in her presence. He acts aloof, cold, and flirtatious, openly defying his Easter superiors. He enjoys teasing Amu and her reactions. In Shugo Chara! Doki, he remains at Easter to protect Utau, keeping his distance so she will have no further connection to the organization.
