Summary
Kotori Itsuka is a central heroine in the Date A Live series, serving as Shidou’s foster sister and a middle school student. At 14 years old, with a birthday on August 3 and a Leo zodiac sign, she stands 145 cm tall with AB blood type and measurements of 72-53-74. She enjoys lollipops, bath bombs, and dating sims, while avoiding anything horror-related. Her favorite quote is, "Now, let our date begin." Kotori serves as the head commander of Ratatosk, where she instructs Shidou on Spirits and Spacequakes, teaching him how to peacefully seal Spirits to prevent disasters. Her personality shifts based on the ribbon she wears. White ribbons trigger Imouto Mode, revealing her "weak self"—a delicate, dependent little sister who openly loves her brother. Black ribbons activate Commander Mode, showcasing her "strong self," a charismatic, cynical, and bossy tsundere leader capable of commanding the airship Fraxinus. Reine notes that the white-ribbon version is the one who can honestly express her feelings, suggesting the black-ribbon persona is merely a protective facade required by her duties.
