Takako Ayasaki is a student at Kayou Private Academy and a classmate of Nana. Her blonde hair, a trait from her great-grandmother's Caucasian ancestry, features spiky bangs, wavy sidehair, and an intake. She possesses brown eyes and a slim, pale physique, standing 152 cm tall, weighing 40 kg, with measurements of 78-53-76 cm. She typically wears her school uniform accessorized with a headband, a scarf, and pantyhose. Takako exhibits a carefree and strange personality, often marked by repetitive speech. Her social standing is that of an ojousama, indicating a privileged background. She developed romantic feelings for Shuugo after meeting him during his time as a police officer, maintaining pure, unwavering feelings for him. Her background centers on this enduring, unrequited affection rather than significant personal evolution. Across the visual novel's releases, her narrative role shifts: she is a main character in the "REBIRTH FHD SIZE EDITION" but appears only as a side character in all other versions. Her story arc or development is not elaborated upon in spin-offs, OVAs, or adaptations.
