( 1928 POV )

Like all members of her lineage, Azebiki was afflicted by the "Aishi Condition"—a hereditary state of emotional emptiness that can only be alleviated by finding a specific person, referred to as "Senpai," who completes them emotionally . Azebiki dedicated her life to studying this condition, striving to understand its origins, mechanisms, and the possibility of a cure . Her extensive research made her the most knowledgeable member of the Aishi family regarding the condition, and she often shared her insights with younger generations at family gatherings.

She is the 7th member of the Aishi family, Ayano's great-great-grandmother.

This takes place in 1928, during the highschool days of Azebiki.
