Azusa

A handsome woman past her youth, Azusa wears her pale hair pulled back into a ponytail with strands hanging along each side of her face. Blindness keeps her eyes shut, and a small mole sits on the skin beneath her left one. Her usual outfit is a long-sleeved top over a pale skirt, worn with a black apron while she serves customers. Once surgery removes her tumor, her reopened eyes turn out to be dark, much like Hotaru's.

When her thoughts drift toward killing, a distinct bloodlust rises in her look, a trait Korosensei found reminiscent of Nagisa Shiota.

By nature Azusa is warm and unassuming. After the tumor set in, however, she quietly fixed on a single aim: securing Hotaru's survival and livelihood. That resolve hardened into a carefully worked-out plan to end her own life together with Korosensei's, so that the bounty on him would pass to her daughter. When Korosensei foiled the attempt and, along the way, treated the tumor itself, she promised instead to live life to the fullest at Hotaru's side.

As Hotaru's mother, Azusa loves her fiercely. Her brain tumor left her terrified that her death would strand the girl in poverty, and rather than accept that outcome she engineered a scheme to die alongside Korosensei and hand Hotaru the reward money. The plan came apart when Korosensei rescued her and removed the tumor, making her, in fact, the very first person he mended through the 'polishing' he offered in exchange for attempts on his life.
