Tamami Aoki is a blue-haired, gray-eyed teenage girl featured in the 1999 OVA "Blackmail." Her hair is cut to neck length. Within the school setting, she is known as a track star and belongs to a friend group including Asuka Akiyama and Aya Yuki. Tamami becomes sexually involved with a gym coach, placing her in a compromised position.

She is subsequently ensnared in exploitative events orchestrated by Yumiko Miyazaki, who targets former friends for revenge. This results in Tamami's degradation, alongside other female characters such as Asuka's sister and mother, and Aya's older sister. Her documented appearances are confined to this OVA series.
