Nurse Tomo, whose full name is Tomoko, is a supporting character in the anime Angel Heart and is commonly addressed as Tomo-chan. She works as a nurse for Doc, the doctor connected to the series' main cast, and is a recurring presence in the clinic scenes of the anime. She began working for Doc soon after Kaori Makimura left the clinic to work alongside Ryo Saeba, a departure that followed the murder of Kaori's brother. In her role, Tomo assists Doc with his medical practice and is regularly subjected to Ryo's constant romantic advances, which she endures while carrying out her duties. Her connection to the main characters is defined largely through her workplace: she serves directly under Doc, and her interactions with Ryo are shaped by his persistent flirtation. As a minor supporting character, she does not have a major storyline of her own, and the series does not develop her individual personality, personal motivations, or specialized abilities in depth. Her place in the story is mainly tied to the everyday life of the clinic rather than the central plot.
