Emi Ibarazaki is one of the five potential girlfriends of Hisao Nakai in Katawa Shoujo. Emi has lost both of her legs below the knees and is on prosthetic legs, but that doesn't stop her being the best runner in the track team. She lost not just her legs in a car crash, but also her father. Her father was a runner and she was inspired to become a runner after his death, even though she's on prosthetic legs. After the accident, she underwent extensive rehabilitation including fully relearning how to walk. The process was overseen by the Nurse, which explains why the two have such a friendly relationship.
She is best friends with Rin Tezuka, becoming friends after the housing department decided the two would "compliment each other", meaning that the two of them together will have a full set of limbs. Emi and Rin are very supportive of each other, despite that Emi thinks Rin should do more sports, while Rin just thinks sports is "horsing around". Rin will attend Emi's track meets, and Emi will help Rin with her mural. Emi is relatively close with the track team captain, Miki Miura, as well as the other teammates.
