(Irimi is a woman with long, dark hair that has long, parted locks in the front. Irimi dresses fairly casually. At first glance, she seems to be a rather solemn and taciturn woman. After the timeskip, she has her hair shorter due to cutting it.

In the past, Irimi's hair was considerably shorter.

Her ghoul mask resembles a Doberman's face.)

*Irimi is a quiet and reserved young woman who normally keeps to herself. In subtle moments, she can be quite annoyed and speak out her honest thoughts however. She has also been shown to be especially kind towards Touka Kirishima and Hinami Fueguchi. Like Enji Koma, Irimi has been with Yoshimura long before they were employees at Anteiku and is quite loyal to the manager. When she was about to die, she was willing to accept and embrace her death, described by Renji Yomo, it was punishment for her past sins.[1]

In the past, Irimi was a very murderous ghoul who possessed a more savage and cruel disposition, with some of her actions including the brutal killing of the entire squad of Ghoul Investigators sent to kill Irimi and her gang, the Black Dobers. She then proceeded to sadistically leave a single survivor after brutally scarring him.*

A decade prior to the series, Irimi was the leader of a notorious ghoul gang of the 20th ward recognizable for wearing black Doberman-like masks. A rival of the Apes and their leader, the Devil Ape, the two gangs clashed often. She was involved in killing many associates of Chuu Hachikawa. She may have been the ghoul who disfigured Hachikawa's face during this time as well. After meeting Yoshimura[2], she drifted from her violent past and became a waitress at the café, Anteiku. After joining Anteiku she was immediately put to work as a barista, to the disbelief and incredulity of Koma who had spent months only cleaning before Yoshimura let him brew coffee (and was relegated back to cleaning when Irimi took over the counter). She became popular with the male customers, and also became friends with a female customer named Tsubasa. It was also revealed that she had an unnamed boyfriend around this time. During a conversation with Tsubasa, the other woman expressed admiration for Koma and how hard he worked. This led to Irimi feeling jealous on how easily Koma was able to interact with humans, and she vowed to work harder at this.[3] A few years after she began working at Anteiku, Eto Yoshimura stood outside of the café and witnessed her and Koma having an argument about which made better coffee. After the shop was closed later that evening, she bid the manager goodnight.[4] Also, around this time Irimi and Yoshimura are seen observing Renji Yomo and his comrades as they are about to battle Kishou Arima in the 4th ward. For some reason, they are focusing on Yomo specifically and when Irimi asks Yoshimura how they should proceed, the latter states he doesn't know.[5] Years later, Touka asked Irimi what the meaning of "Anteiku" was. Irimi smiled and stated she should ask Yoshimura herself sometime, noting that the meaning itself was beautiful
