Aki Matsui was a student in 9th Grade Class 3 in 1998. She was good friends with Kyouko Kaneki and later would become one of the "Deaths of August".


Aki was a girl with a pale complexion, of average height and a delicate face, she had dark brown hair which reached chin length, and the one she combed with bangs between her forehead, and her eyes were brown Dark.

As a student, she was only seen wearing the standard female school uniform.


She used to be a very shy and reserved girl, but calm and humble, which was almost always seen in the company of her best friend Kyouko Kaneki. It can be shown that Aki is prone to moments of anguish and anxiety, so when this happens Kyouko takes it upon herself to comfort her friend and ensure her peace of mind. It is also shown that she is passionate about practicing sports, and more in the company of her friend.


Aki did not have much appearance in general like several of her classmates, so on each occasion she was seen in the company of her best friend, Kyouko. The two's first chronological appearance is in "The Other," spending the day at the same amusement park as Mei and her sister.

Aki was among the students who went on the class trip to the shrine, where she shared a room with Kyouko. In "Makeup" she and Kyouko heard Takako's broadcast, but unlike most of her peers, she did not actively seek Mei out, instead preferring to flee the now burning inn with Kyouko.

At some point in "Stand By Oneself", Aki suffered a breakdown, as when she and Kyouko are shown, Kyouko can be seen protectively wrapping her arms around Aki, apparently in an attempt to calm her. Unfortunately, the two encountered Tomohiko Kazami, who had come to the same conclusion as Takako, albeit with a much more macabre and ruthless approach. Tomohiko stabbed Kyouko in the back with a knife she had stolen from the inn's kitchen, before attacking Aki, the knife was still dripping with her friend's blood. Horrified for her life, Aki fled and encountered Kouichi. Sobbing and scared, Aki begged Kouichi to protect her, but before she could react, Tomohiko threw her knife at the base of her neck. Aki died in Kouichi's arms, an expression of agony on her face.

Removing the knife from the still warm body of his classmate, Tomohiko nonchalantly asked Kouichi if he "remembered this girl". Furious, Kouichi replied yes. Undaunted and realizing that neither of them was the extra, after this he prepared to attack Kouchi, leaving the corpse of the quiet girl in a pool of her own blood.
