Aguri is shown to be cheerful, clear-minded, and passionate when it comes to teaching. As a teacher of Class 3-E she is quite intelligent, being able to teach any subject in spite of chemistry being her first preference. She is also hard-working, having been essentially forced to work as a lab assistant to her abusive fiancé during night hours. Aguri is also very perceptive. When the original God of Death wondered why his apprentice betrayed him, Aguri replied that his apprentice might have wanted his master to "see him", a perception later proved to be tragically prophetic. She is known for her odd sense of fashion which often leaves others dumbfounded. Despite that she is remembered very highly by those who knew her and continues to make an impact in their lives.

Assassination Classroom
When a mysterious creature chops the moon down to a permanent crescent, the students of class 3-E of Kunugigaoka Middle School find themselves confronted with an enormous task: assassinate the creature responsible for the disaster before Earth suffers a similar fate. However, the monster, dubbed Koro-sensei (the indestructible teacher), is able to fly at speeds of up to Mach 20, which he demonstrates freely, leaving any attempt to subdue him in his extraterrestrial dust. Furthermore, the misfits of 3-E soon find that the strange, tentacled beast is more than just indomitable—he is the best teacher they have ever had! Adapted from the humorous hit manga by Yuusei Matsui, Ansatsu Kyoushitsu tells the story of these junior high pupils as they polish their assassination skills and grow in order to stand strong against the oppressive school system, their own life problems, and one day, Koro-sensei.
