Suzuri is a slender light-skinned woman with short pink hair that is parted to the side.
She is wears a white aikidogi with a black hakama when training but otherwise is usually seen wearing a kimono.
Suzuri is shown to be woman who uphold the honor of her family and dojo as she doesn't accept anyone from her family to lose in a fight. While she does care for her family she is shown to be the dominant one as both her husband and daughter are afraid of her due to her incredible strength.
Suzuri was the daughter of a family which ran a dojo teaching the Sumeragi Style of sword fighting. At the age of seventeen, she was the best in the dojo with no one other than her father being able to land a hit on her. Rumor circulated around the students that if one could get a hit on Suzuri they would get to marry her. One day, she entered the bathrooms naked to find Susumu cleaning. Just as Suzuri was about to hit Susumu, the two of them slipped and Susumu accidentally landed a hit on her with his broom. Being the first person aside from her father to land a blow on her, she had Susumu take responsibility and the two would marry six years later.
She first appeared after learning that Sunao not only lost a fight with Kazuya but had the family sword damaged. She then informs her that because she lost, Sunao couldn't inherit the school as they were known to be undefeated and told her that there are two ways for her to inherit the school; Either kill Kazuya so that the loss wouldn't count (which she later say that be impossible due to this day in age) or marry him so that the lost wouldn't count.
Later when Kazuya was walking towards the Sumeragi's home, she spotted Susumu standing in the front door as he prepared to attack Kayuza for hurting Sunao but she stopped and attack him as she welcome Kayuza to the house. She then followed both Sunao and Kayuza after it they lied that they were dating (in order for Sunao to inherit the school due to her lost against kazuya) even giving them some help to prove they were dating such as having them take a bath together or sleeping in the same bed. Unfortunately Susumu attempted to stop them from getting to close, resulting in him striking Sunao instead of Kazyua (because he though Kazuya was on top instead of Sunao) but before he could finish the job, Suzuri appeared and beat the living day lights out of him. After beating him up Suzuri told Kazuya and Sunao to continue but they explain that they have finished and even showed a blood mark on it, which made the Suzuri happy but Susumu angry.
However Suzuri took a closer look at the blood mark and grabbed Sunao and opened her legs to discover that she's still intact, revealing the blood mark was from Sunao's thumb (as a result of her father). Learning that she was lied to, Suzuri revealed a key that led them to the punishment room as she plans to punish them for lying to her.
- Suzuri's surname Sumeragi means "emperor" (皇).
