"Tear my enemies asunder, Sphinx!"

- Rinna Kazamatsuri

Rinna Kazamatsuri is a member of Akatsuki.

Appearance
Rinna is a petite girl with pink hair dressed in a pink dress. She has an eye-patch patched to her right eye.

Personality
Rinna seems to be very arrogant of her own powers as she seems to talk down to Renren and continues to call Renren human believing herself to be above human level. However, it seems she also is very courteous to other people whose strength she respects, as shown with Ikki when she offered him a job to be her servant based on what she had seen.

History
In her childhood, Rinna found Charlotte Cordé alone on the streets, and decided to make Charlotte her maid. Charlotte became extremely loyal to Rinna, wanting to repay her kindness in any way. Rinna also adopted a lion named Sphinx.

She then became step-sisters with Sara Bloodlily after Sara was adopted by Rinna's father Kouzou. The girls later joined Akatsuki Academy due to Kouzou and Prime Minister Tsukikage being old friends.

Akatsuki Strikes
Rinna is seen riding her lion, Sphinx, going to Hagun Academy, along with the other members of Akatsuki, with the intentions of destroying it. After they have done so, the Hagun Academy's participants in the Seven Stars Sword Art Festival have arrived. Akatsuki is cut down easily largely due to Alice betraying them. However, it is revealed that they had seen Alice's betrayal coming and had prepared clones of themselves in their place.

Rinna faces against Renren and easily defeats her with not much trouble as the other student council members are defeated as well. The Akatsuki members have decided to go after Stella and the Hagure sisters who had escaped and are able to catch up to them. However, they are stopped by Nene who is able to easily overpower them, except Ouma. Rinna and the other Akatsuki members have decided to retreat since they had done what they came to do.

Party Crashers
Rinna is seen at the party with her maid, Charlotte Cordé, confronting Ikki and Shizuku. She offers Ikki a job as her servant, revealing that she is very well off. Although Ikki initially refuses the job offer he does accept her business card. She then leaves with her maid.

One vs Four
In the preliminary round of the Seven Stars Sword Art Festival, Rinna accepts Stella's challenge to fight against her, alongside Hiraga, Yui, and Mikoto. Sphinx is scared off by Stella, after seeing Stella's dragon-like aura. Rinna is protected from Stella by her maid, Charlotte. Charlotte is shown to be Rinna's ace, as she is able to fight against Stella equally, using Ichirin Junka, an ability granted by Rinna. Charlotte and are still beaten by Stella's overwhelming force. Rinna decides to drop out of the tournament, after her match with Stella.

Seven Stars Sword Art Online Third Round - Beginning
Rinna and Charlotte watch the match between Ikki Kurogane and Sara Bloodlily, Rinna's step-sister, together with Stella. She is also frightened by Charlotte, who keeps wanting Rinna to punish her due to her loss to Stella. Rinna believes that Sara will defeat Ikki, due to the variety of her abilities, but is surprised when she loses.

Rising Spirit
Rinna, along with Sara and Charlotte, meets with Bakuga Tsukikage, apologizing to him for Akatsuki's failure in the Festival. Tsukikage though says that he will simply need to think of something else, hoping that Rinna will help him in the future. Rinna happily agrees to help him. Just then, they are approached by Edelweiss, the world's strongest swordsman, who has come to watch the finals of the Festival.

The Festival is Over
Rinna participates in the party after the Festival. She is seen talking with Kanata. Kanata questions why Rinna joined Rebellion, and Charlotte tells Kanata that Rinna joined, because Rinna's father, Kouzou Kazamatsuri and Bakuga Tsukikage are old friends, and Rinna has been acquainted with Tsukikage since her childhood. Kanata tells Rinna she shouldn't do such criminal activities and even threatens to censor a manga Rinna likes, and so Rinna quickly complies to this. She then goes to a bathhouse with the other girls in the party.

Night of Massacre
After the Seven Stars Sword Art Festival, Rinna, Sara and Charlotte bring Tsukikage to the destroyed headquarters of Rebellion to meet Kouzou Kazamatsuri. They find out what happened there after Tsukikage uses his Device to see the event that occured.
