Ерза е един от най-силните магове в гилдията Фейри Тейл от едноименната манга, на 19 години е. Чрез магия може да сменя облеклото си както прецени според ситуацията - всеки екип обикновено включва комплект броня + оръжие/я - в зависимост от нуждите. Естествено има и облекла, не предназначени за бой - пр. бански, или вечерна рокля. Темпераментният й нрав често я забърква в доста комични ситуации измежду по-сериозните битки.

Minato's fifth Sekirei. She first 'met' Minato at the "Izumo Inn" after she stumbled into his bed in a drunken stupor. It has been hinted that she knows Minato's father. Despite Minato's lack of 'manliness', his concern and love for his Sekirei caused Kazehana to develop feelings for him and she eventually become his Sekirei. Like Tsukiumi, Kazehana addresses herself as Minato's 'wife'. Normally, Kazehana displays a very relaxed personality and often becomes giddy when discussing matters of love. However, when she is serious she displays a lot of power and lets nobody, except the MBI Director and Miya, talk down to her. She knows Uzume's secret, and while she doesn't condone Uzume's actions, she understands Uzume's motives (love for her Ashikabi). Kazehana was once an 'S Plan Guardian', one of the five members of the 'first generation' Disciplinary Squad. Kazehana has the ability to control and manipulate wind, which also grants her a limited ability to fly; her name means "wind flower" ("kaze" - wind, "hana" - flower). She loved MBI Director Minaka Hiroto, when she confessed her love to him she was rejected as he loved someone else. She seems to show hatred towards Takami Sahashi as she could be the person Minaka Hiroto loved. Miya's nickname for Kazehana is "Pubic Obscenity".

Her name means "moon sea". Miya's nickname for Tsukiumi is "Walking Tap", because of her ability to control water.

Motoko Gettou is the protagonist of the series. Motoko's mother died when she was very young and she was adopted by three combat specialists. These "Three Fathers" trained her in karate, swordsmanship, submission techniques, close quarters combat and the handling of firearms. As a result of their rigorous training, she developed three distinct personalities collectively known as HiFuMi *. Motoko sees HiFuMi as a burden and wants to live a normal life, but knows they are just trying to look after her safety. Though she is shy she slowly starts to warm up to Kouskegawa, but nervously states they are just friends every time someone suggests that they are a couple.

* HiFuMi ("Hibiki", "Fujiko" and "Mikiri") appears when Motoko experiences strong emotions. The three personalities are in constant communication with each other, but cannot communicate with Motoko. The 3 of them are essentially younger, female versions of the "fathers".
