Katsuragi is a short girl with long blonde hair that reaches past her thighs, and blue eyes.
Like most of the female characters of Senran Kagura, she has a highly developed, curvaceous figure, possessing immensely huge breasts that bounce and jiggle with every movement, large, thick thighs, and grandiose buttocks. She is commonly seen wearing a headband with laces on the left and right side of her head, a school uniform with a white shirt, blue tie, and blue and large yellow and blue boots. Katsuragi also wears a blue plaid skirt which regularly fails to cover her bottom, as her kicking based fighting style tends to easily flip her skirt up and reveal her blue and white strped panties.
Katsuragi has a habit of leaving her entire shirt unbottoned, she also truthfully claims to not wear a bra, revealing a monumental portion of her breasts and stomach, only covering enough so that her nipples don't show, and allowing her immeasurably large breasts to bounce and jiggle without anything holding them back.
When Katsuragi was still a little girl, she lived a normal life while playing with her pet dog, Choco. Her parents were both shinobi as they fulfilled missions that were issued to them by the higher ups. However, one day, both of Katsuragi's parents failed at one particular mission and were told to give up their lives as punishment. To avoid getting Katsuragi involved, the two decided to become renegade shinobi and ran away while abandoning Katsuragi.
Feeling sad and abandoned, Katsuragi thought to herself and decided that she will become a strong shinobi in order to atone for her parents' crimes while hoping that she'll be reunited with her family someday. At some point, she enlisted in Hanzō Academy.
During her first year, she encountered a student that goes by the name of Ikaruga. As much as she tries to interact with her, Ikaruga ignores her. This annoyed Katsuragi to no end as she tries to get along with her. As they interact with one another, Katsuragi learned why Ikaruga has been acting the way she has been, which caused her to remind herself on how lonely she's been since her parents left her behind. As the two started to understand one another, they eventually started becoming friends.
During her second year, she and Ikaruga helped another student, Asuka get through her first year in the Academy. However, during a training session, there was an accident that caused Ikaruga to injure Asuka. Katsuragi figured that Ikaruga was still bothered by something, so she asked her to come to an open field, where the two will fight one another to be able to escape from their problems.
After the fight, the two were able to escape and their friendship was solidified.
Katsuragi was reading the "Super Dish Gourmet Cook-Off" flyer in her hand. She was surprised to know that the grand prize is a Secret Ninja Art Scroll that could grant any wish your heart desires. Thinking about the scroll and what she could do with it, Katsuragi started to laugh out loud. What she wants the most is being able to have all of the boobs in the world. She looked up at the sky and started crying out thank yous for this possibility.
However, Katsuragi realized something. She wondered who would put the scroll up as a prize for a contest. Quickly though, Katsuragi shrugged it off. She was never a deep thinker, so she decided to go along with this. She believes that it's better to act with instincts and to not let questions get in the way. Katsuragi looked up towards the sky once again and cried out more thank yous, but now combined with her saying "boobs". With how much she thinks about boobs, she jokingly stated how she might as well be made of boobs. At this point, she had no idea what she was saying anymore, but she was still excited.
With that said, Katsuragi decided to head for the tournament.
Katsuragi crossed paths with Mirai at the first match. Mirai was ready to go, but Katsuragi told her that she passed. Confused with what Katsuragi was talking about, Mirai questioned her. Katsuragi responded by saying how it's not all about being big and the fact that there are different shapes and sizes everywhere. She then told Mirai that she is welcome to join her paradise. Mirai still didn't understood what Katsuragi was talking about.
Katsuragi continued by saying how there's nothing to worry about and how no one will make fun of her in Katsuragi's paradise since the paradise accepts all women. Sorta understanding what Katsuragi is talking about now, Mirai's eyes widen and asked if that's true. Katsuragi nodded and mentioned how all women equals one world. Mirai went back to be confused but now she feels moved by Katsuragi's words, but then she came back to her senses and mentioned how she mustn't stand down now and win the tournament no matter what Katsuragi says.
After the match, Mirai was disapponted from losing to Katsuragi. Katsuragi told Mirai how she'll come back for her after she creates her paradise with the Secret Ninja Art Scroll. She then told Mirai how she's not alone and she'll never forget her. Mirai understood and Katsuragi became even more determined to creating her paradise.
In the Fourth match, Katsuragi crossed paths with Hikage. Hikage noticed Katsuragi acting a lot different than usual, but then she figured that Katsuragi is being her usual self. Katsuragi requested Hikage to join her paradise of boobs. However, Hikage didn't understand what she meant by that. Katsuragi then explained what her paradise will be like.
Jokingly, Hikage called Katsuragi's paradise some version of Hell. With enthusiasum, Katsuragi responded by putting some emphasis on how it's her paradise. Hikage then declined Katsuragi's offer and asked why does she want her to be part of it. Katsuragi told her to not worry about it and to just come along. This caused Hikage to not want to take part of the paradise at all. Afterwards, the cook off between them started.
After the match, Katsuragi once again told Hikage to come to her paradise since she has won the match. Hikage started to fear what would happen if she does go to the paradise. Katsuragi insisted that it will make things even more exciting and fun. To herself, Hikage figured that Katsuragi has now been hypnotized by boobs.
In the Fifth match, Katsuragi crossed paths with Homura. Homura commented how facing off Katsuragi will be exciting for her. Katsuragi told her how her boobs must come to her paradise as soon as possible and how she'll win no matter what. Feeling embarassed, Homura wanted to call Katsuragi "tits-for-brains," but decided not to since it would be like she's complimenting her. Katsuragi mentioned how Homura doesn't realize how valuable her body is with her sun tan her natural skin tone. Homura decided it's about time for her to stop Katsuragi here and now from being even more perverted. Katsuragi responded saying how no one is going to stop her and her boobs express in this tournament. Afterwards, the match began.
One tough match later, Katsuragi was victorious. Tears began to form in her eyes as she realized her paradise is almost at reach. Disappointed, Homura said to herself how the world has now ended. Laughing out loud, Katsuragi commented how every female will do her bidding, including Ikaruga, Homura, and even Daidouji. With all that said, Katsuragi obtained the Super Secret Ninja Scroll and wished for her paradise.
After creating her paradise, Katsuragi noticed how every women are now doing her bidding. All the boobs are now under her rule. It's now a world perfect for someone like her. Whatever Katsuragi orders, the women followed them no matter what. Katsuragi has now become the queen of boobs. Now that she obtained her most desired, Katsuragi was now able to think. She knows that most people's lives are filled with struggles and how there are times where you want to run from your troubles and give up on everything. However, as long as you don't give up and keep on moving forward, your dream could become a reality. That is why everyone has to keep on living until the very end since living is what makes life worthwhile to you. To end it off, Katsuragi said "Boobs go jiggle-jiggle-jiggle!"
According to the Senran Kagura: Official Design Works, Katsuragi was the first character design done by Yaegashi simply because he likes blonde hair. He decided on his own that she would be a character that used kicks which played a role in her design process, leading to her having the solid-looking boots she wears.
Katsuragi is one of the Hanzō team kunoichi to use her legs and kicks rather than weaponry.
Katsuragi's name means "Arrowroot Castle".
Katsuragi makes numerous claims that she wears nothing under her top. But through clothing damage she will be shown wearing a black breast harness-like piece that covers her lower chest.
In Dead Or Alive 5 Last Round, Tina dresses like Katsuragi as a DLC costume.
During Development, Katsuragi was planned to be the main character of the Hanzō girls instead of Asuka. But due to similarities she has with a certain female protagonist of another fanservice series, Hakufu Sonsaku from Ikki Tousen, it was decided Asuka would be a better choice as the lead character to possibly avoid a lawsuit.
As of February 11th, 2016 she is currently ranked as Number 3 in Watchmojo.com's: "Top 10 Female Anime Perverts", as well as appearing on the video's thumbnail "attacking" Asuka.
