|Hair color||Light Brown|
|Status||Alive (as of Rozen Maiden 0)|
Hana has short, wavy, light brown hair and usually has some sort of hat covering it. In flashbacks, her hair was a straight texture, suggesting that the wavy texture is her stylistic preference. Her eyes are brown.
Since she personally identifies as a moga ("modern girl") she owns and wears many different western-style clothes and frequently appears in different clothing. Because of this, the only reoccurring outfit she's seen in is her work outfit.
Hana is ambitious and quick to be envious, especially towards her sister, Kiku.
Her interactions with Souseiseki help her overcome her past with Kiku. After she finds out that her workplace will be destroyed at some point and that Souseiseki knows why, the two become involved with Kiku and the young master who are trying to solve the problem at large. She is at first unwilling to let Souseiseki spend time with the group but eventually she loosens up and even ends up herself joining them more often. When Souseiseki forces Hana into changing her mind on an order so Souseiseki can do what she wants to do and this ends up getting Souseiseki kidnapped, Hana decides to forgive her and says that it's all in the past showing Hana's increasing ability to make peace with past events.
She has the ability to enter the Miniature Garden in the N-Field through use of her workplace elevator. This is a side effect of the building being where the world and the Zeroth Doll's dream meet. She appears to be the only person capable of this using an elevator.
Hana grew up in the Japanese countryside with her sister, Kiku. Hana fell out of a tree when she was a child and Kiku had to carry her back, an event that's left her with a fear of heights. Growing up, she was known as the most beautiful girl in the village and likely because of this, Kiku thought that Masao's frequent visits to their house was because he was interested in Hana and she told Hana this. She thought that maybe it would be ok if she became his wife since she wanted to move to the city and he would be a good method. Masao eventually confided to Hana that he was interested in Kiku and Hana couldn't bare to see either of them around so she moved to Tokyo on her own.
After moving to Tokyo she cut off contact with Kiku and even her parents. She became involved in moga culture and at some point cut her hair.
She goes missing after her workplace elevator takes her to a "thirteenth floor", which actually takes her to the Miniature Garden. She runs into Kanaria and Hinaichigo and spends time at the dinning table with them, thinking of this as a weird dream. The two dolls inform her that time has been stopped for a while now and if they can fix a watch it will resume again. They go to a well where Kanaria explains that if they could drip the watch into the waters of the well it could fix itself. Kanaria gives Hana her umbrella and then she and Hinaichigo push Hana into the well as Hana protests this, citing her fear of heights. As she descends the well, she sees images from different points of time including one of the Youunkaku destroyed, an image of Shinku is far below her and she looks up to see Suiseiseki's disembodied eyes through the lens of the binoculars large and staring down at her. She exits the well and lands on the top of the Youunkaku, passing out.
She recovers in the first-class area of the tower to Kiku's voice. Hana figures that she just had a dream. When Kiku hugs her in relief, she pulls away and asks Kiku to not bother her again. She later discovers that she's been gone for two days, that she still has Kanaria's umbrella with her, and that it was no dream, the tower she saw was of the future. The young master visits her at work and asks her how she managed to get into the N-Field, Hana defuses to answer him. She decides that it would be a good idea to learn how she did it once the time came that the tower falls. She discovers Souseiseki's case in the elevator and takes it home.
Kiku is Hana's older sister, though the two were born in the same year. Hana has noticeable feelings of inferiority towards Kiku and tends to get envious when Kiku is given preference. She used to have more positive feelings towards Kiku, but this changed after Masao, a man she liked, asked Hana if Kiku was seeing anyone. Hana was very disappointed and her feelings towards the both of them turned sour. 
After Hana moved to Tokyo, she did not talk to Kiku for a while. After Hana meets her again, she makes it clear that she does not care about her anymore. As she interacts with Kiku, she tends to be boastful towards her in attempts to make Kiku envious. However, with more interaction between the two, her negative feelings disappear and she gains respect for Kiku. After Kiku leads the Sui-Sou Detective Team to confront Ageha's father, Hana tells Kiku how inspired she was by this. 
Hana would later tell Kiku that she is allowing Kiku to ask her for company now. In response, Kiku tells Hana that she'll protect her. 
Souseiseki is Hana's Rozen Maiden. She discovers Souseiseki's case after a ride in the elevator, deciding to take it with her back home.  Hana's initial reaction to Souseiseki is of adoration, commenting on how handsome and prince-like she is. She becomes very protective of Souseiseki when the young master shows up after Souseiseki is wound up and he demands that she pick him to make a contract with. Later that day she and Souseiseki form a contract. 
The two are shown adjusting to living together fairly quickly, though Hana occasionally finds Souseiseki hard to deal with. As Hana has taken up detective duties in addition to her job, it seems that Souseiseki has taken up some of the chores in their living space to ease Hana's workload, as she mentions doing Hana's laundry. It's also mentioned several times that when night comes Souseiseki makes Hana a cup of tea.   She carries Souseiseki in a bag most of the time, but once tried to hold her in her arms pretending to be a ventriloquist saying that they had practiced this. 
Hana blushes a lot in response to Souseiseki, which likely stems from a romantic attraction to her. She calls Souseiseki "prince" several times and also mentions that Souseiseki looks like "the foreign prince of my dreams".  When the two have a disagreement Souseiseki gets Hana so flustered that she begrudgingly gives in to Souseiseki's desire.  When the outcome of this event goes wrong, Hana tells her that she forgives her and Souseiseki apologizes. Hana reacts in surprise with hearts drawn around her. She later receives a rose from Souseiseki while in the Miniature Garden.  After Kiku shouts from the top of the Youunkaku, Hana also shouts, exclaiming her love for Souseiseki.  She is seen arriving to Souseiseki's aid in the N-Field after Suiseiseki falls apart. Hana is quick to notice Souseiseki's tears, and she comforts Souseiseki after the doll asks her for guidance. Later, Souseiseki begins to sing to unison with Suiseiseki's song. Hana takes interest in her singing and is the first to join her in song. They are seen holding hands singing together as everyone else joins in. In their final scene, Souseiseki apologizes to Hana for being late to the group's tea party. 
- Hana mentions that she and Kiku were born in the same year, though Hana is younger.
- Coincidentally, her job is the same occupation as Saitou's character in the play Practica Dolls. Both are elevator girls.
