Shizuno Urushibara (漆原 静乃, Urushibara Shizuno?) is one of the female protagonists of the Seiken Tsukai no World Break series.


Shizuno is a teenage girl of average height who has long maroon hime-style hair and green eyes. She has white skin and a rather more mature well-endowed body (rivaling that of Elena Arshavina or Sophia Mertesacker) than Satsuki, which is often brought up by her in jealous fits. She is considered to be highly attractive by her peers, who sometimes envy Moroha Haimura for their close association.

She usually wears an academy uniform or training outfit at the academy. Outside of school, she wears casual clothes such as a purple dress which goes along with her wealthy upbringing. She also has a red mark on one of her breasts, which stems from when she was branded as a slave in her past life.

Shizuno has a tendency to kiss Moroha in almost any situation.

In the anime, Shizuno is portrayed as having a very deadpan personality along with a monotone voice. She rarely shows any emotion save for comical moments but usually gets into a one-sided argument with Satsuki which she always wins, regardless of the situation.

Shizuno is also an intelligent young woman who seems to know a lot more than what's going on. She is also slightly perverted, always impulsively kissing Moroha Haimura or shoving his face into her breasts rather intentionally or out of habit, often causing dismay towards him and Satsuki.

However, Shizuno does care about her friends as shown when she offered her email address to Satsuki even after arguing with her at various times. She was also quick to genuinely apologize to Satsuki for a rude remark about her chest size when seeing that she was self-conscious about it. She even gave encouraging words as Satsuki was angry she possessed both a body and manners, which she lacked in.

In terms of her family, Shizuno's life has been decided for her since she was a child, something which she noted out on how she dislikes her home, and as to how her brother is rather selfish, and easily noted, strongly controls her. In her family, she isn't allowed interests but tells Moroha that her interest at certain points is sleeping, because she can dwell in happiness.

She has strong feelings for Moroha as whenever she hears Satsuki arguing with other girls, especially Elena Arshavina, of who will be Moroha's lover, Shizuno is shown to understand how Moroha would feel about that happening when he comes back from a mission. Also, her deadpan personality does not stray her away from other emotions or traits. When she was told by her brother that she would be studying in England, this greatly saddened her, mostly because she didn't want to be separated from Moroha, something she makes clear to him after he barges in on her home. Her feelings may have grown after he gets her away from her brother and duels Sir Edward Lampard for her sake. Also, in contrast to her not talking about their past lives, she gives him a vague hint about it as she didn't want to pester him like Satsuki.


From a young age, even before she began attending Akane Academy, Shizuno's older brother has trained her as a Dark Mage. As an Urushibara, she was not allowed to have any personal interests and is expected to become an executive of the Japanese branch, like her brother.

As Moroha noted, she was treated more like a tool rather than a person by her own family. It has been stated by Maya that Shizuno became much happier when Moroha came to the school.

Witch of Netherworld Edit

The Witch of the Netherworld and her husband

Shizuno is the reincarnation of the Witch of Netherworld and/or the King's Witch. As the Witch of Netherworld, she was the wife and right hand of Shu Saura, one of the past lives of Moroha. Before this, both were seen to be enslaved in some sort of encampment, where she was responsible for feeding him, and it seemed to have been the place where they first met. At some point, they escaped, with Shizuno revealing that he had saved her from being a slave, and such, she was chained to him, and would always remain by his side. They eventually became husband and wife.

In the present day, Shizuno addressed Moroha as Oh, my dearest King, implying that she still loves him. Shizuno has shown to have memories of her past, despite it only being small glimpses, but avoids telling her connection to Moroha when asked, until it's the right time to tell him. She also avoids the topic when he asks her if she was really the Witch of the Netherworld.

In several flashbacks of her past life, she is shown to always be by his side, being his support, vowing to stay by his life, no matter the circumstance, with him being the one who chains her, no longer being bound by others.

In the anime, She was frozen in a block of ice by the black dragon and was killed, as its tail shattered the ice.

Powers and AbilitiesEdit

Shizuno is a skilled Kuroma of a Rank B, due to her having prior experience in using her mana due to all the strict lessons provided by her brother. She was able to instruct Moroha Haimura in using his black magic teaching him a number of spells. Though Shizuno appears to be a "Blockhead", whenever getting serious, her mana is shown to be stronger than that of Tokiko Kanzaki, the Vice-Captain of the Striker Unit and Mari Shimon, the Principal of Akane Academy with Elena stating she is a Rank A.

Despite being a Kuroma, Shizuno wields an ID Tag, which she uses to summon her Dragon Cane Nargravitz, a magic staff that has an ice crystal embedded in it, which is able to turn into a dragon that protects her from harm and attacks her enemies depending on the situation at hand. She was able to force Elena to use her own Origin, Magic Sword Leprazam.
