Shizuku Kurogane

"I'm not as nice as Onii-sama, or as gentle as Stella-san, so I can't help but cut an enemy who attacked me to shreds. You chose the wrong foe."

- Shizuku Kurogane

Shizuku Kurogane is the youngest child and daughter of the Head of the Kurogane Household Itsuki Kurogane, as well as the younger sister of Ouma and Ikki Kurogane. Unlike her older brother, she was well-respected as a child and was even forgiven due to her talent as a Blazer and was the only person in their family who didn't despise or look down on Ikki for being an F-Rank Blazer and was saddened after he left. Shizuku later transferred to Hagun Academy as a first-year student and earned the nickname Lorelei and she became the roommate of Nagi Arisuin.

Soon after the battle in Vermillion, she was promoted from a B-Rank Blazer to an A-Rank after bringing her brother back to life.

Appearance
"She had short silver hair and jade-green eyes, showing enough charm to fascinate everyone, and she wore a light smile on her flower bud-like pink lips."

- Shizuku arrives in Ikki's Classroom Shizuku is a petite young woman of a much smaller stature even for her age often referred to as a lolita, and being shorter compared to Stella whose the same age. She has short silver hair with several bangs covering her entire forehead, the middle portion of it comes close to her nose and jade-green eyes. She holds her hair together with a black headband that has white-pink flowers on both sides of it; in the anime both the flowers are pink.

During her childhood, Shizuku had much longer silver hair tied into twin-tails, but she cut it short after her brother's eventual departure as shown in the manga.

There have been situations where Shizuku wore different clothes, the most well-known and constant being the female school uniform for Hagun Academy. Aside from her school uniform, she dressed in a black gothic lolita outfit during her time out with her older brother, Stella Vermillion, and Nagi Arisuin; which she also wore during her childhood.

Personality
As a child, Shizuku has been shown to be a naive and sweet little girl who cared for her second older brother, Ikki Kurogane, unlike her relatives who treated him badly due to him being an F-Rank, which was viewed as a failure among their distinguished household.

After Ikki left the Kurogane Household, her resentment for those who ridiculed him had grown to extend towards the other Kurogane, even her father who continued to intervene in his success in becoming a Blazer. This also caused her rivalry with Stella Vermillion who soon became his roommate and lover causing arguments and fights between them, most of the time when Ikki is involved.

Among her friends, especially both Ikki and Stella, Shizuku is quite merciless in battle never going easy her even opponents, never hesitating to kill enemies as shown by Wallenstein, however, he somehow survived.
