Shinoa Hiiragi

Shinoa Hiiragi is the main female protagonist of the Seraph of the End anime and manga.

Shinoa is the the younger sister to Mahiru Hīiragi. She is from the prestigious and rich Hīragi Family and was appointed as Yūichirō Hyakuya's supervisor during his suspension. She was a sergeant of the Japanese Imperial Demon Army and the leader of her squad in the Moon Demon Company. She was ultimately possessed by Shikama Dōji shattering away her humanity.

Appearance
In the light novels, Shinoa is described as an adorable and beautiful young girl with shoulder lengthened ashen hair same as Mahiru's, and a dark magenta bow at the end of a twisted braid. Guren describes her as having clear, piercing amber eyes that seemed to stare out at the world and skin so pale that it was almost transparent. On her left arm, she has a black shackle.

She wears a black sailor-like uniform with 10 yellow buttons along the side of the dress. Placed before the last set of buttons, she wears a silver belt, and on her hands are white gloves. There are 2 green stripes around the wrists of the uniform, and on the neck side, she wears a dark pink bow.

Shinoa is shown to bear a striking resemblance to her sister as she shares the same face characteristic and hair. Also, she has a very short, petite and skinny figure and her hair is pinned up at the back with a black bow with side braids.

At the beginning of the series, she is shown wearing her school uniform, a sailor fuku which consists of a grey blouse with black cuffs that have teal trim in the middle. It has a black sailor-style collar with has teal trim and a single five teal petal design in the middle. The ribbon of the uniform is also teal and is tied in the front and laced through a loop attached to the blouse. The bottom is a black skirt. She wore it with dark blue knee high socks and white shoes.

After Yūichirō was accepted into the Moon Demon Company, Shinoa is often seen wearing her Japanese Imperial Demon Army (JIDA) uniform which consists of a long-sleeved black coat with a standing collar which has a magenta bow tie around it. The coat has two rows of gold buttons on the front, light green details including the shoulder epaulets, which has a fourragère passing under and around her right side. Along with that, she wears a pair of white gloves, an armband on her left arm, and a white web belt with a gold waist-plate. She also wears the standard black skirt, dark gray thigh-high socks and knee-high black boots.

Her casual appearance doesn't differentiate much from her JIDA uniform. The minor differences are that she doesn't have her gloves along with the bow tie on her collar and wears a white long-sleeved dress shirt with a camisole over it.

Personality
Shinoa has a sarcastic, apathetic attitude and doesn't put much emotion into her words. She loves teasing others and is quite dry-humored. Shinoa generally tends to smirk before teasing or performing her antics at others, putting them in uncomfortable situations. She can be proud and arrogant but has a nice, joyful and cheery part of her. Rarely, Shinoa shows that she can have a scary and manipulating side. She is very secretive, and although she is inexperienced in both battlefield tactics and fighting (when compared to Guren or her older siblings), she leads her squad well and remains levelheaded in battle. However, she is very determined and strong because of everyone. Some days, she lacks self-control and will get mad easily, increasing her tone and growling. Shinoa hates showing her love and appreciation for Yuichiro, as she says she wants to keep her feelings "professional" and because of this, she shows to have a tsundereside.

Due to her circumstances surrounding her family, Shinoa grew up without knowing what a sibling is, and never truly cared about anyone until her current squad was formed. She greatly respects Yūichirō's resolve and feelings toward his family and wants to help him. She shows surprisingly little emotions when talking to Yūichirō about her sister's death, suggesting that Shinoa is emotionally detached to people she knows and keeps her friends away at an arm's length.

In Catastrophe at Sixteen, Shinoa is revealed to be a lonely girl, shut away in an apartment on her own. The only friend she has is her older sister Mahiru, but in the end, the demon possessing Mahiru consumed her humanity, and that shattered Shinoa's resolve to form bonds with others. When Shinya and Guren offered to take care of her after seeing the mess in her apartment, she pushed them away, claiming that they're only there to use and exploit her. Shinoa's lack of faith in others caused her to believe that she can only rely on herself, as there's no one else to trust. Because of this, she trusts people less and is more negative about things. She appears to be negative in trust, and messy if she's alone.

Shinoa shows that she doesn't care about the conflict inside her family, claiming that family conflicts are what caused the death of her older sister. Unlike Kureto, she lacks ambition and only wants to serve the army well. She explained to some soldiers that she doesn't actively seek a rise in rank, and her lack of ambition (and Mahiru overshadowing her) is what caused her to be cast out from her family.

However, it wasn't until after she lost the mock battle between her squad and Guren's three-man squad, did Shinoa finally realize the fear of losing someone important to her, and even a tiny mistake or her pranks can cost her family their lives. Also, she and her squad can grow even stronger and the closer they grow, the more powerful they'll become.

Shinoa has a vulnerable complex about her short stature when Yūichirō and Shihō teased her for being too short to drive a car, she then proceeded by materializing her Cursed Gear and "executed" them.

She developed feelings for Yūichirō, in which she is uncertain of. This is shown more when she later speaks with Shikama Dōji.

As a leader of her squad, Shinoa takes a calm and strategic approach to situations.

After being possessed by Shikama Doji, her personality changes drastically as Shinoa becomes merciless, violent and ruthless, attacking anyone who might pose a threat to her (under Shikama Doji influence) this is largely shown when she attacks Ferid and Crowley whom Ferid tried to kill her. With Shikama Doji in control, she also attacked Guren, Shinya, Kureto and Mika for no reason at all, just for killing them.

Natural Abilities
As a member of the Hīragi Family, Shinoa proves herself qualified to handle a weapon of the Black Demon Series as seen when Guren engulfed the classroom with his Cursed Gear's aura, albeit the weapon she wields is a lower class. As leader of her squad, Shinoa remains levelheaded and takes an analytical approach at dire situations. She is knowledgeable about weapons, demons, seraphs, and vampires as well as the Demon Army politics. According to Shikama Doji, she is the first person to actually wound him by throwing her scythe at him despite being an immortal being.

In the Light Novels, Shinoa is good at martial arts, and Guren once mentioned that she's an incredibly gifted child that looks like a genius. She additionally is shown being able to wield her scythe extremely well, despite her young age like when she was able to deflect several bullets at once when protecting Goshi.

Strong resistance to demons: Shikama Dōji has said that Shinoa is the perfect product of the experiments, and that she is able to resist any demons that she comes in contact with. This is due to the fact that she doesn't have a lot of desires in her heart. Shikama Doji also mentions that Shinoa can contract to any number of demons without being possessed. Shinoa is still unaware of this. As of eight years later, Shikama Dōji stated that in hundreds of years of possessing the Hiragi family, there has never been a vessel of her caliber, noting that there would be no need for him possessing Kureto any longer once he starts possessing Shinoa. Which the latter succeeds in doing so.

After Shikama Doji possessed Shinoa, her strength increased tremendously. Overpowering and defeating Ferid effortlessly. Shinoa has also shown the ability to summon and materialize multiple scythes to attack.

Equipment
Talismans (Light Novels exclusive): Shinoa is seen to be skilled with talismans as Guren noted her as an exceptionally gifted child, her talents befitting of her family name.

Hand-to-Hand Combat Skills
Shinoa is shown to have a strong range in battle, she can jump very far and sprint very fast. She has good strength in her arms, and legs for kicking skills. Most likely provided to Yuichiro.

High Agility
Shinoa does have high agility, which causes her to jump and move easily, jumping over fences and walls way taller than her.

Cursed Gear

 * Shikama Dōji 「Four-Scythe Child」: A manifestation-type demon weapon from an unknown series. Shinoa takes out a pen-length black rod and spins it, which then transforms into a black massive scythe with a thick, black aura around it. She can call out the demon, which she fondly addresses as "Shi," inhabiting it out of the weapon to attack an enemy. It is strongest at mid-range. Her primary ability is to detect anything that comes within the attack radius of her scythe.
