She was romantically involved with Guren Ichinose who Shinoa thinks killed her to acquire a weapon, however unknown to Shinoa is that Mahiru killed herself. Shinoa and Mahiru were rather close compared to their other siblings.

Also unbeknownst to Shinoa is that Mahiru requested that Guren pass Shikama Dōji to her so that Shinoa could survive the apocalypse. It eventually becomes her Cursed Gear scythe.

Her adoptive older brother, they are both friends with Guren. In the light novels, Shinya is shown to be kinder to Shinoa than the other Hīragis. Shinoa would receive his assistance when they worked together with Narumi's squad during battling in Nagoya where they defeated vampire noble Lucal Wesker. Helping Shinya to walk after rescuing him from thirteenth progenitor Crowley Eusford with Chess Belle and Horn Skuld, Shinoa would also comply with Shinya's direction to calm Yu down after he did not want to leave Guren behind. With uncertainty of their situation at arriving at Nagoya airport with no rescue in sight Shinoa looks to Shinya and is happy with his decision to head back and rescue Guren.

Kureto Hīragi

Shinoa's half-brother where they have a very distant relationship. They share the same father, Tenri Hīragi. He only cares about carrying out his duties as he tortured Shinoa at a young age.

Seishiro Hīragi

One of her half-brothers who is a part of the Japanese Imperial Demon Army.

Shinoa Squad

Yūichirō Hyakuya

Episode 2 - Screenshot 51.png

Shinoa acted as an army surveillance officer to watch Yu under a school setting until he made friends. She introduces herself and her purpose when Yu is not co-operating with the class teacher. Offering pointers on what he could say to make friends, Shinoa reports on him and watches him when they enter the training classroom for the Moon Demon Company. Later, Yu joins her squad where she still enjoys teasing him. Shinoa acknowledges his fighting capabilities of which she is impressed with and is pleased to see his developments such as asking whether they should retreat when facing a stronger foe. Shinoa is asked by Guren whether she has developed feelings for Yu, and she occasionally blushes when in close contact with him. However, she says she is uncertain about her own feelings, and Yu is oblivious to them. Understanding that Mika was Yu's family first Shinoa greatly respects Yu's resolve and feelings towards saving Mikaela and she agrees to help save him knowing he will do so anyway.

Later on, during a conversation with her demon Shikama Doji, Shinoa admits that she is jealous of Yu for being able to get attached to people and instinctively act on his feelings to protect them. She laments her own inability to act on her desires. Shinoa sacrificed herself to save Yu and his demon, Asuramaru from being overcome by Shikama Doji, becoming possessed by Shikama Doji as a result. Learning that Guren is heading for Yu she intends to help Yu.

Clear that she loved someone, Shinoa's desires for Yu were practically used to free herself from the confines of Shikama Doji. Repeating that she loved Yu, Shinoa let her desire run wild to the point she turned into a demon. With her body back Shinoa was relieved at seeing Yu.

Yoichi Saotome

Episode 4 - Shino pairing off with Yoichi.jpg

Finding him being bullied Shinoa encouraged Yu to intervene. Clear that Yoichi was Yu's first friend, Shinoa took Yoichi for herself in a group activity so Yu had to join Kimizuki and stated that they would be the best group. They attend the same classes together and Shinoa is alarmed when Yoichi is possessed by his demon where Guren has ordered him destroyed.

Before becoming Yuchiro's supervisor, Shinoa supervised Kimizuki and tried to teach him how to make friends. She was aware that Kimizuki had picked a fight with Yu who fought back but preferred to enjoy the show. He later joins her squad under her command. Shinoa was upfront on what Kimizuki would do if she really were manipulating squad members but agreed to discuss the matter as a team where they would be honest with one another. Although his swift response time makes him more difficult to tease than other members of her squad Shinoa would find a way by teaming up with Mitsuba to act as him and Yu being more than friends as a joke once.

Guren Ichinose

Shinoa works for Guren rather than the Hīragi family. They have a close relationship with Shinoa acting beyond her years around him. She follows his orders such as when she kept watch eye on Yu Shinoa was angered at feeling that Guren was behind Yu's transformation and more so at hearing him invoke his sister's name when using his weapon. He loved her sister, Mahiru Hiragi, who became the demon in his sword. Gathering her squad they decided whether they should stick with Guren when he could be using them to intimidate army higher ups and agreed to do so. Shinoa maintains trust in Guren but was taken aback when her jovial answer as to why they were late to the Ebina rest stop was shut down and she was shouted at. Rather than Yu it was Shinoa who was the one Guren wanted to punish as she had never experienced what it was like to lose someone. Shinoa became confused when he slaughters many of the humans and stabbing Kimizuki in Nagoya airport.

Thinking that they were all Shikama Doji's guinea pigs, Shinoa speculated that Guren had been secretly undermining the first.

She even attacks Major General Shinya Hiragi to save Mika's life, and was labeled as a traitor as a result.

She is happier with him not in their presence. After rescuing him for the information he has access to Shinoa is greatly alarmed at turning to see what the show is that Ferid mentioned was behind her. At seeing Ferid naked and in a state of regeneration Shinoa resorted to her scythe to cut Ferid's head off. She sees Ferid near her when the first is possessing her.

Shikama Dōji

Shinoa looks at Shikama.png

After her sister Mahiru extracted the demon from her, she forgot all about him. She regains her memory of him after Guren passess her Shikama Doji by Mahiru's request.

Shinoa has become very affectionate and playful towards Shikama-Dōji, always calling him "Shi-chan". The two shared the first character in their name, which alone, can mean "Four" or "Death". After he reveals his true personality Shinoa hears from him that she loves Yu and is much stronger than her sister Mahiru.[1] After Shikama Doji starts acting on his own and manifests without Shinoa permission she is tempted repeatedly with thoughts of turning Mika into a human and restoring Yu's humanity. He reveals that he is not actually a demon and would happily possess her instead of Kureto, this conversation angers Shinoa as she tells him to shut up to the point of shouting and silence him in rage which then she wakes up and states he may have possessed her sister Mahiru.[2] She was able to fend off Shikama Doji possession for a long time thanks for Mahiru protection. He later invades Yu's heart for the intent to draw out Shinoa to possess her, which the latter succeeds. Shinoa's humanity and heart are now gone as Shikama Doji has complete control over her body.

Even when possessed Shinoa's body benefits from the protection of the first who will protect his host. When Shinoa was about to be attacked by Ferid, he mercilessly sliced Ferid in half and cut off his sword wielding arm. Shinoa's body is used to attack Guren, Shinya, Kureto and Mika. After Saito has arrived he engages in a battle against Shikama Doji who is in Shinoa's body with the goal of restraining him.

At the risk of her body breaking Shinoa has Shikama Doji leave Shinoa's body due to the sinful keys which were used by Guren, Mahiru and Noya. This also seals him away 'for the time being' which he brings up before leaving her body. Suspecting that Shikama Doji may be weakened Shinoa derisively suggests he shake off what is making him uncomfortable, use her desires for possession, and comments how she has never seen him look this bad. Shinoa exploits Shikama Doji's state to try and possess him but then chooses to warn Yu of Ashera instead and she sticks her tongue out at Shikama Doji. With that challenged Shinoa drew on her desires for Yu to transform into a demon where she meant to overtake him.[3]


Knowing him as Yu's demon Shinoa also inferred that "Ashera" was another name for him.[4]

"It seems, unfortunately... ...That Asuramaru is an enemy. I heard Shikama Doji ordering him to capture Mika's soul."
—Warning Yu of the first's connection with his demon (Chapter 99 "Mortal Love" page 40-41)
