Mirai Kimizuki (君月 未来 Kimizuki Mirai?) is the younger sister of Shihō Kimizuki who was infected with the Apocalypse Virus despite being a little girl and was being treated in a hospital. Shihō joined the Japanese Imperial Demon Army in order to gain access to the military resources that were needed to cure her as the virus could not be treated in civilian hospitals.


Human Edit

Mirai is a young girl with long reddish brown hair and reddish pink eyes. She has purple curse marks from the Apocalypse Virus on the left side of her face that fluctuate with her current state of welfare. She is most often shown wearing a hospital gown.

Seraph Edit

Mirai no longer has the curse marks on her face, her eyes are dark with peculiar markings on her irises, and sports two pairs of large feathered wings. When Abaddon possess her, the demon manifests in a giant dark figure with many wings and an irregular form behind her. She is still in the hospital gown and is barefooted.

  • Anime: The curse marks remain and increase.[2]


Before the apocalypse, Mirai lived a normal life with her parents and older brother, Shihō Kimizuki. At some point, she and Shihō were experimented on by the Hyakuya Sect to become weapons of mass destruction known as the "Seraph Of The End" to destroy the world. Guren knew of this beforehand, thanks to intel provided by Mahiru eight years ago. That tragic night, the Apocalypse Virus got released on Christmas 2012, killing her parents and becoming infected herself, even though she was a little girl, forcing her brother to take care of her.

Three years later, in 2015, Mirai fled with Shihō, though he had to carry her due to the Virus making her too weak to move, thus making things difficult for her older brother over time.

Story: Vampire ReignEdit

Second Shibuya High ArcEdit

Mirai debuts when Shihō and Yu (due to being handcuffed to each other) leave in the middle of their exam to come see her in the infirmary. She is being tended to with a combination of medical technology and spell tags to mitigate the effects of the curse. The healthcare provider informs Kimizuki that she pulled out of danger this time, but the treatment available to civilians is not enough. Kimizuki tells him that soon he will be in the Moon Demon Company and will be able transfer her to an army hospital.

After they leave, Kimizuki blames Yu for letting his grades drops which affects in ability to enter the Moon Demon Company and because of that, Mirai would not be able to be saved. Yu tells him to not give up on her and Kimizuki soon thanks Yu for letting him be able to be there with her when it counted.

Mirai as an experiment

Mirai reappears again much later in a Demon Army helicopter, she screams about pain while scientists watch and observe her.

One orders an increase in dosage which another scientist tries to protest. The one from before says that it's fine as Kureto Hīragi gave him the order to increase the medicine dosage. Mirai begs for them to just kill her before receiving an injection which causes her immense agony to the point of pleading for her big brother while also causing the curse marks on her face to disappear. Two pairs of feathered wings then erupt from her back as her screaming stops.

Episode 24 - Screenshot 45

Mirai's Seraph appearance

She is next seen where she erupts from a Moon Demon Company van and floats in the sky with four large feathered wings and a single long trumpet before her. In this form she curses the sinners and says ruin will fall down upon them. Kimizuki recognizes her, shocked and horrified.

Chains erupt from the remaining van and pierce through Mirai, making her scream in pain as a magical circle appears behind her. While Kimizuki is enraged, Guren stabs him from behind and tells him to hold still because they have not yet offered enough blood to control Mirai.

Up above, a black aura appears from Mirai's back. The soldiers announce that the fifth trumpet is transforming into an angel of destruction to smite mankind. Although they have not offered enough sacrifices yet, they have achieved the proper state, and Kureto's subordinates claim they are successfully controlling a Seraph of the End. He orders Aoi to feed the rest of the sacrifices to the demon Abaddon to stabilize it. The demon's power rushes out and consumes both nearby vampire and human soldiers while they look up in horror.

The demon becomes fully stabilizes but a few moments later, Yu awakens in his Seraph form and destroys Abaddon's manifestation.
