Sirin was the Current Era's Herrscher of the Void and one of the main antagonists of Honkai Impact 3's main story line.


Sirin appears as a young girl. She has long purple hair and yellow eyes.

Her outfit changed 3 times during the course of the 2nd Eruption. She is first seen wearing a white lab gown before her full awakening.

After her full awakening, her outfit changed into a short tube dress. It was mostly white and purple; with reddish purple lines and small golden decorations on the front. She also wore a purple hair clip with red inlays, purple gloves with the same reddish purple color on her palms, and a purple choker with a yellow ornament. Both her arms and legs were wrapped in purple bandages.

After her ascension on the Moon, her dress changed dramatically and her pupils are replaced with yellow crosses.


Originally Sirin was a kind and caring girl, thinking of everyone as a friend. However, with the experiments in Babylon Tower killing all of her friends, she grew a complex for power and revenge, refusing to die, and suffering the abuse, she made the resolve to kill everyone in Schicksal.

After her partial awakening, she exacted her revenge on the 322 scientists of Babylon Labs. Her heart was filled with a deep hatred for Schicksal and its valkyries, and was so exacted on the idea that they were all liars that she would not listen to Theresa's words.

When she fully awoke as a Herrscher, her personality took a drastic turn. She became prideful, overconfident and arrogant: deeming humans as nothing but insects and believing herself to be the God's chosen one. She looked down on those less powerful than her. Even Bella was shocked to see what her best friend had become. However, deep down Sirin was still a young girl who needed someone she could believe in, despite not being able to believe in anyone at all. And so, she had an attachment to Cecilia that affected Kiana. It seems that in 2014, Sirin's personality is still this way.

It is also constantly hinted that Sirin is afraid of Siegfried after he crushed Sirin's forces, ripped her arm off, and removed the Gem of Serenity: her source of regeneration.


Sirin grew up in a small village in Belarus with her mother. Nothing is known about her other family members, if she had any.

At some point before the 2nd Eruption, Sirin's mother died from Honkai Radiation and she was taken in by Schicksal to be a test subject at Babylon Labs for their Stigmata Research. In these tests, she and her friends would be subject to being injected with Honkai Energy. The Scientists eventually discovered that Sirin had remarkably high Honkai Resistance and demonstrated the ability to absorb and neutralize Honkai Energy within her body. They hadn't been able to determine how she was able to do this, but believed it was very much what they were looking for.

Manga Story[]

In the year 2000, Sirin amassed enough power to massacre the 322 scientists in Babylon Labs; after which she began to absorb energy from the Reactor.

This prompted Otto Apocalypse to send an investigation team to Babylon Labs consisting of Theresa Apocalypse and Patricia Highsmith. There, Sirin was confronted by Patricia and Sirin defeated her. Teleporting away from Babylon Labs, Sirin was taken to a "Honkai Chrysalis".

After entering, she formed her Core and fully awoke as the 2nd Herrscher: the Herrscher of the Void.

Eventually she was found by Theresa, and Sirin showed her a flashback of her past in an attempt to recruit her to her cause. Failing to do so, Sirin resolved herself to eliminating Theresa. After defeating her, she was confronted by the Herrscher of Reason (the 1st Herrscher), Welt Yang.

In their battle Sirin overpowered Welt, but Lieserl Albert Einstein launched the Silver Bullet her way. Sirin didn't know what it was, but she knew it was dangerous, so she redirected it into the ground. Despite this, the resulting explosion was enough to stun her, freefalling to the ground below. Using his false Star of Eden, Welt created a Quasi-Blackhole to suck Sirin in to try and defeat her. He was then thwarted by a masked Clown.

Afterwards, Benares carried Sirin to the moon with the last of its strength, and Sirin used a large portion of her power heal it. She also gave it a pseudo-Herrscher Core. This gave Benares the ability to take on a human form, which Sirin named Bella (the same name as her best friend). Soon after, the Will of the Honkai pointed Sirin to the ruins on the moon.

Deep within these ruins, Sirin came face to face with "God".

Sirin was given a massive amount of information about the Previous Era and told about the Honkai's eternal crusade to eliminate humanity. The Will of the Honkai gave Sirin four Gems: the Gems of Conquest, Desire, Haste and Serenity. These Gems were portions of the next four Herrschers' abilities. In receiving them, she gained much more strength.

To test her newfound power, she flung some pillars from the temple onto the Earth. This caused massive destruction, killing millions.

Welt and Siegfried Kaslana launched themselves to the moon with the Arahato, where Welt engaged Sirin in battle again. Sirin stole Welt's Core from him and absorbed it into her body.

Sirin went back down to Earth and onto Siberia. Once she descended, she sent her Seraphim Princes, (each controlling Fire, Wind and Death in accordance with the Gems) to wreak havoc and destruction in Finland, Kazakhstan, and Russia (SFSR). Each of her minions was soundly defeated, which frustrated Sirin greatly. Bella had moved to engage Siegfried's formation while Otto Apocalypse, Fu Hua and Cheng Lixue engaged Sirin in combat.

Sirin fell into Fu Hua's illusion and was beaten there, allowing Otto to use his copy of Fenghuang Down to trick Sirin into resurrecting her dead mother. The outcome was not what Otto sought, since Sirin used the power of the Gem of Serenity to take DNA from her mother's apron, but also used the Core of Reason to re-create her mother's body instead of the Gem. Her mother was a soulless puppet and nothing more.

In his frustration, he had Sirin ask "God" what the meaning of a soul is. After asking his question, Otto was invited to meet with "God" and Sirin was freed from the illusion. Sirin re-engaged with Fu Hua in combat, causing the other to use her last resort (the Edge of Taixuan), which severed Sirin's link with the Honkai Will at the cost of Hua's memories. With an incapacitated Hua, Lixue willingly engaged in combat with Sirin in order to buy time for Otto to escape with her master, as Otto was temporarily unable to use Void Archives. After killing Lixue, Sirin corrupted a feather that Otto left behind from his Fenghuang Down mimicry. Sirin didn't waste any time testing out the feather and set her sights on Cecilia and Siegfried. The two were leading the formations responsible for holding back her swarms of Honkai Beasts, and their fall would help her chances greatly.

Sirin wished to create a nightmarish world where Siegfried and Cecilia would suffer and eventually break, but instead the dream world showed Siegfried and Cecilia living as a happy family, preparing for their daughter, Kiana Kaslana's, birthday. Her frustration finally reached its peak when she saw them celebrating. She ended up joining them in the dream world with the intention of destroying their happiness.

But she stopped when Cecilia told Siegfried off for not recognizing their "daughter" Sirin. She was invited inside and Cecilia gave her a slice of cake. Sirin took a bite and began crying, reminded of her dead mother and cake she would buy for her.

After going up to her room in the illusion, Cecilia joined Sirin and embraced her until she fell asleep.

On the next day, Sirin went shopping with Cecilia and Siegfried at the mall until Welt's interruption caused a large set of windows to burst near her. Cecilia jumped in front of Sirin to save her and suffered a cut on her cheek. Cecilia then told her "the magic words": Ich liebe dich (I love you).

Later that evening, Sirin was trying to figure out why Cecilia would jump to save her. The confusion from the most recent events began sewing doubt in her mind, but soon the Bella doll she was hugging disappeared as a result of Bella's Core being destroyed by Shub-Niggurath. This was thanks to a crack on her carapace left by the Judgement of Shamash in an earlier battle with Siegfried.

Losing her temper, Sirin ran Siegfried through with a Subspace Lance and was about to finish him with a second when Cecilia got him out of the way. Sirin, realizing that Cecilia knew that it was an illusion all along, flew into a rage, which allowed Welt to jump in and save the two.

Meanwhile, the Arahato had gotten into position to activate the Selene. Einstein activated it, which disrupted Sirin's Honkai energy enough to allow Siegfried and Cecilia to escape the illusion. They were reunited with Theresa in the real world.

Welt initiated his rematch against Sirin to stall for time, allowing Einstein a chance to try to neutralize the Honkai energy within Sirin. The Selene failed to do that, but Einstein was able to see the different Cores.

She began her operation to extract a Core from Sirin and got the Gem of Conquest out. She threw it to Tesla via the Arahato's right arm. She was about to attempt a second extraction when Sirin awoke. In her rage, she trashed the Arahato and crushed the Core of Reason.

Sirin was caught by a plant sprouted by the Abyss Flower, which prevented her from killing Einstein. Siegfried, Cecilia and Theresa now confronted her. Sirin's rage skyrocketed before she locked Siegfried and Cecilia into an Infinite Corridor, leaving Theresa to face Sirin on her own. Theresa activated the Oath of Judah's Zeroth Power to completely nullify Sirin's Honkai energy, and she reverted to being a powerless little girl within the field.

The field had affected Theresa's aim, so when she threw her spear, it landed in Sirin's right leg instead of her heart. The pain made Sirin remember the experiments, but a vision of Bella reminded her about her Gems and brought her back to her senses. Eventually Theresa closed the gap between them and stabbed Sirin in the heart. After Theresa removed the spear from Sirin, the Gem of Serenity revived her by repairing the damage.

Just as Sirin was about to deal the final blow to Theresa, Siegfried came bursting out of the Infinite Corridor cube because his MANTIS genes were activated, forcing him into a berserk state. Despite her best efforts, Sirin was easily defeated by Siegfried, her left arm being cut in the process. The berserk Siegfried ripped the Gem of Serenity out of Sirin as well as the other Infinite Corridor box that trapped Cecilia.

Shortly after, as Sirin's consciousness sank into the abyss, she came to the realization that she was alone and that she would die alone.

Almost as if in response to her realization, the damage that Sirin's Core received took its toll and it broke. The resulting break caused her Core to begin Cascading and bathing Siberia in pure, toxic Honkai Radiation that killed every living thing it touched.

Because Sirin no longer had control of her powers, the Infinite Corridor that held Cecilia collapsed and allowed her to escape. After tending to Siegfried and devising a plan, Cecilia moved to a vantage point. She commanded the Abyss Flower to take all of her Schariac blood and form a spear that would completely halt the abundance of Honkai energy erupting from Sirin's Core as well as cleanse Siberia of the radiation, healing those that were corrupted.

Siegfried dealt the finishing blow by charging the Judgement of Shamash (using the residual Honkai energy) and activating the Might of An-Utu. With a mighty swing he slammed the Might of An-Utu into the ground, causing a tremendous explosion and effectively nuking Sirin, completely halting the Core Cascade and nullifying her power.

Cecilia, now drained of her blood, went over to Siegfried and said goodbye to him, ordering the Abyss Flower to protect him because Otto had ordered Honkai fission missiles to be launched where Siegfried and Sirin were. Just as Sirin fell from the sky, Cecilia caught her, and the two of them spent their last moments alive together.

Several years later, Otto Apocalypse used Kiana's DNA to create clones in the hope of resurrecting the Herrscher of the Void in a suitable vessel. His plan was to control her afterwards. The clones from K-420 to K-422 had failed, and K-423, who had the Core of the Void implanted during her growth, had yet to gain awareness.

Otto was about to scrap the clone, but Sirin made a wish to start over as Cecilia's daughter, and the clone K-423 gained awareness shortly afterward. The implications of this have not been touched upon.


  • Sirin's name was previously localized as Celine. Likewise, Sirin: Ascendant was called Celine: Ascendant instead.
  • The name Sirin comes from Russian mythology. Sirin was a mythological being with the head and chest of a woman and the body of a bird. Men who heard her would forget everything, follow her, and eventually die.
