The planet-star Houkai beast guided by the will of the Houkai. Destroyed human civilization in the Era: ZERO, but also agreed with Kiana to maintain and protect the stigmata terminal.
Jyahnar sees humans as ants, but under the influence of Kiana, she also became interested in this little race.

Era: ZERO[]
From the Anti-Entropy Agency report, this Planet-class Houkai beast was born in the Centaurus A, first observed on May 9, 2038. It has a diameter of about 4000 kilometers, the size of Australia, and its moving speed is close to the speed of light. It was known for devouring planets and the next target was the planet Earth.
Before that, it was identified as a small meteorite because of extremely small size and was not taken seriously. A year ago before being observed, it was 238 times smaller.
As a Planet-class Houkai beast, Jyahnar defeated the defensive weapon "God of War" in the orbit of the Earth and destroyed human civilization. At Kiana's request, she left the Stigmata System and continued to serve its energy supply.
Sangharama Fantasy Sea[]
42000 years later, Anti-Entropy came to the ancient ruins in the deep sea under a small island based on the deciphered text. At the same moment, Schicksal also acted.
After receiving the shipwreck report, Schicksal's Far East Branch found the Moonlight Throne near the island through satellite images. While speculating on the cause of the enemy's movements, the Far East Branch decided to send Theresa to investigate. At the same time, Kiana also participated in this operation and went to this destination with Theresa and Himeko.
But the three of them didn't investigate the area together as originally planned. Unconvinced Kiana argued with Himeko and was left alone. Kiana, acting alone, met a young girl there. The girl's origins are mysterious. When she reported her home, she only explained that someone called her "Cthulhu" and that she claimed to be a human being. However, in Kiana's eyes, she is nothing more than an ordinary person who lost her memory in the shipwreck.
In fact, the form of "Jyahnar" in Kiana's eyes is not the deity. Her true posture is more unrestrained than it is now. But no matter how she hinted, Kiana didn't doubt her and even wanted to protect her, which made Jyahnar even more interested in Kiana.
Kiana finally met Theresa and Himeko, she thought Theresa could be at ease, but Theresa pointed out that Jyahnar has a powerful Houkai ability like a Herrscher. Faced with the attacks of the two, Jyahnar showed her true power and started a battle with everyone.
However, Jyahnar's power wasn't as strong as she had imagined. With her current power, it was no longer possible to destroy humanity. As a compromise, and because of Kiana, Jyahnar decided to believe in human possibilities for the time being. At the same time, she also uttered a very misleading word to Kiana:
"I love you, Kiana"
Otherworld - Explorer[]
When the enthusiastic Jyahnar returned to the bottom of the sea, she met the Anti-Entropy Enforcer Yssring Leavtruth and the elite Bronya team who came to explore the ruins of Sangharama, but Jyahnar wasn't interested in them as she used to meet old friends as a reason.
The Doctor followed Jyahnar for the truth, but it didn't take long for them to be discovered by Jyahnar. The Doctor desperately wanted to ask for all this information from her, but for Jyahnar, everyone who came here asked the same question, which was too boring and thoughtless, Jyahnar answering the Doctor and directly started the battle. At the very moment, the Houkai Strategic Integration Terminal awakened and blocked Jyahnar's offensive. Everyone also took the opportunity to escape.
Phantom Sea Abyss[]
Sangharama is an ancient defensive city. Long ago, Kiana met Jyahnar here, and the Doctor discovered the War God on the seabed—and now, Schicksal and the Anti-Entropy are fighting, here again, to sink the seabed belonging to the real secret of Sangharama.
Under the main artillery bombardment of the Brilliant Covenant, the island was blown out of a big hole as a gap for entry, and Otto also began to enter Sangharama. In the counterattack, Kiana and her team rushed to the island, but they were attacked by Maria. It's just that because of Maria's strength, Kiana can't do anything, and the Moonlight Throne is constantly facing the impact of the Valkyrie troops, which is in danger. At this moment, the tentacles suddenly appeared and hit both sides.

Phantom Sea Abyss CG
And because of this, Jyahnar, who went to slaughter the Valkyrie, after a battle with Maria and others, Jyahnar finally thought that her attempt to accept humans had failed, the ant-like humans are not worthy of her attention. What she has to do is to pick up the mission of destroying humans - so Jyahnar finally showed her true form in front of everyone...
Long before Jyahnar appeared on the island, she met the Doctor on the seafloor. The Doctor who planned to dive deep to enter Sangharama was discovered by Jyahnar during the research. Fortunately, the Brilliant Covenant artillery attack diverted Jyahnar's hatred, the Doctor and Bronya escaped safely and entered Sangharama.
The Doctor stood in front of the gate, trying to open it, but under the defense of that special metal, even Kika's Nexus system couldn't open it. So Kika tried to cooperate with the Doctor to open the door and told her the truth about the Stigmata Project. The Doctor who knew the truth thought that opening the door was opening Pandora's box that would destroy the future of mankind, and refused to help. The two were entangled but were forced to leave when Jyahnar regained consciousness. Although Yssring learned about the Stigmata Project from Otto, the Doctor still stopped in front of the truth about Sangharama-
Back on the battlefield, Jyahnar finally revealed her true form, the whole island is her body. To stop Jyahnar, Kiana stepped forward, even Maria was shocked by her Cecilia-like temperament. She made an exception and let Kiana go to fight with Jyahnar.
Jyahnar, who had restored her original body, abandoned the appearance of a human. As mentioned above, Kiana, who appeared in front of Jyahnar again more than 40000 years later, has long since disappeared from the shadow of that time and has become like a human. And Kiana also began to have doubts because of Jyahnar's words, her identity, and what she wanted to express. And Jyahnar also began to look forward to it, expecting Kiana to remember who she is, and stay at Jyahnar for this.
Dream of the Sea[]
The decisive battle between the Planet-class Houkai beast and Schicksal finally arrived. Otto led all his power to attack Jyahnar. In the battle, Jyahnar, who had lost patience with humans, showed brutal dominance. Although Cocolia's Titan troops greatly supplemented the damage for Schicksal, Jyahnar split out countless neuronal mimicry her own, and soon made Schicksal into a bitter battle. As the scene gradually fell, Kiana finally rushed to the battlefield and used the power of the saint to help Schicksal to suppress the power of Jyahnar. Jyahnar believed that she would never understand humanity and invited Kiana to destroy the world with her.
On the other hand, Yssring and Bronya took advantage of Schicksal to hold back Sangharama's outer defense line and sneaked into Sangharama under the sea again. Under the exploration of Armored Bunny 19C, the group went deep into the hinterland that they had never been before. There, according to the changes in the environment, Yssring inferred an astonishing fact - the entire island is the body of the Planet-class Houkai beast, and Sangharama is located in her abdominal cavity. Ninti quietly followed the Doctor and the team into Jyahnar's body. After being discovered, she fought with the Anti-Entropy trio. Yssring went to the laboratory where the Stigmata Terminal was hidden and found that the badge given by the traveler was the key. When Jyahnar's clone appeared, Yssring asked Jyahnar why he wanted to protect the Stigmata Terminal, but Jyahnar didn't answer.

Angelia Schariac death scene
After Maria was severely injured, Jyahnar revealed her huge Houkai beast body. Jyahnar reappeared, saying that the "Power of the Saint" belongs to Kiana of Era ZERO, and she is ready to take back the power. Angelia blocked the fatal blow for her sister Maria, and her vital signs disappeared.
Seeing that Schicksal was nearly collapsed under the ravages of Jyahnar, Otto finally revealed his trump card - he installed a transmitter on Ninti, and when Ninti was positioned at the core of Jyahnar, Otto gave an order. Next, Flora launched the Brilliant Covenant's main artillery and shot at the core. The Planet-class Houkai beast was severely damaged and fell back into the sea. The Doctor didn't want Ninti to sacrifice and open the laboratory with the traveler's badge, preparing to resist artillery fire from Brilliant Covenant. Ninti took the badge to complete the task Otto gave her. Jyahnar guided Kiana and her team to the laboratory where the doctor was located and found that the Jyahnar's Core was attached to the Stigmata Terminal. Only then did Jyahnar reveal to them the truth of the Era Zero Kiana. A request was made to Jyahnar, hoping that she could provide the last trace of energy for the Stigmata Terminal, and Jyahnar agreed without hesitation to place her core on the stigmata terminal.

Jyahnar ending scene
Jyahnar asked Kiana to destroy her. After the destruction, Jyahnar used the last remaining strength to shape a human body, expressing her longing for thousands of years.
When Houkai created her, in addition to genetically engraving the mission of exterminating mankind like other Houkai creatures, it also included other information. That is to let her come to this planet to find the trace of Kiana and to destroy humanity together with Kiana as the Messenger of the Houkai.
At the end of her life, Jyahnar hopes to become a human in the next life. Kiana didn't want Jyahnar to die like this and used the power of the saint to completely integrate the core into Jyahnar's human body. Jyahnar survived but fell into a deep sleep.
