Chapter 273: The Horror of Kiara
In the cyber-space transformed from the oil base, the youth searched for clues alone.
He hadn't expected the past of this alternate world, seen through his own eyes, to be such a shocking event. However, perhaps because he knew it was the fate of another version of himself, Shirou was able to accept it quite calmly.
Shirou held a conversation with BB, who was hiding within his mental world. By continuously traversing the data as a bystander, he witnessed everything that had occurred in the past.
"The black Senpai... he's completely broken, isn't he?" BB said, sighing with emotion.
"Yes. I didn't think such a world existed," Shirou replied softly.
"Shirou-senpai, you must cherish yourself. Don't turn into the type that is pitch black from the inside out," BB said, looking at Shirou with deep concern.
"I'll be careful. Regardless, I won't become that kind of person," Shirou nodded in agreement. That type of person was, if anything, the kind he disliked most. Taking it as a warning, he was confident he wouldn't become someone so "useless."
He discovered several records left behind by the employees of the oil field base. Aside from those who had been incited to fight and kill for power, he eventually found traces of a Demon God Pillar.
It seemed the Demon God Pillar Zepar had lost its will to fight in the Temple of Time. To repair its damaged body, it fled into the oil base, using the staff there as bait and food.
In this place, Zepar discovered a special existence: the oil base's psychiatrist, Kiara Sessyoin. From her, Zepar read the records of her parallel world counterpart—the one who became the Demonic Bodhisattva in the Moon Cell's cyber-world and manifested as a "Beast."
Thus, Zepar sealed away the "goodness" of the Kiara Sessyoin in this world and implanted the records of the alternate world version into her. It sought to recreate the Beast, thereby releasing an incredibly terrifying monster.
However, Zepar ended up digging its own grave. It went from controlling Kiara's status to becoming a dog deluded by her, until it was eventually discarded. It lost its consciousness and became a brainless Demon God Pillar with its eyeballs completely misaligned.
It feared Kiara and wanted to stay away from her, yet simultaneously feared being ignored by her.
To Kiara, who only viewed herself as a human and saw all other things in the world as insects, Zepar was merely a toy with a few extra tentacles. The Demon God Pillar released a monster it could not control, ultimately becoming a prop for Kiara to obtain pleasure.
"But the main issue now is Kiara Sessyoin. Even for me, that woman is an incredibly hated and dangerous individual," the purple-haired girl said, her brow furrowed in deep disgust.
"Kiara Sessyoin... if she is the opponent Gudako has to face, it seems far too dangerous. I must hurry there to protect her," Shirou said.
"Then we must investigate everything clearly now," the purple-haired girl added.
"Understood." Shirou held the diary and activated his Mystic Eyes, reading a certain connection linked to the alternate world.

Upon arriving in the electronic world constructed by the Moon Cell, the Servant Kiara Sessyoin summoned was Hans Christian Andersen—the author of her favorite childhood fairy tales, and an artistic Heroic Spirit who refused to perform manual labor or engage in combat.
Of course, Kiara, having understood the essence of this world, did not plan to fight from the beginning. While everyone else thought about winning the Holy Grail War to realize their wishes using the "All-Powerful Wish-Granting Machine," Kiara Sessyoin wanted to become the All-Powerful Wish-Granting Machine herself.
On one hand, she had harbored the desire to become a God since she was a child. From the moment she realized the truth that "humans do not save humans," her heart had become completely twisted. On the other hand, she craved to be the center of attention, sought after by all humans and Servants alike. That way, she could enjoy even greater pleasure.
To realize her greatest desire, she intended to seize total control of the Moon Cell from the inside, replace it, and become the world's only God.
Kiara's desire was limitless. A few million followers were not enough to satisfy her. If she became a God, she could receive the love of billions—the entirety of humanity. No, perhaps living humans weren't enough. It would be even more stimulating to make every Heroic Spirit in the Throne of Heroes fall in love with her.
To achieve this, she had to become a God first. Thus, to satisfy her desires and obtain greater ecstasy and pleasure, Kiara chose the path of apotheosis.
However, as an outsider, she was destined to be unable to hack directly into the Moon Cell's core to seize control. Therefore, she set her sights on the academy's high-level AI, Sakura. If she couldn't possess the authority herself, she would simply control the AI that held it.
Using All-Colored Stagnation (Manshoku-yuutai), Kiara caused a minor glitch—similar to a common cold—in the high-level AI, Sakura Matou, who worked in the school infirmary on the Near Side of the Moon. This activated Sakura's internal "self-consciousness" and disabled her "Self-Consciousness Suppression Program." Thus, an ordinary AI began to possess its own emotional consciousness.
"All-Colored Stagnation" was a spirit-focused technique Kiara had developed as a Spiritron Hacker during her life, possessing various miraculous effects. One of its primary functions was to make people forget all worries and pain, achieving complete liberation of the soul—a state of letting go of everything and reaching a state of "unearthly bliss."
It produced a trance-like state in the mind similar to the use of strong narcotics. If used frequently, one could never escape it. Its addictive nature was so extreme that the Western European Plutocracy listed it as the most serious taboo in computer history, leading to the global warrant for Kiara's arrest.
Those "poisoned" by it would fall in love with Kiara Sessyoin from the bottom of their hearts. Regardless of gender, they would become her followers, and all their pain would be redeemed. If the software was used by Kiara herself, she could transform someone into her believer at the very depths of their soul, making them a slave to her love and desire.
After setting this in motion, Kiara hid behind the scenes, quietly watching the development of events.

One day, in the academy on the Near Side of the Moon, the students lived their daily lives.
Issei Ryuudou, the student council president in his black uniform, stood at the school gate checking the students' attire. Hakuto, the girl with long chestnut hair, walked inside.
In the classroom, as the homeroom teacher, Taiga, walked in, she tripped. Her neck struck the corner of the podium, creating the sound of shifting and breaking bones as she lost consciousness...
After school, Shinji Matou became the center of the class, bragging amidst the praise of several students. He did have the right to boast; as the Asian gaming champion, he was one of the most capable individuals in the class.
The eight-year-old Shinji Matou in reality was slightly different from the one Shirou knew. He was a test-tube baby born from the preserved genetic material of the prestigious magus lineage, the Zolgen (Matou) family. A cocky brat, he was arrogant and constantly sought the limelight in class.
Everything around felt like déjà vu, as if it had happened before.
Hakuto arrived at the entrance of the school building, the foyer where students changed into indoor shoes. There, she saw a purple-haired girl in a white lab coat collapsed on the floor. The students passing by ignored her completely.
Hakuto stepped forward, used all her strength to pick up the girl, and brought her to the infirmary.
This was the beginning of everything.
The Super AI, which originally shouldn't have felt unnecessary sensations even while lying on the floor, developed feelings of loneliness and abandonment under the influence of "All-Colored Stagnation."
In a situation where everyone ignored her, Hakuto's act of finding and caring for her brought Sakura an unprecedented emotional shock. With Hakuto's gentle and considerate care, Sakura's nature as an AI began to shift toward "humanity." Her actions and thinking changed from those of a cold, expendable tool (whose data was deleted upon task completion) into those of an ordinary girl with warmth.
Thoughts like "I want to be with Senpai more" and "I want to talk to Senpai more" filled Sakura Matou's heart.
Realizing that the Holy Grail War was about to begin and that Hakuto would inevitably be involved, the purple-haired girl, out of concern, checked the Moon Cell's records for the first time out of selfishness.
According to the calculations, Hakuto—who seemed to have no special talents other than her kindness—would almost certainly lose the Holy Grail War. Even if she miraculously won, as an NPC, she would still disappear once she entered the Angra Mainyu (Throne of the Moon).
The outcome was destined to be one: whether she won or lost, as long as Hakuto participated in the Holy Grail War, she was doomed to vanish.
Unwilling to see such a future for Hakuto, the AI Sakura used all her Moon Cell authority to forcibly lock the time at the preliminary stage of the Holy Grail War, looping that single day for sixty-nine days.
During these sixty-nine days, Sakura repeated her encounter with Hakuto, and her affection for her Senpai grew deeper. But as this emotion sublimated from friendship and longing into a higher level, the AI Sakura reached her limit. She could no longer continue the loop.
Because her system could not comprehend the emotion called "Love," the AI Sakura fell into a logical paradox, leading to the risk of her data collapsing and vanishing. If she failed, the next existence to replace her as the infirmary AI would be Caren Ortensia. Sampling the daughter of the priest Kirei Kotomine from a certain city on Earth where a Holy Grail War had occurred, Caren's trait was to prioritize the completion of the Holy Grail War over assisting the participants.
If Caren took over, Hakuto-senpai would likely receive no help at all, making the possibility of victory even smaller.
To prevent this, the AI Sakura decided to seal all the memories of what had happened between her and Hakuto-senpai and return to being a normal health-care AI. However, Sakura did not have the authority to delete her own records. Therefore, she implanted those memories into her backup body. She cast it into the Far Side of the Moon—an area similar to a computer's "Recycle Bin," specifically used to store unnecessary and defective data.
This backup body was named "BB."
Because the AI Sakura had been affected by Kiara Sessyoin's technique, the virus that activated her self-consciousness and removed her suppression programs was also transferred to BB during the backup.
Kiara Sessyoin, lurking in the shadows, had originally planned to wait for Sakura's thought patterns to turn human, then control her with "All-Colored Stagnation" to gradually seize Moon Cell authority. However, seeing the interaction between Sakura and Hakuto was so interesting, she changed her mind and chose to continue observing.
After the sixty-nine days, she saw everything the AI Sakura had done. She then activated BB and injected the thought of "liberating the desires of all humanity." Thus, the most evil and cutest Super AI—BB-chan—was officially born.
Compared to the fragile AI Sakura, BB-chan's personality was much more stubborn. She hated her past self—the Sakura who could only hide in the infirmary. "Senpai! BB-chan will save you! Senpai's fate will be changed by BB-chan!"
Thus, she pulled Hakuto-senpai (from the stage between the end of the fifth war and the start of the sixth) into the Far Side of the Moon.
BB obtained the authority of the primordial goddess "Potnia Theron" (Mother of All Beasts) from the Moon Cell. With the ability to create all things, she manufactured the five members of the Sakura Five. Among them, Meltryllis (Lilith) and Passionlip (Lip) were summoned to help her block her Senpai.
Using her characteristics of Imaginary Number Space, she turned herself into "Infinity," remodeled the Far Side of the Moon, and built the Old School Building for the Masters to live in. She continuously dug a tunnel to find a way to break through the protective wall of the Moon Cell's core—and this tunnel became the Sakura Labyrinth.
While BB was blocking her beloved Senpai from returning to the Near Side to participate in the Holy Grail War, she was also searching for a breakthrough to gain the Moon Cell core authority.

Kiara Sessyoin first absorbed Passionlip. After that, she used "All-Colored Stagnation" to make Lip's shell a body double for when Meltryllis tried to assassinate her, eventually absorbing Meltryllis into her body as well.
Then, when Hakuto successfully entered the Moon Cell core and caused BB's defenses to slacken, Kiara gradually absorbed the goddess authorities of the several Sakura-series AIs, including Sakura Matou herself, and transformed into a new Earth Mother Goddess.
As a result, the horns of Mara grew from Kiara Sessyoin's head, and she donned a glamorous haori.
Her image was like the enemy of Buddha, the ruler of the Sixth Heaven of the Desire Realm, Mara Papiyas. A "Beast" (Humanity's Evil)—manifested here. A Demonic Bodhisattva, more powerful and terrifying than BB, appeared in this world.
She prepared to use the power of the Moon Cell to liberate the desires of all humanity, letting every human be immersed in love and lust. Ultimately, this would bring her the supreme pleasure that no one had ever experienced: the moment of total human extinction.
"Ahaaaaaa! This feeling is truly the best! Ah! Ah! AH!"
After obtaining the authority of the Moon Cell, the first thing Kiara chose to do for herself was to simulate and experience all kinds of pleasure.
For instance, the pleasure of reaching a climax simultaneously across countless parallel worlds. For instance, the pleasure of being killed repeatedly every second. For instance, the pleasure of destroying world after world and feeling the moment humans collapse in despair.
