Walking along the riverbank, Kurogiri Senga felt a profound heaviness in her heart. As to why it weighed so heavily, she couldn't quite articulate it; there was just a deep, sinking feeling, draining all motivation.

Strolling on, her foot suddenly slipped. Senga gasped, unable to regain her balance in time, and with a loud splash, she tumbled entirely into the river.

"Aargh... what in the world is happening?!" The river wasn't deep, only reaching her waist, but even so, Senga was now utterly drenched. As she stood up, she couldn't help but complain, but her look of annoyance quickly morphed into sheer terror, for she suddenly realized that her chest—which, while perhaps not extravagant, was certainly noticeable—was now as flat as a tabletop... gone! Completely vanished!

Senga's face immediately paled as she clutched her completely uncurved chest, a cold dread washing over her.

Just then, the water before her erupted in a dazzling golden light. Within that radiance, a bunny girl slowly rose from the river, cradling two shimmering golden orbs.

"Y-You... who are you?" Senga was startled and instinctively asked.

"I am the Rabbit Goddess who governs the breasts, residing in this river. You may call me Nyū-shin," the bunny girl stated, radiating a light too intense to look at directly.

"The B-Bunny Goddess?"

"Precisely." Nyū-shin nodded, then inquired, "Did you happen to lose something in this river just now?"

"Uh, well... my breasts are missing," Senga admitted with considerable shyness.

"I see. Then, are you missing this Grade A bosom, or this Grade D bosom?" Nyū-shin offered the two golden spheres in her hands toward Senga.

Senga was nearly blinded by the glare. Gazing at the colossal Grade D mounds, she involuntarily swallowed, but knowing honesty was crucial in this narrative, she suppressed her sudden impulse and pointed to the Grade A set. "This one. It was mine."

Nyū-shin glanced at her, then sighed. "This Goddess favors those who strive and seize opportunity. Yet, you cling to your own flatness, ignoring the bounty within easy reach. You disappoint this Goddess greatly. In that case, you shall live out your life with this flat form."

With that, Nyū-shin turned, preparing to depart.

Damn it! This isn't how the script goes!

Senga was on the verge of a breakdown and quickly called out, "Wait! Mine was Grade D!"

Hearing this, Nyū-shin turned back. In that instant, cicadas wept and sea cats cried mournfully; she roared with a terrifying visage, as if possessed by Rina Inuzaki, "You lied!!!"

"Wait! Don't go! Don't leave, Nyū-shin! Give them back to me... Return my breasts to me!" Senga burst into tears, collapsing in the river, crying out in despair towards the already vanishing Goddess.

"Senga... Senga! Senga, wake up."

At that moment, she heard a familiar voice right beside her ear. She snapped her eyes open to see Shiki Ryougi, the woman she disliked most in the world, sitting opposite her, gently shaking her shoulder. Looking around, there was no Bunny Goddess, no river—only a train carriage.

Senga immediately snapped back to reality. Instinctively, she reached for her chest. Discovering her breasts hadn't vanished, she finally let out a sigh of relief.

It was just a dream... Senga secretly felt fortunate.

"What's wrong? Did you have a nightmare?" Shiki Ryougi asked.

"No way!" Senga retorted, blushing deeply.

"You don't look well. You must not have slept all night; you fell asleep as soon as you got on the train... By the way, we've arrived in Fuyuki City now. We don't know when the enemy will attack, so I suggest you calm down quickly," Shiki said with a hint of concern.

"None of your business!" Senga replied stubbornly, then snorted coldly and stepped off the train.

Shiki shrugged, wearing a thoroughly perplexed expression.

"Indeed, this city is shrouded in an ominous aura," Aozaki Touko remarked grimly after everyone had disembarked, taking a drag from her cigarette and sensing the city's energetic fluctuations.

"Who cares? I fear nothing now; even a god cannot stop me!" Senga's face held an expression of resolute sacrifice as she heavily stomped her foot onto the station floor. With a boom, dust and aura danced together in that instant.

While it looked imposing, stomping the floor is a classic death flag, isn't it? If she hadn't stomped, she wouldn't die—why can't anyone understand that?

...

At almost the exact same moment, on the opposite end of the Fuyuki Subway Station, Akiha Tohno arrived in this city, soon to be teeming with monsters, accompanied by her two personal maids, Kohaku and Hisui.

"Kohaku, have you booked the hotel?" Akiha Tohno inquired immediately after stepping off the train.

"Yes, Little Miss Akiha. The most luxurious hotel in Fuyuki City was contacted and secured last night," Kohaku replied respectfully.

"Good, let's go." Akiha Tohno nodded and stepped forward.

Truthfully, Akiha Tohno sought nothing from the Holy Grail. As the head of the largest Zaibatsu family in Japan, possessing the bloodline of a Demon God, she lacked nothing in terms of wealth, power, or strength. To exaggerate, if she desired the stars from the sky, someone would surely pick them down and deliver them to her.

However, as a human, she inevitably possessed human emotions and desires—things even her power and influence couldn't attain, such as... the truth behind the death of her father, Tohno Shingyoku, ten years prior.

The information she received was that her father was unexpectedly murdered while escorting the last two surviving bloodlines of the Kiri-ju clan back. She had absolutely no clue about the motive or the identity of the killer.

Over the past decade, through her increasingly deep involvement with the hidden darkness of this world, she had gradually come to understand what kind of family the Tohno clan truly was, the nature of the Kiri-ju clan—one of the Four Great Exorcist Families—and the real reason her father adopted Kohaku and Hisui... Even if she didn't dwell on it seriously, she could grasp the true purpose beneath that act of kindness.

But no matter what kind of man Tohno Shingyoku was, he was still her father.

Even if her father initially adopted Kohaku and Hisui with ulterior motives, he never got the chance to act on them. Conversely, for Kohaku and Hisui, they were truly rescued from the mire of despair, able to survive securely under the great tree that was the Tohno family.

As the saying goes, an innocent man is doomed by his wealth. Kohaku and Hisui, as the last two bloodlines of the Kiri-ju clan, were treasures to many in the hidden world. At around six years old, with their family ruined and themselves physically defenseless, it was easy to imagine the horrific fate that awaited them without Tohno Shingyoku's adoption.

From this perspective, Tohno Shingyoku, though a scumbag, did one good deed. Even in the original timeline, his actions weren't entirely beyond the pale of human depravity. Of course, one thing is one thing: even if he provided stability for two six-year-old girls, indulging his lust upon them forever
