The woman was arrested, while Teru stealthily slipped away from the bustling crowd.

A hand alighted upon his shoulder.

"Thank you," Tomioka Giyu spoke, expressionless.

"Just to make sure the real culprit is justified." Teru dismissed the gratitude. "But why did you insist it was a demon who commited the crime?"

Giyu pondered if the man before him was an ordinary person ignorant of the existence of demons, asking out of curiosity or perhaps even mockery. He turned to depart, unwilling to divulge too much to an ordinary person.

"As a swordsman of the Demon Slayer Corps, do you believe demons commit more crimes, or is it humans who are inherently inclined toward evil acts?"

Giyu stood still, his gaze fixed on Teru with a sidelong glance. Who was this man?

"Demons are significantly outnumbered by humans, so it stands to reason that humans perpetrate more sins upon each other, wouldn't you agree?"

Since his youth, Giyu had clung to a belief that demons and humans were unquestionably adversaries, destined to be enemies, with only one capable of survival while the other faced extinction. But he had witnessed Nezuko, a demon who retained her sanity, and the cruelty humans inflicted upon each other. What recently happened had shaken his convictions. If killing demons to safeguard humanity was right, was it also right to kill humans to protect humanity, given that humans were capable of harming their own kind?

His brows furrowed as he lost himself in contemplation. When he looked up, the doctor he had been conversing with had disappeared.

Teru found his wife still seated in the carriage. With Muzan's keen hearing, she had, undoubtedly, overheard Teru's conversation with Giyu. How did he know about the existence of demons? Did he know that I was...? Her mind churned with turmoil, and she turned her head. In the next instant, a familiar, warm hand covered hers. She glimpsed her husband's smile, comforting and gentle as it always had been.

The narrative has been illicitly obtained; should you discover it on Amazon, report the violation.

That smile solaced her. Muzan then directed her gaze at Teru, her eyes unwavering, and she held it until the train had passed several stations.

When they disembarked, evening had approached . Teru held Muzan’s hand and deftly maneuvered through the crowd, protecting her from any inadvertent collisions, as always.

"I heard what you said."

"Yes."

"Let’s continue the discussion."

"Alright."

"What if demons feed on humans?" Muzan spoke softly.

"Hmm?" Teru tilted his head, as if he hadn’t heard what she said. Muzan lowered her gaze.

"Well, then it might be best to establish a medical institution under the pretense of medical research and procure an abundance of blood bags, so that they don’t have to kill people." Teru proposed.

"What if demons are malevolent?"

"Demons, like humans, come in both good and bad varieties, don't they? " Teru argued firmly.

"What if...a demon cannot endure sunlight?"

Teru turned to look. Muzan's eyes were reddened, on the verge of tears. She clenched her fists, her chest heaving, anxiously awaiting an answer. Suddenly, the light above them dimmed, nearly vanishing altogether. Teru had produced the large black umbrella he had used when visiting the source family, holding it over their heads.

"Then we'll simply have to create a massive umbrella to protect her."

Muzan laughed through her tears, playfully punching her husband's chest.

Her emotions were too intense, and therefore the punch was delivered with full strength. Realizing this, she hastily supported Teru, only to find him standing unharmed, completely composed.

"Are you alright?" Muzan gently touched Teru's chest, her concern evident.

"Absolutely!" Teru smiled, revealing his immaculate teeth.

The fact is, to appear strong before his wife, he swallowed down the blood that had risen to his throat.

Marrying a demon was indeed dangerous! Teru thought to himself.

Surprisingly, Teru crouched down and lifted Muzan all of a sudden. Amidst the dim light, they set off toward the Watanabe house, where they lived. Teru swiftly opened and closed the house door, entering Muzan's bedroom. He gently placed her on the bed and leaned in for a kiss.

But he was pushed away. Muzan burst into laughter again, and as she laughed, she began to cry.

Teru comforted her by stroking her back.

"This is wonderful; you've accepted me as I am."

"If I... what would you do?" Teru countered.

Then I'd have to find a demon whose blood demon art was about illusions and let it erase all your memories of demons, Muzan kept silent and thought to herself.

Teru interrupted her thoughts with a deep kiss. A nimble hand unbuttoned his shirt's collar.

He held her and went to the bathroom.
