It was not a remarkable door: well-polished wood, no unnecessary ornamentation, simple but sturdy. It suited perfectly the person who lived beyond it.

Tengen had faced high-ranking demons, made decisions that put human lives at risk without flinching, and even stepped into battle wearing a confident smile when the odds were stacked against him. And yet, that night, there was a strange weight pressing against his chest—as if something, an intuition perhaps, warned him that crossing that doorway would mean dragging someone else into a fate he could not guarantee.

He thought of Hinatsuru. Of Makio. Of Suma. Of the messages that had arrived too late, of the prolonged silences and carefully measured phrases from women who always found a way to say more; of the doubt that had been gnawing at his nerves for days.

The Entertainment District was not a place that swallowed people whole. It wore them down at its own pace, made them disappear without anyone being able to point out the exact moment it happened.

There was no one else he could turn to.

Shinobu was far away, tied to a mission she could not abandon. The same happened with Mitsuri, dispatched to a location too exposed to recall her without raising suspicion.

Tengen had considered other names, but none of them fit.
Too clumsy. Too conspicuous in all the wrong ways. Too fragile.

He exhaled slowly, adjusting the bandages around his forearms as if reminding himself that he was still the same man he had always been. The Sound Hashira. The flamboyant one. The one who never hesitated.

He knocked.

The door opened almost immediately, and Kyojuro appeared—wearing a broad, open smile, dressed in comfortable clothes, his hair loose and falling in unruly strands over his shoulders.

“Uzui!” Kyojuro’s voice rang out with his usual, unmistakable energy. “What a surprise! I wasn’t expecting visitors at this hour.”

The Sound Hashira smiled wide and confident, as though he hadn’t spent the last few minutes locked in an internal debate.

“And isn’t that the best for such a boring night?” he replied lightly. “Being surprised by such a flashy presence!”

Kyojuro stepped aside, and Tengen accepted the invitation.

The door slid shut behind him, and the warmth of the entryway made him shiver pleasantly in contrast to the harsh night cold he’d left outside.

Kyojuro was barefoot. His haori rested over the back of a chair with his sword laid carefully beside it.

They sat across from one another, steam rising between them as Kyojuro poured the tea.

“So,” he said, “how has duty been treating you lately?”

Tengen parted his lips—but no sound came out at first. He hesitated, and of course, it didn’t go unnoticed. Kyojuro raised an eyebrow.

“That’s unlike you,” he added. “When something troubles you, you usually say it outright.”

Uzui laughed softly.

Sharp, as ever.

“I was just choosing the right words,” he said, taking a breath. “My wives are infiltrated in the Entertainment District. I suspect high-ranking demons are hiding there. Demons skilled at blending in among humans.”

Rengoku nodded, his expression growing heavier. The mere mention of such creatures was enough to put anyone on edge.

“Have they stopped communicating with you?”

Tengen clenched his jaw in response, pressing his hands together in his lap. His nails dug into his skin until his knuckles turned pale—an outlet for the frustration he had been carrying for weeks.

“I need backup,” he continued. “But I can’t rely on just anyone.”

The Flame Hashira met his gaze, attentive, waiting.

“Why me?”

Tengen held his eyes.

“Because you’re strong,” he said. “And because you’ve always known how to adapt.”

Kyojuro frowned slightly.

“Explain.”

“I need you to infiltrate the district.”

There was no proper way to say it. Or at least, that was what Tengen believed. Honesty seemed easier—laying all his cards on the table. He had no other option. Especially with time working against him. And against his wives.

The words lingered in the air between them.

Kyojuro did not answer right away. He lowered his gaze, thoughtful. His hands rested firmly on the table, not tense, but grounded. Several seconds passed before he looked up again.

“That’s… a different kind of exposure,” he said calmly.

Tengen nodded.

It wasn’t merely physical danger—it was visibility. Allowing one’s body and image to be scrutinized by complete strangers.

“That’s why this isn’t an order,” Tengen replied. “If you refuse, I’ll find another way.”

Kyojuro closed his eyes for just a moment.

Images came unbidden: the people trapped there, demons feeding on desire and desperation… the possibility of protecting everyone living within the district.

“I need to know something,” he said at last. “If I accept—will I have constant support?”

Tengen answered without hesitation.

“I’ll stay close,” he promised, both corners of his mouth curving into a proud smile. “Closer than I probably should. Anything less would be unforgivably tasteless.”

“And if, at some point, I decide I can’t continue?”

Another clear answer:

“I’ll get you out. No questions asked.”

Silence fell again, and for Tengen, time seemed to freeze while the other man weighed a decision that felt final.

“Then I accept.”

The former shinobi stared at him—surprised… and relieved.

They left the following day.

Tengen dressed discreetly, though even then it was difficult to hide his presence: dark colors, minimal jewelry, weapons carefully concealed. Kyojuro, for his part, wore plain clothing suited to an ordinary traveler. Without his uniform, without his haori, he looked younger—and strangely vulnerable.

The Entertainment District greeted them with an explosion of color, with hanging lights that never seemed to go out, music spilling from every alleyway, heavy perfumes mingling with tobacco smoke and the constant murmur of voices. Tengen walked with ease, guiding him, alert to every detail.

“Here, every gesture matters,” he explained quietly. “The way you walk. The way you look.”

Kyojuro observed everything attentively, without judgment, trying to absorb as much as possible during his first contact with such place.

The house Tengen had chosen was not ostentatious—and that alone made it unusual.

It sat on a side street, close enough to the heart of the district to avoid suspicion, yet far enough away to allow a measure of calm as the night wore on.

From the outside, it looked modest: a discreet façade, well-kept sliding doors. Nothing eye-catching. Nothing that screamed Hashira.

Tengen slid the door open naturally and gestured for his companion to enter first.

The interior was small, but functional: two main rooms divided by folding screens, a pair of futons already laid out, a low table with basic utensils, and a window facing the street—shielded by wooden latticework that allowed one to observe without being seen.

Naturally, Tengen had prepared everything in advance: discreet seals, hidden weapons within arm’s reach as well as escape routes planned down to the smallest detail.

“Here, the less you stand out, the better,” he said, noticing the way Kyojuro studied the room. “Luxury draws unnecessary attention.”

The blond removed his sandals and stepped further inside, surveying the space calmly, as if committing it to memory. Tengen watched him in silence. Even without his uniform, Kyojuro carried a presence that was difficult to ignore—not because of extravagance, but because of conviction. That unique way of inhabiting the world with honesty.

“You’ll stay here tonight,” Tengen said. “I don’t want us rushing things.”

Kyojuro tilted his head.

“I appreciate the consideration,” he replied. “I know this isn’t easy for you either.”

Uzui clicked his tongue, dismissing it with a vague wave of his hand.

“I’ve dealt with worse.”

It wasn’t entirely true—or at least not with this kind of uncertainty—but Kyojuro didn’t contradict him.

Night fell quickly over the district.

From inside the house, the sounds of the Entertainment District reached them muffled: distant music, laughter, hurried footsteps, voices intertwining like a constant tide. It was a world that never slept, never let its guard down—even in the shadows.

Kyojuro sat near the window, watching through the lattice.

“It’s so… different,” he murmured.

Tengen leaned against the opposite wall.

“That’s what makes it dangerous,” he said. “Here, even violence smiles at you.”

They shared a simple dinner. They spoke little—not out of discomfort, but because both seemed aware that they were suspended in a brief pause; a grasp of air before something far larger and unknown fell upon them.

Though Kyojuro appeared calm, Tengen—trained to notice details—caught the tension held in his shoulders, the deliberate care he took with every movement.

When it was time to retreat into darkness, the taller man gestured toward the futon.

“Rest,” he said. “Tomorrow will be a long day.”

Kyojuro nodded.

“Uzui,” he called before lying down. Tengen looked up. “It’ll be fine,” he said sincerely.

But Kyojuro had no idea how wrong he was.
