After two days of rest, Seiran's body felt restored. The sluggishness that had plagued him was gone, replaced by a familiar sharpness. He had a target now, and it was time to move.
Finding Orochimaru wouldn't be easy. The man was a ghost—always hidden, always scheming. His laboratories scattered across the Hidden Leaf Village's underside like a disease. But Seiran had cultivated insurance for exactly this situation.
Anko Mitarashi.
The relationship he'd built with her over months hadn't been sentimental. It was tactical. A bridge to the one man in the village whose intellect rivaled his own ambitions. Now, that bridge would be crossed.
The knock on Anko's door came firm and deliberate.
She opened it to find Seiran standing in the afternoon light, and her eyes widened in genuine surprise.
"Seiran! You're back? The mission—"
"Completed," he said with a practiced smile. "Two days ago. I need your help with something."
Anko had changed noticeably. Her biomagnetic field pulsed stronger than before, her chakra reserves visibly expanded. Orochimaru was investing in her properly. That was good information.
"I need to find Orochimaru," Seiran said directly. "Can you take me to him?"
She hesitated only briefly. "He should be at the experimental base. I can show you, but..." She lowered her voice. "He doesn't like being interrupted there."
The fact that she took him anyway spoke volumes about her regard for him. Seiran filed that away.

The sewer beneath the village was a different world—damp, suffocating, water dripping from rusted pipes in a rhythm like a dying heartbeat. Their footsteps echoed off stone walls slick with moisture and decay.
"Are you certain about this?" Seiran asked, pulling his collar up against the chill. "Orochimaru operates down here?"
"Most of the time," Anko confirmed, moving deeper into the darkness. "Though he gets angry when I track him down."
Seiran understood. In his former life, this very sewer had been where the Third Hokage discovered Orochimaru's human experimentation facility. One of many hideouts. Hopefully, the worst experiments hadn't begun yet. Hopefully, there was still time.
The tunnel opened suddenly into a vast chamber flooded with harsh white light.
Rows of wooden shelves stretched across every wall, lined with glass containers. Inside them: tissues, organs, cells suspended in various solutions. Biological samples that made the laboratory feel less like a workspace and more like a tomb.
Orochimaru stood at a microscope, his back rigid, completely absorbed in his work.
"Anko," he said without turning, his voice like gravel being dragged across glass, "I told you not to come here unless it was urgent."
Anko glanced at Seiran uncertainly. "It's Seiran who wanted to see you."
Orochimaru's entire body tensed. He turned slowly, and when his eyes found Seiran, something between a smile and a predator's grin spread across his face.
"Seiran. How... convenient. I was so absorbed in my work, I didn't notice your arrival."
"What consumes your attention so completely?" Seiran asked, moving deeper into the laboratory. He kept his tone light, casual. "It must be fascinating."
Orochimaru's pupils dilated with an almost manic enthusiasm. "A cellular comparison unlike anything I've encountered. Two extraordinary samples." He gestured at the microscope. "One exhibits superhuman vitality—cells that continue dividing rapidly even decades after extraction. The other..." He paused, savoring the description. "Superior cellular efficiency, extended lifespan, energy conversion rates that defy conventional biology."
Seiran felt the weight of his gaze settle on him. He'd made the right choice waiting two days. Orochimaru's hunger was visible in the tremor of his hands.
"Anko," Orochimaru said smoothly, "rest. I have matters to discuss with Seiran alone."
She nodded and left without complaint. As her footsteps faded, Orochimaru's expression shifted—less controlled, more feral.
Seiran redirected immediately. "You mentioned the cellular comparison. What exactly are you studying?"
Orochimaru let out a rasping laugh. "The cells of Hashirama Senju—the First Hokage. I possess samples. But the second..." He turned back to the microscope, lost in rapture. "Its vitality doesn't match Hashirama's raw power, yet its efficiency surpasses it dramatically. The cellular activity, energy conversion—it's superior in every measurable way. Hashirama's cells are crude by comparison."
Seiran understood. The monster scientist was attempting to decode something fundamental about his nature.
"You believed it was atavism initially," Orochimaru continued, his voice trembling with intellectual ecstasy. "But now I understand. You're the first dual-bloodline successor in Hyuga history for a reason. The change began at the embryonic stage—a genetic mutation that persisted, adapted as you developed. An accident of birth that became your greatest asset."
"I see," Seiran replied, mind already three moves ahead.
Orochimaru was theorizing, building narratives within the constraints of his knowledge. He was brilliant, yes. But his brilliance was bounded by the shinobi world's understanding of cellular biology. Electromagnetic induction, the deeper mechanics of biological systems—these remained mysteries to him.
Let him theorize. Theory was safer than truth.
"Orochimaru," Seiran said, "I came here hoping to ask you something. I need access to your laboratory."
The scientist's eyes narrowed with calculating interest. "My laboratory? For what purpose?"
"Research," Seiran said simply. "The same thing you're doing. I need to understand myself."
A long pause stretched between them.
Orochimaru began to laugh—a sound like wind through a grave. "A caged bird finally learning to sing. I didn't expect you to seek me out, but it's... appropriate. We both want something. We both have needs that align."
His gaze swept across the laboratory's shadowed corners, where specimens waited in suspension.
"There's much we could accomplish together, Seiran. The Hyuga elders have their rules, their restrictions. But I?" He smiled, and there was nothing human in it. "I have no such limitations. For the pursuit of truth—for immortality itself—I would sacrifice anything."
Seiran met his gaze steadily, letting him believe what he needed to believe.
"Then we have an understanding."
