Human with Senjutsu

Rias Gremory paced back and forth in her clubroom, her thoughts racing. The events at the church had been nothing short of extraordinary, and she couldn't shake the image of the young man, Itachi Uchiha, from her mind.

"A human," she murmured, staring out the window, "capable of wielding Senjutsu—and at such a masterful level..."

Sona Sitri, her closest friend and fellow devil heiress, adjusted her glasses thoughtfully. "It's not just his use of Senjutsu that's unsettling. His precision, his aura, and his demeanor—it was like he was trained for this kind of conflict. But humans don't—shouldn't—have access to this kind of power, at least not without... complications."

Koneko Toujou sat nearby, unusually quiet. Her small frame trembled slightly, her fists clenched on her lap. She had been unusually tense since their return from the church, and it was clear something was on her mind.

Finally, Koneko spoke, her voice steady but laced with unease. "That boy... the smell."

Rias and Sona both turned to her, surprised. "What do you mean?" Rias asked.

"The chocolate box," Koneko replied, her amber eyes narrowing. "The one I received the other day—the one with that strange letter. It had the same scent as him. I didn't realize it at the time because of everything else happening, but now..." She trailed off, her fists clenching tighter.

Rias frowned. "You think he sent it?"

Koneko hesitated. "Yes."

Sona's expression darkened. "If he knows enough to send you such information, he might know far more than we're comfortable with. I'm sure he isn't just some rogue human with an unusual gift."

Before Rias could respond, Koneko abruptly stood, her aura flaring around her. "I'm going to see him," she said firmly.

"Koneko, wait!" Rias called, but it was too late. The white-haired girl bolted from the room, her speed making her difficult to follow.

Rias sighed heavily and turned to Akeno, who had been silently observing. "Get the rest of the peerage. We need to stop her before this escalates."

Itachi's Home

Itachi sat at his modest dining table, the soft glow of a single lamp illuminating his meal. The boiled egg in his hand was perfectly cooked, and he ate with a calm that belied the chaos he had left behind at the church.

A notification blinked on his system window about 85,000 Shock Points he had earned by showing his face to the main characters.

A faint smile crossed his lips. This world really does react dramatically. Good.

As he prepared to take another bite, he sensed a presence approaching—fast. His dark eyes flicked to the window just as it shattered in an explosion of glass and energy. A white-haired girl with cat-like ears and a fierce aura stood in the frame, her fists glowing with Senjutsu energy—or, in other words, chakra.

Itachi placed the egg down gently and stood, his expression neutral. "You could've knocked."

Koneko didn't reply. Instead, she launched herself at him, her movements a blur. Itachi sidestepped her first attack with ease, his Sharingan whirring to life as he analyzed her movements. When she came at him again, he caught her fist with precision and countered with a powerful punch to her stomach, sending her flying back out through the broken window.

The impact shook the ground outside, leaving a stunned Koneko lying amidst the debris.

Rias and her peerage arrived moments later, just as Koneko struggled to her feet. Rage bubbled within Rias as she saw the state of her servant.

"Itachi Uchiha!" Rias called, her voice echoing. "How dare you harm my servant?!"

Itachi stepped outside, his movements calm and deliberate. His crimson eyes locked onto Rias, and he raised an eyebrow. "She attacked first," he replied evenly. "I merely defended myself."

"That's no excuse!" Rias snapped, her crimson aura flaring. "You have no right to harm her, after the letter you sent to her."

Itachi crossed his arms, unbothered by her anger, completely ignoring them.

"How can you hurt her? She only wanted answers," Issei Hyoudou, Rias's pawn, stepped forward, his Boosted Gear materializing on his arm. "Don't you think you should apologize to her?"

Itachi's gaze shifted to Issei, and the young devil froze in place as the three-tomoe Sharingan seemed to pierce his very soul. "Stay out of this," Itachi said coldly.

Rias clenched her fists, her aura intensifying. "Enough! You owe us answers. Who are you? How can a human like you wield Senjutsu? And what do you want with us?"

Itachi regarded her for a moment, then sighed. "You're asking the wrong questions. But since you're so insistent..." He stepped forward, his presence commanding. "My name is Itachi Uchiha. I have no interest in your petty power struggles or your factions. I'm here for my own reasons."

"And those reasons are?" Sona asked, arriving on the scene with her peerage.

Itachi's gaze shifted to her, his eyes narrowing slightly. "That's for me to know. But I will tell you this—stay out of my way, and you won't get hurt. Push me, and I won't hesitate to show you just how insignificant your power is compared to mine."

Rias's aura flared dangerously, but before she could respond, Koneko groaned, pulling herself to her feet. "Rias... he's different," she said weakly. "His energy—it's not just Senjutsu. It's something else. Something… darker and dense."

She looked at Itachi and spoke, "How can you know about her truth, and how can you use Senjutsu that is stronger than mine?" Koneko spoke as she only wanted to know how this human could use Senjutsu so effectively when attacked suddenly. If he took time to respond, then it would mean he hadn't been using it since birth or wasn't born with it. But seeing him attack her so effortlessly, it was clear he was born with it.
