Chapter 780: The Plan with No Flaws

The Plan with No Flaws

“…No one would be stupid enough to test that,” he said, almost amused. Then, after a beat, his eyes flicked toward Leon.

“And if they are… we’ll make sure it’s the last mistake they make.”

Last thing Black felt like doing was smirking. That expression just wasn’t necessary.

A sharp dip of his head showed he agreed.

“It will be done.”

Right away. Not a pause. Clear on every point.

For just a breath, Leon kept his eyes locked on theirs, checking for any words hanging in silence. Slowly after that, he shifted backward, the tightness across his shoulders softening – still present, yet managed now.

Leon looked satisfied.

It clicked without force. A quiet fit where things just stayed.

Clean.

Simple.

Effective.

Might have had flaws – yet near enough to work without fixing.

And most importantly –

No visible flaw.

A quiet idea, slipping under the radar – simply because nothing about it asked questions. It stayed unnoticed, not by trickery, but by design.

A stillness settled in once it happened. Not oppressive – just there.

Even the women –

One who pushed back just seconds earlier –

Now stood silent.

Thinking.

Flickering glances. Thoughts turning corners. Pieces clicking into place once more.

Still watching Leon, Rias shifted her arms, pulling them across her chest a second time. A small tension crept into her grip, knuckles pressing fabric without sound. Not looking for failure, yet studying every shift in his posture – small breaks matter more than collapse.

Nothing turned up when she looked.

Hardly a simple task, really.

A hush of air left her mouth, faintly irritated.

“…This… might actually work.”

Her voice held a question instead of certainty.

Yet her tone wasn’t brushing it aside.

Back slightly bent, Syra dragged fingers through bright green strands, face softening into something like surprise. Her eyes held a look she didn’t want to give.

“…I hate how good this is.”

A small curl touched her lips.

“Seriously… this feels like a trap even when we know it’s ours.”

Kyra stayed calm, offering just a brief, careful nod. Not once did her focused gaze shift away from Leon.

“…There’s no opening.”

For a moment she stopped. Then, softer than before, she went on

“No wasted movement. No loose ends. Even the risks are… placed.”

Calm as a pond at dawn, Cynthia’s voice came next – though her gaze had turned more alert, cutting through like light on glass.

“…At least, none obvious.”

Fingers brushing her chin, she angled her head just a touch, eyes tracing Leon like he was a riddle written in scars. The silence between them stretched thin, filled only by the weight of what wasn’t said.

“Which is exactly what makes it dangerous.”

A breath hung still. The space between us tightened like a wire. Quiet pressed in from every wall. Then nothing moved at all

Something about it felt off, even though it was impressive.

Leon smiled faintly.

Not proud.

Not arrogant.

Just… satisfied.

“That’s enough.”

The words weren’t loud.

Yet those lines sliced straight across the space, unwavering, done.

Then –

Every face passed before his eyes once more.

Slow. Measured. Intentional.

Like a scale tipping slowly under their weight once more.

“…You’ve signed the contract.”

“…You’ve heard the plan.”

A pause.

A single tap of his fingers on his arm, slight yet intentional.

“…Now you may leave.”

A quiet voice shaped each word. Stillness filled the air between them.

Still, their presence mattered.

That sort left no room for debate.

Still –

no one moved.

Not immediately.

A quiet change moved across the space.

Eyes flickered.

Breaths slowed.

It wasn’t hesitation.

Something else it was.

Out of everyone, Rias ended up speaking first.

Forward she moved, just a bit, heels whispering across the floor. Down went her arms now, uncrossed – shield dropped, tension eased.

“…When are you leaving?”

Her voice was steady.

Yet not quite as harsh now.

Not demanding.

Not commanding.

Just… asking.

Her eyes flicked toward him before settling on Syra again.

“…Yeah,” she added, quieter now. “You don’t drop something like this and just disappear without a timeline.”

Fingers clenched, Kyra stayed silent – her eyes turned sharp.

Cynthia remained silent – watching.

Leon looked at Rias.

For the first moment ever –

A flicker of silence lived in his gaze. It stayed just beneath the surface, never naming itself.

Not calculation.

Not certainty.

Something… deeper.

A breath passed before he looked away. His eyes stayed fixed on hers just an instant past what felt normal.

His shoulders relaxed – only a little.

“…I don’t know.”

It hit differently than they thought it would.

A quiet hush hung there, odd yet unfinished, almost as if a key thought slipped away before it could be spoken.

Frowning slightly, Nova moved ahead, her expression shifting with sudden uncertainty.

“…What do you mean you don’t know?”

For a moment, Leon stayed quiet.

A quiet curve touched his mouth again – tight, barely there… the sort that kept secrets close. Not loud. Never giving anything away.

“When the time feels right.”

Fingers scraping slowly over skin, Syra exhaled low through her nose – eyes narrowing as she turned his way. A tired sound escaped, muffled by palm still pressed to forehead.

“…That’s not an answer.”

It didn’t come out harsh, yet a quiet irritation lingered – seen before, like something worn thin over time.

She whispered the words low, almost to herself.

A small laugh nearly slipped out from Nova, yet she kept it inside while focusing on Leon’s movements. Stillness stayed with her as his actions caught every bit of attention.

Frozen in place, Leon stayed silent.

Quiet settled around him instead of words. Silence took the place where reasons might have been.

There it stayed, the quiet hanging like a held breath. Not rushed. Not broken.

Then –

He shifted.

Back easing into the chair, like the outcome was set years ago. The weight of it pressed close, silent, certain.

“I’ll enter seclusion here.”

That –

It gave them reason to stop for a moment.

It wasn’t the choice that caused it. Instead, something else played a part.

Yet due to location.

Mia echoed the question, hesitation trailing behind each word. Her gaze drifted past faces, lingering on corners where shadows pooled. The sound of her voice was less sharp than theirs – more curious, somehow fragile. A pause settled after she spoke, wide enough for doubt to slip through.

A flicker of agreement passed through Leon’s eyes. He held the look without shifting.

“This room.”
