The Heroine is My Stepsister, and I'm her Final Boss
Chapter 468 - 465: Crown and Consequence
The fracture happened without ceremony.
Sekhmet moved first.
There was no warning, no declaration, no dramatic speech to mark the moment alliances snapped. One second the chamber was thick with tension; the next, it was war.
Atlas closed the distance in a single step.
He did not test her. He did not circle.
He punched her.
His fist drove straight into her abdomen with enough force to collapse stone towers. The impact thundered through the chamber, splitting the floor beneath her boots and sending a shockwave rippling through the air.
Sekhmet’s body bent around the strike.
For half a second.
Then she grinned.
She flew backward regardless, blasted through three frost pillars before slamming into the far wall of the citadel. Ice exploded outward in shards and dust.
She stood up immediately.
Spitting blood.
Laughing.
"I was waiting for this!" she shouted, wiping her mouth with the back of her hand. "Finally—someone worth hitting back!"
She launched forward like a solar flare.
Atlas met her mid-charge.
Their collision detonated the air between them.
The castle shook violently as golden-black force met raw sunfire. Frost-lined walls cracked, ceiling spires fractured, and the storm outside roared louder in response.
Sekhmet’s fist slammed into Atlas’s jaw.
The impact would have decapitated a god.
Atlas’s head snapped sideways—but he didn’t fall.
He answered with a hook that tore the floor open beneath her feet.
They separated only long enough to strike again.
The second collision was worse.
Every time their bodies connected, the entire citadel trembled as if caught between tectonic plates.
Meanwhile, the rest of the chamber erupted.
Pegasus surged toward Sekhmet’s team, lightning flaring in disciplined arcs rather than wild bursts. He tackled one of her true-blooded demigods shoulder-first, driving him into the ice wall before unloading rapid, concentrated strikes.
Iris engaged two opponents simultaneously, spear flashing in tight patterns, parrying one blade while slicing at the other’s exposed flank. She fought clean, efficient, controlled—but there was strain in her eyes now.
Kael locked shields with a broad-shouldered demigod wielding twin frost axes. The clash rang like iron gates slamming shut.
Nephra’s chains lashed through the chaos, catching a charging enemy mid-step and dragging them down into shadowed frost.
Aron remained mobile, firing bursts of focused solar arrows that disrupted formations and forced Sekhmet’s squad to split.
At the far end of the chamber, the Ice Monarch watched.
And laughed.
The sound was low and deliberate.
"So eager," he murmured. "So predictable."
But he did not intervene.
Not yet.
Sekhmet and Atlas collided again.
This time she caught his wrist mid-swing and twisted, redirecting the momentum. She slammed her knee upward into his ribs, flames erupting along her leg.
Atlas absorbed it.
He countered with a downward elbow that split the ice beneath her and forced her into a knee.
She grinned up at him from the crater.
"Harder," she said.
Atlas obliged.
He drove his fist into her again, and she rocketed across the chamber, crashing through the remnants of the throne dais.
Before she could rise, Atlas was already there.
She caught his next punch with both hands.
The impact shattered her forearm armor and cracked the floor beneath them again.
Their faces were inches apart.
"Is this it?" she asked, eyes blazing. "Or are you still holding back?"
Atlas’s answer was silent.
He headbutted her.
The shockwave threw both of them apart.
While the demigods clashed around them and the citadel fractured further, something else moved.
The dragon.
Still in humanoid form, chains of frost-law binding her wrists and throat.
She turned to the Ice Monarch.
"You’re enjoying this," she said.
The Monarch’s gaze did not shift from the chaos.
"They would have turned on one another eventually."
She stepped closer despite the restraints.
"Release me."
"No."
"Why?" she demanded. "Why not let me leave? What do you gain by keeping me?"
"You are anchor," he replied calmly. "You stabilize this layer. Without you, the balance shifts."
"I don’t care about balance," she snapped. "I care about freedom. My Freedom."
He looked at her then.
"Freedom is indulgence girl, why don’t you understand?"
"Then kill me," she said.
"I will not!"
She stared at him.
"And why is that?"
He said nothing.
Her voice dropped.
"Because I am your daughter."
He did not deny it.
She shoved him.
Hard.
It was not a strike of power—it was frustration made physical. He staggered half a step.
She reached up.
And ripped the crown from his head.
The Ice Monarch’s eyes widened for the first time.
The citadel trembled violently as the crown left him.
Within the jagged crystal structure, suspended in a hollow core, glowed a drop of liquid gold.
Amrit.
She didn’t hesitate.
She threw it.
Straight toward Atlas.
"It’s in there!" she shouted.
Sekhmet saw it.
She moved faster than thought. 𝕗𝚛𝚎𝚎𝐰𝗲𝗯𝗻𝚘𝚟𝚎𝗹.𝕔𝐨𝕞
She intercepted the arc, catching the crown mid-flight before it reached Atlas.
Her boots carved trenches into the ice as she landed.
"Mine," she said through bloodied teeth.
Atlas was on her instantly.
He drove a brutal gut punch into her midsection.
The sound of the impact echoed through the chamber like a cannon blast.
Sekhmet coughed blood and air at the same time.
The crown flew from her hands.
Pegasus reacted without thinking.
He lunged.
Caught it.
For half a second.
Then one of Sekhmet’s squad members smashed into him from the side with a two-handed strike. Pegasus was flung across the chamber, crown ripped from his grip mid-flight.
It spun through the air.
Aron leapt.
Missed.
Kael reached—
Too late.
The crown struck the ice and slid.
Iris dove.
Her hand closed around it.
She rolled and came up in one motion, clutching the jagged crystal.
Atlas saw her.
"Iris!" he shouted. "Run!"
There was no hesitation in her eyes now.
Only clarity.
She nodded once.
And ran.
She bolted toward the shattered exit of the citadel, sprinting through collapsing frost corridors as storm wind tore inward through the broken ceiling.
The Ice Monarch’s face twisted in fury.
"Legion!" he roared. "After her!"
New waves of ice demons began forming at the edges of the chamber, summoned from the storm itself.
Sekhmet wiped blood from her mouth and grinned again, despite the damage.
She turned toward the exit.
"This isn’t over!" she shouted at Atlas before launching after Iris.
Her squad followed instantly.
Pegasus scrambled to his feet and sprinted after them.
Kael and Nephra disengaged and moved to support.
Aron fired two covering shots into a wave of forming demons before retreating through the exit as well.
Within seconds, the battlefield emptied.
Only Atlas remained.
The Ice Monarch stood opposite him.
Crownless.
Calm again.
"You let them run," the Monarch observed.
Atlas flexed his hand once.
"I don’t need them here."
The Monarch’s lips curled faintly.
"You think the Amrit is in that crown."
Atlas stepped forward slowly.
"I know it isn’t."
The Monarch tilted his head slightly.
"Oh?"
Atlas’s eyes burned brighter.
"You’re too careful to keep something like that exposed in battle."
The storm outside intensified again.
Ice began reforming around the throne.
The Monarch spread his hands slightly.
"And yet you fought for it."
Atlas’s voice was steady.
"I fought for...control."
The Monarch studied him carefully.
"And now?"
Atlas stopped five paces away.
"Now," he said, "you tell me where the real Amrit is."
The Ice Monarch smiled.
It was not friendly.
"You believe I would store eternity in a bauble?"
Atlas did not blink.
"No."
The Monarch walked down from the broken dais, frost trailing behind his boots.
"You are different from the others," he said. "You see patterns. Indeed the one and only Guide."
Atlas’s gaze never left his.
"So answer."
The Monarch’s eyes gleamed pale blue.
"firat answer me Why?"
Atlas’s voice lowered.
"Because I need it demon, simple as that."
The Monarch circled him slowly.
"And what would the Guide of Hell do with life unending?"
Atlas didn’t answer immediately.
The storm’s roar filled the silence.
Finally, he spoke.
"Survive."
The Monarch’s expression sharpened.
"survive? You... fear something?"
Atlas’s jaw tightened.
"Yes."
The Monarch stopped circling.
"And you believe Amrit will save you."
"I believe," Atlas replied, "that if I don’t take it now, I won’t get another chance."
The Ice Monarch’s smile returned.
"Good," he said.
Then the temperature dropped.
And the throne behind him began to split open.
Something deeper stirred beneath the ice.
"Then take my daughter with you as well, only then the amrit can be yours." He beckoned.
