A flick landed squarely on the boy’s forehead.

“Ow… that hurts!”

And it came from none other than Elsa, who’d always doted on him.

Before Roy, Airi shyly lowered her head, face flushed crimson, fingers tightly clutching her soft skirt.

“Roy! What nonsense are you spouting!”

Aisha’s cheeks burned just as fiercely.

Yet she scolded her sister Airi on her behalf.

Even though the boy was Roy—the one nestled deep in her heart.

She hated being harsh with him, let alone striking him.

She knew Airi couldn’t refuse anyone… especially not Roy.

If Roy ever had wicked thoughts, Airi would be a helpless lamb waiting to be led astray!

Worse—she’d wash herself spotless and offer herself up willingly!

Even Aisha might… no, nonsense!

Aisha refused to let Roy turn into a bad boy.

When strictness was needed, she’d steel her heart.

Clearly, Sister Elsa had misunderstood.

Rubbing his head, Roy explained pitifully, “Elsa… please hear me out.”

“I’ve been at the Adventurer’s Guild all day, listening to Hero tales until my ears ache.”

“I just recalled what they said.”

“When a Hero receives the Goddess of Light’s blessing, a sacred mark appears on their body.”

“I only wanted to confirm if Airi truly became the Hero!”

“Whether… a divine mark has surfaced on her!”

The boy’s voice brimmed with excitement.

Naturally—the Hero held extraordinary allure for boys.

It was the dream every youth chased.

Adventurers came a close second.

Roy, gentle and gifted at healing hearts (especially older sisters’), had chosen herbal apprenticeship—aiming to be an alchemist.

Aisha trusted his explanation.

“I believe you, Roy.”

Silent until now, Airi slowly let her dress strap slide down her shoulder.

The pure white band slipped away, revealing delicate, snow-pale shoulders that begged protection.

From Roy’s angle, he glimpsed the tender swell beneath her loosened dress…

Roy’s face flared red—as if he’d swallowed a raw chili!

Had Aisha not caught her sister’s movement…

Airi might have stripped completely.

If Roy asked.

She’d bare even her most private parts…

Without hesitation.

“A-Airi! Stop this foolishness!”

Elsa seized Airi’s arm, halting her.

Airi looked up, dazed and confused. “Only Sister and Roy are here… it’s fine for me.”

“It’s not fine!”

Aisha hugged her sister’s shoulders tight.

She silently blamed herself.

Too busy lately—she’d neglected Airi’s upbringing.

Airi stayed cooped in her room, never stepping out.

Before Roy arrived, she’d barely spoken to anyone, let alone made friends.

No wonder she lacked basic life sense…

Or knowledge of intimacy.

She was a blank, pure page.

Without guidance, ill-wishers could stain her easily.

“I can’t explain everything now.”

“But listen—except for your future husband, no girl should bare her body to anyone!”

“…”

Hearing this, Airi glanced at Roy instinctively.

Then she ducked her head, fingers twisting nervously.

H-husband…

The only one she’d ever choose was Roy.

Without him, she’d stay unwed forever.

But she couldn’t tell her sister that.

Besides… didn’t Elsa harbor special feelings for Roy too?

After a pause, Airi whispered, “I understand, Sister.”

Aisha pulled Airi aside, separating her briefly from Roy.

Aisha tried to examine Airi’s body.

But Airi, clinging to her lesson, murmured timidly, “This… is only for my h-husband to see.”

When had she ever been this stubborn?!

Aisha was utterly flustered.

She added hastily, “As your same-sex sister, I’m allowed too!”

“Haven’t I bathed and cared for you all these years?!”

“Honestly—you get a man and forget your sister…”

Aisha sighed at her lovestruck sibling.

Airi lowered her head, blushing. “Then… please check on behalf of my future husband.”

“…”

This fiercely loyal wifely aura—where did it come from?!

Even Aisha envied Airi’s future husband.

Roy waited alone nearby.

A sharp gaze from Elsa suddenly pinned him.

Roy: ?

He shook his head, dismissing it.

He’d wait calmly for the results.

One thing was certain—whatever they found was good news.

It proved history’s turning points weren’t fixed.

Reborn, he could still avert the worst future!

Relief lightened his heavy heart.

Soon, Elsa and Airi returned.

But to Roy’s surprise, their expressions were strange.

They exchanged uneasy glances, too shy to speak.

“Elsa, Airi—what’s wrong?” Roy asked, concerned.

Aisha pressed her lips together, chest heaving before him.

She struggled for words to explain their discovery.

Airi—the girl with soft, pale blue eyes—tugged Sister Elsa’s robe hem.

“Just… let Roy see it directly.”

“I suppose we must.”

Roy was baffled. Why were they speaking in riddles?

Before him, Aisha and Airi slowly lifted their robe and dress hems at their lower abdomens.

Their shy, lip-biting expressions were bewitching; golden hair trembled with their bodies.

What a breathtakingly revealing sight.

Even Roy—a Succubus—blushed fiercely.

Then he understood their shock.

He gasped.

As their slender waists were exposed, sacred marks glowed on their fair skin:

“Wings of Protection” and “Radiant Spear.”

But Roy’s past-life memories insisted—

The Goddess of Light’s mark should be one symbol:

“A holy spear guarded by twin white wings.”

Why was it split now?

Had the Goddess’s blessing…

been granted to both Elsa and Airi?!

A dual-bodied Hero?!
