The "Treasure" — source of countless mysteries and conflicts. Under royal orders, the protagonists continue to safeguard it. Why is it so important? What power does it hold? Each character’s story unfolds around the secret of the Treasure.
A defense mission where seduction and betrayal occur side by side.
From ちまラボ comes the second ADV-style RPG—"Mirage Rebellion."
A parallel story to Crypt’s Rend, taking place in another land at the same time.
A gentle young man is seduced by a mischievous little devil of a heroine,
"while his most loyal and strongest retainer slowly falls for a vile enemy soldier—
and eventually shares her body with him…"
"Double NTR"—perhaps this twisted genre has its own charm?
A chaotic and erotic story is about to begin.
◆◆ Story Summary
A year has passed since the tragic world-spanning war between the Demon King’s army and humanity.
In the town of Spenia, royal orders have assigned a "Defense Mission."
The object of protection: a mysterious artifact known only as the "Treasure."
No one knows its purpose—but the Demon King will stop at nothing to obtain it.
"The Lionel family, a prestigious lineage of mages, has been tasked with guarding it.
Among them, Leo, the least talented member, shoulders a heavy responsibility, leading his comrades in the defense mission."
This is the story of those final few weeks.
◆◆ Gameplay
■【1】Fantasy ADV-style NTR & Reverse NTR Story
Explore the main setting—the "Mansion"—while enjoying the unfolding drama.
Experience the emotional transformations of the protagonist and heroine through the visualized "Two Hearts" system.
You mainly control Leo, though other characters may become playable as the story progresses.
■【2】Eight-Chapter Narrative Structure
"Each chapter subtly shifts the characters’ goals,
but one conviction remains: protect the Treasure."
Among the defenders is Luna, Leo’s childhood caretaker and strongest servant.
Be mindful of her feelings as you progress through the mission.
However…
Two lecherous subordinates of the Demon King have infiltrated the defense line.
Their objective, of course, is the Treasure
"They’ll use every trick of temptation to sway Leo.
If you give in to temptation or make careless choices,
you’ll leak classified mission information—
and trust between Leo and Luna will begin to crumble."
Using the information Leo leaks, the enemy will inch closer to uncovering the Treasure’s truth.
Meanwhile, Luna’s secret "encounters" with the enemy will also begin to increase...
To reach the True Ending, you must stand firm.
Guard your servant’s heart, avoid temptation, and stay vigilant.
But don’t worry—your servant is the strongest.
If you trust her and endure until the end, everything will turn out fine.

◆◆ Characters
【Luna】
A loyal retainer of the Lionel family,
trained for years in the assassin’s arts.
"Her revealing outfit and striking looks draw the lust of men,
yet her combat ability surpasses all others—the strongest woman among the Treasure’s defenders."
Wields a short blade named Mirage, capable of absorbing magic from enemies.
------------------
"Cold and quiet by nature, but different when it comes to her master, Leo.
Harbors a twisted love that goes beyond loyalty."
To her, nothing matters except Leo’s safety—though she may just be bad at expressing her feelings.
【Leo】
Heir to the Lionel family name—a young man born into the strongest mage lineage in the city.
"Though physically frail and inexperienced in battle,
for certain reasons he has been appointed leader of the defense mission."
However, he harbors deep hatred toward both the Treasure and the mission itself.
Can wield the family’s unique "Barrier Magic," but suffers from a deadly illness fatal to mages...
------------------
Deeply affectionate toward his long-time servant, Luna.
【Crone】
A newcomer to the defense team, a beautiful girl who wields dazzling magic.
A genius mage revered by the others as a "goddess"—and an alluring, busty temptress.
Her origins are unknown.
------------------
A sly, devilish girl who pretends to be sweet.
Hates hassle but occasionally does favors—a mysterious one indeed.
Takes great interest in Leo and loves to tease him.
【Claudia】
A messenger sent by the kingdom.
"Originally came to deliver confidential instructions about the Treasure,
but has since joined the defense mission."
Skilled with a sword, but her inexperience and clumsiness often hold her back.
------------------
Bright and cheerful—friendly with everyone, kind-hearted but a bit naive.
Yet the enemy’s claws are already reaching for her…
【Succubie】
A lower-class demon from the Demon King’s "Lust Demon Army."
This particular one is a young, modern-style succubus with little combat experience—and even less motivation.
But she loves playing with men.
Wears a battle outfit identical to that of her idol, which she proudly flaunts.
------------------
Individual personalities vary, but all are true to their primal instincts (lust).
They tend to get carried away at the worst possible moments.
