Objective: Take Mr. J to the Theatre and continue the present version of the documentary
Rosemerix Theatre · Present Edition Begins
The party moved into the theatre.
Mr. J stood near the screen.
"The story isn't over," he said.
"I continued my research."
Next replied:
"We don't know what's left.
Let's sit and see."
Everyone took their seats.
System Update:
Movie Begins – Rosemerix Mansion: Present Edition Animation
The screen flickered.
A title appeared:
Created by: Witch of Wizakon Magic Tower – Rosy Fermina
"I continue the present story.
I will tell you the truth between past, present, and this world."
The title faded.
The story resumed.
The Forgotten Timeline
After Mr. J's five-year research, the truth emerged—
a hidden chapter between the mansion's fall and its rebirth as a lodge.
Before Mr. J repurchased the place,
the owner was Azberito Merixia,
who had bought it from Ooko Joko, a merchant also known as Professor Jaspheleos.
"Do not confuse Professor Jaspheolus with Professor Jasfer," the narrator warned.
"They are the same—an alchemist, single, and secretive."
The Forbidden Origin
Rosy was not human.
She was a homunculus, created by Professor Jasfer—his beloved daughter,
but born of forbidden alchemy.
She fell in love with Merix, the young merchant.
Together, they planned to destroy the palace and escape.
To protect his research,
Professor Jasfer made a contract with the demon Luci,
offering his soul.
Luci defeated Rosy and imprisoned her in the last room of the mansion.
Demon King Revealed
After sealing Rosy,
Luci declared:
"I will conquer this world with horror."
He became Demon King Luci,
ruling from Dream Canor, a cursed region in the southeast.
The Calm Before the Curse
Merixia purchased the lodge.
For ten years—until 470 Blix Calendar—
no monsters appeared near the lodge or town.
The seal held.
The horror slept.
Interval Begins…
Rosy's Awakening · The Curse Unleashed
The story resumed.
Mr. J re-entered the mansion, determined to uncover the truth behind Rosy's mysterious death.
He developed a theory—one that led him to the sealed room on a stormy night in the year 473 of the Blix Calendar.
He broke the seal.
Inside, he saw her—Homunculus Rosy.
She laughed.
"Finally… my revenge begins."
She shattered her shackles, struck Mr. J with immense force, and vanished into the night.
He lay unconscious outside the lodge.
Three days later, Mr. J awoke.
But the horror had already begun.
🩸 The First Night of Death
One year passed.
Then, in the dead of night, Rosy returned.
She battled and killed Georgoire, the sword master elf, in a fierce duel.
That same night, many others perished.
Merix, the lodge owner, confronted her.
He saw her—Rosy, dancing in blood, killing guests.
"My love… Rosy… where have you been?
Why are you killing my customers?"
Rosy turned, eyes burning.
"You are waste.
For 13 years, I was tormented alone in the last floor.
I am not human.
But you could have saved me."
"I waited… waited… waited.
Where did your love go?"
"I heard your laughter.
Your joy.
Your wife—Alima Mexia.
You think I didn't know?
You cheated."
"Let me kill you."
In a flash, his head was gone.
Rosy laughed intensely.
"I will kill Demon Lord Luci.
I will protect this world from his power.
Oh no… I'm also evil."
"It doesn't matter.
He wasted my years of life.
I was good once."
The scene faded.
A final message appeared:
"Rosy will find you in the last floor.
Defeat her to claim the mansion.
Easy Mode Activated.
Rewards Await."
Everyone in the theatre sat in shock.
