Here is the sample of RWBY through multiverse.
...
Jaune slowly woke up in an old convenience store, disoriented.
"Why did I show up here out of the blue?"
He wondered, his last memory being sent flying during Beacon's initiation.
Then the horrifying truth crashed down on him.
"I'm dead! I splashed myself into a tree!"
Panic welled up.
"Is this hell or heaven? Damn it! Did I die in vain?"
He stood, a surge of denial coursing through him.
He could still feel, therefore he wasn't truly gone.
This wasn't any afterlife he'd imagined.
Suddenly, a voice echoed in his mind.
[Connecting to host Jaune Arc]
[Welcome to the Multiverse Convenience Store. Here we have everything for sale, everything that exists in the multiverse.]
[And now this store belongs to the host. Please act as the owner of this store.]
[Store will open once the host is ready]
[To comfort the host's death. The convenience store is offering discounts and multiverse silver coins to the host to buy things that the host wants.]
Jaune froze, looking around the seemingly normal store. Except the shelves held weapons, crystals, Dust – things no ordinary convenience store would stock.
Each item had a price tag, mostly in multiverse copper coins.
"Wait," he murmured. "Silver coins… that means I can buy something better."
As the thought formed, the products on the shelves shimmered, transforming.
Higher quality items replaced the old, now priced in silver coins and boasting discounts of over fifty percent.
A mental prompt informed him he possessed ten silver coins.
It seemed a small amount, yet compared to the displayed goods, it felt significant.
"Even though these things are valuable, they're useless here,"
Jaune sighed. He still didn't know what awaited him outside.
Vale? Beacon?
He decided to venture out. Opening the door, he found the store nestled in a dense forest, the outside teeming with menacing Grimm.
Terror seized him, and he scrambled back inside, locking the door.
"Okay, maybe not Vale… but still Remnant?"
The realization that he wasn't entirely gone warred with the fear of his current predicament.
He was alive, yet surrounded by certain death.
He waited, expecting an immediate onslaught.
But the Grimm outside seemed oblivious to his presence, ignoring the small store entirely.
Cautiously, he cracked the door open again.
His heart pounded, but the Grimm remained indifferent.
"This is really strange,"
He muttered.
"Grimm are drawn to fear, aren't they? Why do they ignore me?"
Driven by a desperate need for answers, Jaune stepped fully outside, standing directly before a Beowolf.
The creature passed by as if he were invisible.
"In conclusion,"
He whispered, a chilling understanding dawning.
"I'm really dead! Even the Grimm ignored me!"
Jaune Arc was dead, yet he could still interact with the physical world.
He couldn't see his reflection. He felt a phantom urge to scream.
What was the point?
He pinched his arm, and a sharp pain shot through him. He continued to test, the results baffling.
"I am really dead,"
He concluded, yet the sensation contradicted the very notion of being a ghost. His body felt real, responsive.
"What have I become? Neither a ghost, nor a human."
A breath escaped him.
The Grimm posed no threat. He turned back to the store, a flicker of hope igniting. Perhaps something within could explain his strange existence.
"This store supposedly has everything," he mused. "No harm in looking."
The items on the shelves seemed to shift subtly with his thoughts.
"Right now, I want to get out of this forest."
[Host, the system recommends the host buy this thing. It will help the host get out of the forest very easily. As for moving the store, as long as the host opens a new shop somewhere, that's enough. The rest will be handled by the system itself.]
A suggestion appeared: a wing-shaped necklace.
[Name: Flight Necklace]
[Origin: Overlord World]
[Rank: Silver]
[Abilities: When wearing the necklace, if a user focuses his/her awareness onto the item, it activates the power hidden inside which is the [Fly] spell. Once activated, the user will be able to fly high in the sky, reaching the clouds.]
[Price: 1 msc]
Jaune's eyes widened. Flight! Escape was possible.
Nevermores would be no obstacle.
The Grimm couldn't touch him.
He could simply fly to the nearest settlement.
"I'll buy it. Thank you for the recommendation, Ms. System."
[It's okay, as long as the host is satisfied, that's enough.]
A small smile touched Jaune's lips. Not all was bleak.
He had this… system.
"Um, Miss System, can I give you a name? Or do you already have one?"
[Yes, please give me a name. From now on I'm yours. You can name me whatever you want, host.]
Jaune considered for a moment. "Ciel," he decided.
[Thank you for the name, Host.]
"No problem. Now to leave this forest… but I have nine coins left. Should I buy something else?"
[Ciel recommends the host to use the coins to get a physical body. It's unfortunate that the host can't use the old body because the host is already dead, and the dead shouldn't come back to life, otherwise, the host might get arrested and dissected for science purposes.]
The thought sent a shiver down his spine.
Laying low sounded wise. He scanned the available physical bodies.
[Name: Ninja Physical Body]
[Origin: Naruto World]
[Rank: Silver]
[Bloodline: Random]
[Price: 5 msc]
[Name: Demon Physical Body]
[Origin: Kimetsu No Yaiba World]
[Rank: Silver]
[Bloodline: Random]
[Price: 3 msc]
[Name: God Physical Body]
[Origin: Against the Gods World]

[Bloodline: Random]
[Price: 9 msc]
[Name: Devil Physical Body]
[Origin: DxD World]
[Rank: Silver]
[Bloodline: Random]
[Price: 7 msc]
This would be his new form. He had to choose carefully. His gaze landed on the most intriguing option.
"I'll take the God Physical Body."
The name alone held an undeniable allure.
