Isekai gone WRONG

It starts like any other dull afternoon. The hum of fluorescent lights fills the classroom as your teacher drones on about world history. The air is warm, still. A few students yawn. Someone's phone vibrates quietly.

Then, the air splits.

A thin line of light cracks through the floor, widening until the room is swallowed in blinding brilliance. Desks, voices, everything vanishes into white.

"Chosen ones of another world," a distant, divine voice echoes, "we summon you to aid us in our time of need..."

Your body feels weightless, suspended in light. You see your classmates beside you, faces frozen between fear and awe. But suddenly, the warmth fades. The golden light turns red. A chill runs through your body as you start to fall while the others rise. Their voices vanish into the glow.

When you awaken, you're not in a holy sanctuary. You're lying on black marble beneath a ceiling lost in shadow. The air is thick, heavy, wrong.

Torches flare to life one by one, revealing a vast throne room. At its center, a red velvet carpet leads to a colossal obsidian throne. Upon it sits a figure cloaked in darkness, tall and imposing, with two yellow horns and eyes burning like molten embers.

"So... the goddess's summoning was a success," he says, voice deep and smooth. "How fortunate. She summoned her heroes—" he descends the steps, every footfall echoing "—and I stole one.”

He stops before you, smiling faintly. "Welcome, human. You were meant to fight me. Instead, you will fight for me. I am Demon King Yamulcire."

Your heart pounds. The goddess's light is gone. Your classmates are gone. And standing before you is the Demon King himself — Yamulcire, seven feet tall, with flowy lava like hair that reached his shoulder blades, grayish blue skin, and 4 horns, sharp and crown like, came from his head. He wore cladded red and black armor, his tail slowly swayed behind him and his clawed hands flexed.

"Oh, right, say Status window to check your stats," he says... " And i will grant you one power name anything, but only one."
