At Nova High School, everything looked normal — ringing bells, rushing students, and mountains of homework.
But on Monday morning, something unusual happened.

A new transfer student walked into Class 2-B.

He wore a silver badge shaped like a star, and his eyes looked like they could scan every detail of the room in one second.

“My name is Rian,” he said softly. “Nice to meet you.”

He sat by the window, never speaking again.

That afternoon, the sky suddenly turned dark — not like rain — like the sun itself disappeared. The teachers panicked, phones stopped working, and the power died.

Only one device in the entire school still worked:
Rian’s badge.

A bright blue screen appeared above it, projecting a map of Earth.

“You’re… not a normal transfer student, are you?” a girl named Mira whispered.

Rian hesitated… then nodded.

“I came from the year 2197. A solar collapse is about to begin today — in your time — and I was sent to stop it.”

Mira stared. “Why our school?”

“Because,” Rian said, “the one who will grow up to become the scientist that saves the world… is sitting in this classroom right now.”

The students gasped — but no one knew who he meant.

The dark clouds above the world pulsed like a heartbeat. Time was running out.

Rian turned to Mira.

“And it’s my job to make sure that future… comes true.”
