Modern: My Broken Sign In system

Being isekai'd into another world was the dream of every anime and light novel fan.

Ben was no exception.

He had spent countless nights imagining himself awakening in a fantasy world filled with magic, monsters, beautiful companions, and limitless adventures. So when death finally came, he believed his wish had been granted.

Except...

“What the hell is this?!”

Ben stared at the familiar skyline before him in disbelief.

“This is just Earth!”

Well... almost.

The only obvious difference was its name.

Earth was now called Solar-3.

The countries, history, technology, and society all appeared identical to the world he had left behind.

Just as disappointment set in, a mechanical voice echoed in his mind.

[Sign-In System Activated.]

Ben's eyes lit up.

“At least I can become a billionaire with this.”

His excitement lasted exactly one second.

[Congratulations! You have signed in and obtained: Fireball Spell.]

“...”

“...What?”

“There isn't even mana in this world! How the hell am I supposed to cast magic?!”
