The Magic Club Can Save the World Too

He woke up to find the bed collapsed, the house gone, and the school vanished without a trace.

The tragic genius of magic, Bai Chi, discovered that he had traveled 500 years into the future, with nothing but a wand by his side.

Worse still, this era hated magic, technology had regressed, and people worshiped monsters called "gods." Anyone who saw a magician would burn them alive.

Bai Chi: Here's the problem. I just cast a Levitation Charm in front of everyone. How do I explain that it was only an illusion?

-

In the Age of Collapse, Earth was invaded by creatures from another world, and humanity was reduced to slavery.

[You are a great mage summoned to this world. You must repel the invaders and rebuild human civilization.]

[Gather your club members and march toward the dawn! Earth's future is in your hands.]

"...That's quite a rousing slogan," Bai Chi said after a moment's thought. "But didn't you forget to give me my golden finger?"

He had maxed-out damage, but was a fragile mage who was useless in close combat. His teammates included, but were not limited to:

A cauldron killer who had never passed Potions;

A shut-in research fanatic who hadn't bathed in half a month;

A freak with zero magic who had somehow gotten into a magic academy;

A chuunibyou girl whose one redeeming quality was her enormous appetite...

-How the hell are we supposed to save the world?!!

* No CP, group transmigration, and a style that's probably chuunibyou, silly, and passionate.

* An alternate setting in the future, with a few steampunk and Lovecraftian elements. My own take on magic, with lots of original worldbuilding, so don't take it too seriously.

* Let's keep things civil. No need to notify me if you drop the story.
