Overpowered Mage in the Fantasy World

Rain found himself in a cavern when he woke up.

He thought he must have been kidnapped, but what he saw next changed his worldview.

Skeletons walking and carrying rusty swords, a scene only seen in anime, games, and novels!

“Did I get isekai’d? Is this a fantasy world?” Rain was excited.

As an otaku himself, he loved magic and always dreamed of using it one day. His dream turned into reality when he felt mana.

He first tried to cast Fireball. His magic control was sloppy, his mana reserve was low, and it was hard to cast magic.

But with practice, he improved.

He killed skeletons, absorbed the black mana that left their bodies once they were destroyed.

He absorbed the dark mana and found his mana increasing.

“I want to learn more magic!” Determined to become a great magician like the protagonists of every anime and novel, Rain left the dungeon on a journey to explore the world.
