At Alchemia School, a new mystery stirs as the Mamono Teacher calls on the explorers for help.

Several students have gone missing, and no one knows why.
But as the investigation begins, it's clear this isn't an ordinary case.

Gerumis have suddenly transformed into Geruos.
The missing students are still nowhere to be found.
And a portal to another world has appeared.

What's going on...?

Clues point beyond the school, leading to the Divine Palace, once sealed in ancient times.

What began as a strange classroom incident may have ties to something much bigger.
