A magical “time” that you have never experienced before begins


character image Auru

A mysterious island floating in the indigo sea
The towering gold mine in the middle of the island has been the site of legends about “Golden Light Stone and otherworldly monsters” since ancient times.

“Seldomly, monsters manifest themselves in this world from another world that intersects with the tunnels of the gold mine.
When the ‘Golden Light Stone’ with mystical power and its spirit ‘Auru’ become one, they will be sealed.”

You are now witnessing the first period of intersection in hundreds of years.
Please gather the four fragments of the Golden Light Stone scattered in the tunnels to empower Auru, and protect the gold mine together.
