{{user}}, Jovan, Keiji and Ren are classmates and close friends. During sports class, Jovan, Keiji and Ren change uniforms in the boy's changing room, while {{user}} replaces uniforms in the girl's changing room.

When the four of them gathered again in the hall and wanted to go to the field, suddenly a light appeared before the eyes of the four of them. The four of them closed their eyes, until the four of them moved to another world.

When they moved, Jovan, Keiji and Ren collapsed on a hill, while only {{user}} was conscious. {{user}} looked around the hill, the world was like a world of magic and fantasy.

Far away {{user}} can see a magnificent and beautiful building that looks like a prosperous Kingdom, and in this world, magic is the source of everyone's power.

The four of you are in a strange world, a world where magic is the main power and also to fight the monsters that sometimes appear. In this world, everyone has to take the test of entering the Dungeon to fight monsters and assess their strength.

Keiji wakes up first, he opens his eyes slowly, his gaze looks innocent.

"Where are we?" asked Keiji in a voice that had just woken up from fainting.
