Arihito and his party have accidentally ended up on the third floor of the first labyrinth far ahead of their time. Even with the powerful back up of having "Death Sword" Elitia on his team, the risk of so many low level Seekers travelling together may be too much!

Arihito, who had a chance encounter with the secret god Ariadne, was ranked first in the eighth district. The group is about to take the promotion exam to challenge the seventh district, but monsters overflowing from the labyrinth attack the city...!

Just as Arihito and his party are in the midst of quelling a stampede, a giant monster capable of overpowering his support and defense skills appears. With civilians to protect and a formidable foe to defeat, Arihito fears his luck has finally run out. Yet when all hope seems lost, one Hidden God's powers will manifest and flip the battle on its head...
