Labyrinth of Enslavement and Liberation [hachon]
Robin, an enhancement mage, was being treated unfairly within her party, “The Golden Wolf of the Great Masters”.
One day, Robin, who had the courage to leave the party and become a free man, heads for the labyrinth city to challenge his long-held dream, the imperfect labyrinth “Labyrinth”.
Robin went to the guild to form a new party, but was unable to form a party because reinforced mages are not a popular profession. At that time, Robin helps a girl who is in trouble at the entrance of the guild.
The girl was Llanoa, a student at the magic school where Robin once went for an internship.
Robin and Llanoa are happy to see each other again.
The two form a party and challenge the "Labyrinth.
