Ep 4. Guardian of the Depths

Hajime and Yue make their way to the bottom of the labyrinth where they encounter a guardian known as the Behemoth. The Behemoth proves to be a formidable opponent as it unleashes multiple attacks on the duo. Despite their best efforts, Hajime and Yue are unable to inflict any significant damage on the Behemoth as its regenerative abilities keep it alive. It is then that Hajime realizes that he needs to use the power of his transmutation magic to defeat the Behemoth. With the help of Yue's magic, Hajime is able to convert the Behemoth's body into salt, ultimately defeating it. However, the victory was not without consequences as both Hajime and Yue are gravely injured during the battle.
