I'm Standing on 1,000,000 Lives S01E07 - The Warrior of Light and the Stranger of Darkness

Yotsuya's party is trapped by the Deokk soldier Kamilto in a cave filled with ancient traps. Yotsuya becomes separated from the group, leaving the other three party members and Kahvel to fight a formidable gargoyle. Things look desperate when the gargoyle takes down Kahvel, but then Shindou reaches rank 10 and job-changes to a Warrior (Sword), allowing her to put up a fight against the gargoyle.
