The top four fighters in the preliminary have been decided. With her semifinal match against Daewi drawing near, Mira is suddenly approached by Oh Seongjin, a martial artist and successful businessman, with a marriage proposal. She agrees to marry him in exchange for his promise to restore her family’s dojo and spread the Moon Light Sword Style around the world, but marrying him means she must withdraw from the tournament… and Mori and Daewi are not okay with this.

Daewi shows no mercy in his fight against Mira with the goal of getting the money to help his friend, Woo Seungtae, who suffers from an incurable disease. Mori handily defeats his own semifinal opponent, Brazilian jiu-jitsu user Byeon Jaehee, but is angered by Daewi’s method of defeating Mira by targeting her injuries. Daewi, meanwhile, learns that Seungtae has taken a turn for the worse and strengthens his resolution even further. Then, amidst all this, Mori and Daewi face each other in the final round.
