Echidna leaves during the night, and the next morning Ymir finds the real Cattleya and challenges her to a fight. On Lana's insistence, Leina tries to help and finds the Giant Slayer weapon which she gives to Cattleya, who uses it to defeat Ymir and decides to enter the Queen's Blade. Cattleya later gives Leina a new sword. While leaving town, Leina runs into Risty on the road.
