Eruka frees Free and he quickly takes down a hoard of guards before escaping, revealing that he is immortal. Meanwhile, Maka and Soul attempt to grow stronger through Stein's training method, starting by insulting each other, which causes great tension between the two. Maka, Soul, Black Star, and Tsubaki travel to London only to run into and face Free, who further reveals himself to be capable of ice-based magic and is a werewolf. Black Star exhausts himself early on using the new Fey-Blade mode of Tsubaki, while Maka cannot initially use Soul due to their disagreeing wavelengths. She eventually fights past the pain of wielding Soul and, with Tsubaki's advice, the two reform their bond and are able to merge their soul wavelengths.
