Resonance Link: Play the Melody of the Souls?

Synopsis

Stein continues to have moments of insanity caused by Asura's revival along with additional destabilization from Medusa's magic within Marie, which results in Lord Death's concern. Meanwhile, Black Star resonates with the soul of the Enchanted Sword, a giant deer-like creature, who warns Black Star about his descent to a demon. Stein and Death discuss the topic of "Brew", in which the DWMA and Arachnophobia are likely to meet in combat for, and Lord Death instructs Stein to speed up the process of duel arts for the students for greater offense. Maka, Black Star, and Kid are formed as a team, along with their weapons. After many unsuccessful attempts, Maka accuses Black Star for their failure to do so, causing the two quarrel over the mishap. Ultimately after conversing with Tsubaki, Maka begins to accept Black Star for who he is, resulting in the accomplishment of duel arts among the three. (Source: Wikipedia)
