As Saya finds she is no longer able to connect with Black Gold Saw, Yuu sends her own mind to that of Strength's to try and talk to Mato, who finally regains consciousness and attempts to hold back Black Rock Shooter. However, Mato starts to hesitate when she realises how she had been running away from her own feelings. Just then, Strength starts to speak and goes beserk on Black Rock Shooter, revealing she is actually the real Yuu. Strength, the Yuu that Mato knew, explains how she gained emotions when Yuu, who was filled with an extraordinary amount of sorrow, was able to contact her, stopping her from dying at the hands of Black Rock Shooter. Finding a world of fighting better than the world she lived in, Yuu decided to switch places with Strength so that she would have to face reality instead. Meanwhile, as word reaches school that Mato had not returned home, Yomi feels a pain in her heart and remembers her friendship with her, which in turn causes Dead Master to reawaken.

As Strength prepares to sacrifice herself in order to stop Yuu, Mato becomes determined to stop Black Rock Shooter from killing her. She ends up inside a blue world, where she herself is Black Rock Shooter, standing against Insane Black Rock Shooter. As Kagari and Arata also recover their painful memories, the revived people of the other world combine their strengths to give Mato the power to defeat Insane Black Rock Shooter, uniting the world as one. Upon regaining herself, Mato finds Strength in a weakened state, who assures Yuu that she'll be able to make friends in the real world and gives her thanks to Mato before disappearing into the wind. Afterwards, Yuu returns to her original body whilst Mato, having regained consciousness, reunites with Yomi. As life returns to normal, Mato, Yomi, Kagari and Yuu all become friends together whilst Strength returns to her place in the other world, alongside Black Rock Shooter. The episode ends with Black Rock Shooter saying she will continue fighting.
