Kill the Disaster (難局を斬る, Nankyoku o Kiru) is chapter 50 of the Akame ga Kill! manga.
The first scene is shown when Mine and Akame are training hard, with Mine motivated because the empire's strongest is after her boyfriend. The next scene is taken place in a room with only Tatsumi and Mine are there, sitting on a couch discussing Wild Hunt. Tatsumi then brought on the subject of Esdeath coming back which made Mine wonder and say 'when you were captured, or when you got stuck on that deserted island...did...you...did Esdeath do anything perverted to you...?' This caught Tatsumi off guard and he spat out his drink. Tatsumi then denied that she did but did say that Esdeath kissed him, insinuating that she did, in fact, do a perverted thing. Mine was about to cry of sadness but she then says that she doesn't know how many times Esdeath kissed him, she'll make him forget about her. This made Tatsumi blush and think back to when Mine confessed to him. Thinking that Mine was right, and when they kissed, he believed that he was falling head of heels for her.
Back where the Wild Hunt were, a huge tube was placed in the middle of the room with Cosmina inside, naked. Syura then asked Dorothea how she was doing and she responded with her being okay, also telling that Cosmina survived a fire in the past but her family was killed which turned her insane. Syura didn't really care about the backstory and said that 'as long as she's useful in battle, I don't care if she's completely retarded'.
