Episode 12

Kill the Newcomers (新入りを斬る, Shiniri o Kiru) is the twelfth episode of the Akame ga Kill! anime.

Plot
After Dr. Stylish's death, Night Raid ventures into a Danger Beast infested area so they can set up their new hideout. Najenda introduces Susanoo and Chelsea. Chelsea is the girl from the previous episode. After their introduction, Chelsea berates Night Raid for their incompetence, which she alleges led to Sheele and Bulat's deaths. Angered, Mine decides to teach Chelsea a lesson and recruits Lubbock and Tatsumi. Tatsumi uses Incursio to sneak on the hot spring where Chelsea is bathing. However, Tatsumi instead confronts Susanoo. Susanoo is actually Chelsea using her Imperial Arm known as Gaea Foundation that changes her physical appearance. Chelsea tells her story about her former team being massacred. This leaves her as the only survivor. She reveals that she berated Night Raid because she did not want them to die as her former team did. Meanwhile, a depressed Esdeath learns of the loss of Dr. Stylish and comforts Seryu when she grieves his death. At the Capital, Run tells Esdeath there are many lookalikes of Tatsumi for her to court. Esdeath declares there is only one Tatsumi. At the mining caves, mysterious Danger Beasts devours the miners.
