Episode 11

Kill the Mad Scientist (マッドサイエンティストを斬る, Maddo Saientisuto o Kiru) is the eleventh episode of the Akame ga Kill! anime.

Plot
Team Stylish carries out their attack on the Night Raid base. Multiple foot soldiers die during the assault. A member named Trooma incapacitates Leone. One of the members named Toby duels Akame. Akame is unable to poison him fatally with her Imperial Arm because his body is mostly machine due to it being installed with multiple weapons. She is eventually able to kill him after he is impaled by Lubbock in an ambush. Meanwhile, Tatsumi fights Kaku, another member of Team Stylish. Tatsumi is shocked to find that he has Sheele's old Imperial Arm known as Extase. The battle is interrupted by Mine, who is also horrified to see Extase in his possession. Mine quickly kills Kaku and safely retrieves Extase. Trooma prepares to ambush Mine, but is attacked by Leone, who had recovered. Leone accidentally kills him with a single blow, which displeases her. After Night Raid regroups, everyone but Tatsumi collapses, having been afflicted with a paralytic poison during the battle. When more foot soldiers move in, a biological Imperial Arm named Susanoo intervenes and dispatches them. Outmatched, Dr. Stylish injects himself with a liquid that turns him into a Danger Beast, and he consumes his remaining men. Tatsumi, Akame and Susanoo fight Dr. Stylish before he is shot by Mine. Akame slashes Dr. Stylish's real body contained within the Danger Beast, killing him. Najenda and a girl observe the aftermath of the battle.
