#4: She's so Bad is a chapter of Badman Strikes Back.

Summary

Badman (Shigeki Birkin) muses on how it's natural that he uses a bat to kill, since all he has to do is instinctively aim for the center of his target, but that there's also demand in his jobs for him to knock off heads with a bat.

Back in his story, right around the time he had gotten used to his job, his daughter Charlotte, now an adult, had disappeared.

One day, a video was sent to his phone. The video, titled "Charlotte vs. Bogart", depicted a fight to the death between his daughter, now wearing a costume and wielding a bat, and a large man with a chainsaw. Charlotte throws her bat at Bogart's left leg, and follows it up with a strike to the head, then 21 downward swings.

After watching the video, it took five whole minutes for Birkin to register what he saw, his daughter turned into an unfamiliar, bizarre killer. As time went on, he continued being sent videos of Charlotte's fights, once every few days, but he would get no reply if he tried to contact the sender. She won all of her battles, and had begun going by the name "Bad Girl".

Birkin notes that the one who finally killed her was Travis Touchdown.
