One of the most surprising trends to come out of 2017 was the rise of yuri manga. We saw not only more new titles, but also more publishers taking a chance on it. It's safe to say that no one pushed the boundaries of yuri more than Yen Press with this series, though.
MURCIELAGO, by Yoshimurakana. First published in 2013 and first published in North America in 2017.
PLOT:
Kuroko Koumori is a vicious killer with over 700 victims to her name. Instead of execution, she is given a new job: to kill any criminal deemed too dangerous or too strange for the police. With her cutesy assistant Hanako, she'll take on everything from a drugged-up killer wrestler to a couple of wanna-be robbers to a murder mansion full of traps and other career criminals like herself, all while hitting on every pretty girl she sees.
