The new manga series from Ayujo Hatta is titled,
Haibara-kun wa Gokigen Naname (Haibara's in a Bad Mood), and will premiere May 11 in the Bessatsu Margaret shojo manga magazine. Hatta's most popular series to date is the
Wolf Girl & Black Prince title which she began in October 2011 and concluded in May 2016 at 16 serialized volumes. TYO Animations (Terra Formars: Revenge) provided a 12 episode TV anime adaptation of the series in October 2014.
The previous issue of Besatsu teased that Hatta's new series will focus on a high school girl who is treated as her classroom's mascot and her turbulent relationship with a new transfer student. The series will be spotlighted on the May issue's cover and will even have a few color pages.
No word yet on an English translated version of the new series but check back on Anime Mojo for any updates.
