The official website for Flex Comix's free web manga site COMIC Meteor confirmed today that TOBI's school comedy manga Omaera Zenin Mendokusai! (You are all annoying!) will get its live-action film adaptation within this year. Its cast and staff members will be announced at a later date.
The manga has been serialized on the site since January 2014 and currently seven tankobon volumes are available from Holp Shuppan. The story centers on Kunihiko Kunitachi, a high school teacher of Japanese, who is, as the title suggests, always swayed by his female students, such as Kazumi Ichinomiya (the girl on the first volume cover) who tires to be his friend for some reason.

in FlexComix Blood) was previously adapted into a four-episode OVA in 2010.
