In what seems to be a surprise announcement, the Charlotte staff have announced in their Twitter and Official Website a 4-koma manga of the Charlotte anime series entitled Charlotte the 4-koma: Seishun wo Kakenukero, subtitle translated roughly as 'Overtake your youth'. The manga will be serialized starting from Dengeki G's Comic Vol. 12, which is scheduled to be released on March 30, 2015.
Haruka Komowata, the artist of Angel Beats! the 4-koma, will be returning to illustrate this series, and the writing will be handled by none other than Jun Maeda himself. 4-komas are generally known to be a more comedic and upbeat style of manga, so this will serve as a good introduction to the characters and their personalities and relationships before the anime starts airing.
For those interested, you can pick up Dengeki G's Comic Vol. 12 off of Amazon Japan. Credits to forum member Rabla for bringing our attention to this news.
