As revealed in Dengeki Magazine, there will be a collaboration with the anime Assassination Classroom . Four of Korosensei's faces will be available as masks (that function as hairstyles), as will Kaede Kayano's and Nagisa Shiota's hairstyles. Additionally, Kunugigaoka Middle School girls' and boys' uniforms will be available as costumes.

A 3DS game of Assassination Classroom will add God Eater missions and costumes. Male characters can put on Lindow's hair and costume, while female characters can put on Alisa's hair and costume. Koro-sensei's Ogretail headgear is also available.
