This promotion of Attack on Titan (進撃の巨人; Shingeki no Kyojin) has currently been announced for Japan (Pmang) and EU (Gameforge). En Masse (NA) has not announced anything yet but has hinted before of a cross promotion and this collaboration is likely going to be part of their 6th anniversary month (May) where there is a “mystery item release” slated for weeks 3-5.
This will likely be a time limited tie up (similar to the Sanrio Hello Kitty promotion in 2016).
