This is one of the Dagger modification plans I've posted elsewhere. It's similar to the machine used in the sequel to a certain war game's third installment. The kit used is the aforementioned Dagger as the base, combined with the HGUC GM Custom, HGUC GM Cannon II, and HGGBB Gundam Perfect Strike, as well as Build Custom-style joints, and the armament and sub-arms of the Kyoukai Senki.
Because of this setting, I chose decals from the Earth Federation Forces in Char's Counterattack, as well as Albion and 4th Platoon.
