I have completed the modifications to the Helmwige Linker that I posted about previously.
It is based on the Helmwige Linker, but the setting is that it is a Gundam frame.
The head and legs have been replaced with Rubrisuul and Thorn, the backpack is equipped with a Demi-Birding, and the sub-arms are reused from the General Fortress.
The setting is that it is a Gundam frame MS named after the Devil Bune, a special machine equipped with a huge sub-arm, which was reused from a destroyed mobile armor.
The setting for the sub-arm is based on the mobile armor described above,
