Skill Install
End each of the mission, you'll obtain "Left Behind God Arcs". These will be separated on the following categories depending on what you obtained: Blade, Gun and Shield. When you are in Skill Install menu, you are not viewing the skills but rather the name of that particular Skill Install so make sure to press start to view the skills it has! These skill installs may have more than 1 skill in them which is listed on the 4 boxes bellow the name after the end of each mission (Just like in the picture!). You could install these into one of the four slots of your weapons of that particular category. Be aware that you cannot delete them, you could only install and overwrite it. Each skill has a certain level, if you have another same skill present, the levels will combine (Example: Health Lv 1 + Health Lv 2 = Health Lv 3!). The higher the level, the more better effect it will exhibit (Increase per level on the skill section)
