CG Midlander

[Soukyuu]

Some have theorized that the Midlander takes over the body of a fourth party member, and witnesses what that person saw. While an interesting theory, this, unfortunately, is not how the Echo works. There may have been a fourth member around earlier, but he was gone by the time the Midlander arrived (probably returned to his home point after getting KO’d and accidentally dropping his bow).

Just something I noticed after rewatching the opening: The bow belongs to the Midlander, when he drops into the lake on arrival, you see him holding a bow. So in the Echo, he was an archer.
