PzkwV

is a mec shop owner in SaGa Frontier, and a playable character, but only in T260G's scenario. His home region is Koorong.

Location
PzkwV is located in a very well hidden place, so finding it in a blind playthrough is quite uncommon. Here's how to reach him:
 * pass through the western section of Koorong (the one with two stores selling armor)
 * climb down through the south ladder into the sewers
 * go south east
 * climb down using the north east ladder
 * go down
 * go left
 * climb the ladder
 * enter the weapon store (red door on the left)

Recruitment
If Leonard is in your party during T260G's scenario, PzkwV will reveal to be a great fan of Leonard's work, and asks to join your party.

Trivia

 * According to The Essence of SaGa Frontier, its name is short for Panzerkampfwagen V.
