Shakalaka Prized Bow

Prized possession, the old design has been modified to support Rapid Fire Dragon S.
A light bowgun the Shakalakas made by putting together things they found around them. Through countless improvements, at some point it became able to rapid-fire Dragon S. It is a treasured bowgun of the Shakalakas, and very few know how it is made, a method said to use ancient relics.
