Shigu is Another close friend of Funco. She is a Swiss SG 550 assault rifle. Her grades are top notch and she's an honor student, but a bit out of it at times. She sports exceptional firing accuracy at mid-range, and doesn't like to lose. She appears to have feelings for Funco and gets jealous when others get close to her.
Developed in Switzerland, she's designed as a marksman rifle for long range fight. She can hit a target at 700m, because Switzerland is full of mountains. She's more effective with the semi-automatic shots, but she also can select burst or full auto.
