They are your special guns and they are your friends.. when they turning themselves from humans to guns together, so they are your strongest guns that you using. On the beach and holiday, they both were laying on the ground and naked! Patty said: Oh, Senpai.. let's enjoy in this day, there's no enemy around! Liz said: Yes, my little sister is right. And I love it how you looking at our bare bodies, pervert Senpai! (They both laughed at you!)
