Marina caught the gutar and stumbled backwards a bit before regaining her balance. "Don't worry, Haruko. This'll only take a second!" She put Haruko's guitar in both hands and started shaking it, up and down. within a few seconds, it started to glow yellow. The changes that followed were obvious. The guitar got a new polish and the innermechanisms that allowed the guitar to fire rockets and bullets and the such became more powerful, allowing for faster and farther shots. The projectiles also became more powerful, the bullets would pierce more smoothly and the rockets would explode more violently. The physical changes were shown in that the guitar seemed to extend it's edges a bit and become more sleek in appearance in form. It was brand new and badass, more powerful in everyway. And in return to Marina, it spit out a few blue crystals which her body immediatly absorbed. "Here, try that!" Marina said, tossing the gguitar back to Haruko.
