Ramirez. If you're not too busy with slaying the creatures running around on the surface, I'd request that you return to headquarters immediately: I've a minor operation on my hands that I was wondering whether you'd like to partake in. It involves world-jumping, and fetching a sample of poison mist for the laboratories from a young lady named Sheena Fujibayashi. Sound like something you'd be willing to attend to?
It would be a good opportunity to look over your scratch, as well.
