Joe was intent on memorizing the names and abilities of each of his comrades, so that he'd be able to formulate better strategies in battle. Just because he wasn't the leader didn't mean that he couldn't also use this information. When he found a space in the introductions, he himself spoke up.  "The names Joe Shimokita.  I'm a mid-range combat specialist," he said summoning his DG-9's above the water, showing off the fact that they were bladed guns, "and I've got the ability to manipulate elements." to demonstrate his point, he sent his guns back into his pocket dimension, and put a hand in the water.  Moments later, a small geyser hit the ceiling of the cave and came back into the water. "And that's not all," he said, adopting a mock tv announcer voice,  "for the low, low price of 19.99, you too can experience the power of a demon sealed inside this young man." He raised his right hand so everyone could get a good look at the seal on his hand. The red eye pulsed in what Joe could tell was annoyance.  Adopting a more ordinary tone he continued, "I'm also quite handy with technology.  I've been assigned the job of modifying that Vickie over there. To differentiate her from other Vickie's I call her Tomo. So far I've only modified her software, and I hope to work on the hardware once I can find an adequate work space, and/or some time to do it. Background wise, I come from the engineered planet of Valka, which has relatively similar technology to your Earth, but lacks most of the resources to develop and build it. Unfortunately, when my ancestors engineered the planet for their experiments, they didn't take into account the possibility that the races they placed on it might actually survive and build a civilization there, so it wasn't meant to sustain them.  Anway, I look forward to working with you all."
