Tyler's a student at Nazca University, where he works in R&D on UFOs under Professor Yoake. His main goal is pretty ambitious—he wants to be the one who develops Japan's first UFO.
As for his background, Tyler's soul originally comes from the Pleiades, where he apparently served as a white knight before ending up here. It's the kind of detail that either means a lot to him personally or gets brought up whenever his origin comes up in conversation.
