Pilot of the Silver Hawk Burst "Legend". Rather then a human pilot, this is an AI terminal that represents Darius itself. The appearance of this terminal is that of a young female human. Ti2 was given a more human-like personality in order to understand the feelings humans. Ti2 is also able to interact with the Silver Hawk with great proficiency, choosing a human form in order to actually pilot the fighter itself. Ti2's name was devised from the legendary hero "Tiat Young" who saved the Darians back then with the Silver Hawk.
