Einhard, pronounced as "Einhart", is a proper German name, albeit for boys. Stratos is presumably a reference to the Lancia Stratos car. This spelling had been confirmed by ViVid anime (episode 5, Blu-ray BOX product name) and The Gears of Destiny media. However, her first name has also been transliterated as "Einhald" in ViVid Strike! and INNOCENT cards, and once as "Einhalt" (German for "interruption") in the Comp Ace magazine.
