>Michiru
It's actually Mytyl, that wasn't a localization change. "Michiru" in this instance is a Japanified version of it. There's a bunch of references to "The Blue Bird", the play where the name originated, in GV2.
It confused me too because "Michiru" is also just a regular ass Japanese girl's name, but I assure you I'm telling the truth.
As to why Acura isn't named "Tytyl", that's because Shinobu was hellbent on naming her boy after her highschool girl crush.
