Of all the issues discussed in localizations, characters’ names are often the most contentious issue. Hyperdimension Neptunia has had just about every possible different style of name change across its history: different name but same meaning, direct romanization, and even completely made up replacements.
An aspect of localization that’s often hard to grasp is that sometimes wording has to change for the meaning to stay the same, but sometimes things are changed for other reasons (or worse, no reason).
What was changed, and why?
Arfoire ← マジェコンヌ (majekon’nu, romanized “Magiquone”)
Probably the most well known of the name changes. Her Japanese name is taken from a DS flashcart sold in Japan called Majikon. Her English name is taken from the R4 flashcart (which is essentially its Western counterpart), and also happens to fit more in line with the French-style naming.
