User blog:Martialmaniac/Kakin Royal Family names

To separate the name and surname of a character, we generally use the "=" symbol: For example, "Gon Freecss" is "ゴン=フリークス". However, between the name and surname of characters from the Kakin Royal Family the symbol used is different. Wouldn't it be better to have the same on all pages? Or is there a specific reason why they're different?
