What's up with the translation of Angelica and rihyarda's names?
To add a bit more information to this, Angelika is the more traditional German spelling of the name, while Angelica is more often used in English and the Romance languages. Considering the setting's obvious German influence, we decided to go with the former.
Richarda's name in Japanese is リヒャルダ. Phonetically, that might look like it sounds like Rihyarda, but Japanese also uses ヒャ when writing out names like Michael and, notably, Richard in katakana. Considering that Richarda is also already a traditional German name, though rare, that's what we went with.
