Mystery Moon has a later job that coincides with her name. Changing it to Luna to make it simpler is understandable, but it would not gel with her interests later. IMO anyway, but up to translators decision.
@saudagarbeta did not know that, just assumed that Mystery Moon was a poorly done TL and that she deserved a normal-ish name like the others. Thanks for letting me know!
Not that I'm gonna be doing any more of these though, most likely
Some of these powers are very... eh. Maybe they’ll get more later. A photographic memory? Her books are only temporary? Able to copy animal cries? Not able to speak to em though. I’ll stick to magneto witch, thanks.
