So, what should we do about Usagiyama Rumi's case? I'm pretty sure her hero name "Mirko" is more popular and used than her real name.
In her case, Mirko is definitely the way to go, just from that tag having 4 times more images on pixiv. And, as you said of course, it's the more popular name.
To take the conversation a bit further though, to make searching easier we will need to make more aliases/implications into the "popular name".
Since we'd pretty much be going with a mix of the Fate character tagging system (1 main popular name, real name in description and aliased) for heroes/villains and the Precure character tagging system (2 or more character tags, 1 for the 'real name' + 1 for each of the costume persona) for the students/mostly civilians.
