Prunechi should be revised and renamed. I remember creating it, right after I thought I found out the character's name, but can't recall how I came up with it. After recently seeing many art with the character's name, it's think it's time to correct it, but kinda unsure which name or copyright tag to use.
In Korean her name is 빘치 as seen on post #5865672, post #6670094, post #6811199 and post #6811331. Some help with romanization could be enough. However, in English, her name seems to be "Bittch" as in post #6752656. This last one by Retri is similar to other commissioned works which have the character's name on them. Moreover, both names are also the username of the commissioner as seen on the Kakao URL in their profile and discussed in forum #248744.
Another thing is the copyright tag. I don't really know much about the game, but afaik "Prunechi" is a custom character of the Lyn race from Blade & Soul. Should those tags also be added? Or should "prunechi" be kept as an original character? Some early art under prunechi has BnS and Lyn's tag, and some in Pixiv have a BnS tag but not a Lyn tag. Searching for "린검사" or "Lyn" on that site yield no results of "prunechi", but those under "린녀" resemble her.
