BUR #22381 has been approved by @nonamethanks.
create alias osage_(inabakumori) -> osage_(nukunuku_nigirimeshi)
I want to propose a change to Osage's name for the fact that the character predates her use in Inabakumori's music videos and started out as an original character of Nukunuku Nigirimeshi (illustrator for his music videos/albums). Additionally Pixiv and Twitter both use the Osage-chan tag for her (which literally translates to pigtails-chan, since she doesn't officially have a name). And some of the official artwork she appears in such as post #7080769 and post #6527924 for example are not directly related to any Inabakumori songs nor use the iconic Black and White sketch drawing art style that is commonly associated with his music videos.

Pixiv Tag (おさげちゃん)
The character also has her own 4koma webcomic drawn by Nukunuku Nigirimeshi which is unrelated to Inabakumori.
In case this update goes through, I think the Inabakumori copyright tag should be kept just for the fact that the character has become way too associated with the music artist to be classified as original, not to mention removing the tag would probably make things messy. Feel free to disagree, though, I'd like to hear opinions first.
