Misaka Mikoto and her clones

When they are together like post #6965354 and post #7185630, which tag should be used, multiple persona or clone?

It's not multiple persona; the Mikasas are discrete individuals, not other personalities or forms from an individual separated.

It also feels wrong to tag the latter post clone, given they aren't perfectly identical and have their own character tags.

While they are literally clones, I don't think the tag on Danbooru is a good fit because the Misaka sister artists generally give each clone personhood and they are artistically depicted with slightly different designs or clothes.

There are some clones who are just generic copies, unlike 9982 or 10023, but even then I think adding the tag is unnecessary since people know Misaka Imouto as being distinct from Misaka.

Thanks for the answer. So I'd assume the same would apply to Raiden Shogun like in post #5763174?
