The tag alias #59262 nickii_katana -> teni_kolahoi is pending approval.

Reason: Character had a name change, now goes by teni_kolahoi

It's always good to provide proof. Though in this case, it seems nickii_katana isn't used and has never been used.

Nickii Katana appears to be an earlier persona of artist Katanagirl, used as recently as 2021, but Teni Kolahoi looks to be the artist's current persona. A cursory look through their gallery or Twitter doesn't reveal any direct acknowledgement of a change. The two personas also have a few differences between their designs. It may be best to just leave this alone and possibly treat the older persona as now being a separate original character.
