Hi there! I'm the original designer, though I go by a different name on deviant (where I'm goudachizu). In this account I'll sometimes do collabs with a friend, so the nick's different.
I'll use this account's nick next time as a watermark
I posted it on another account on deviant by the name of TsukichiiExpress, an alt account since I don't plan on using my og for adoptables. But another user here messaged my account on deviant to confirm it's legit.
Sorry for the confusion
