Makes me wonder if that will be the minion included with the Stormblood OST, which is set to be released on July 4, 2018. Product page says it comes with an in-game item code, and OSTs usually have minions attached to them.
I was going to say that there where some data mined music scrolls that where likely for the OST but they've gone directly to the mogshop so the minion as a item code looks likely.
