Accessory Unlocked but I can't find it?

So today I decided to try unlocking the Mikudayo Mini accessory by doing that thing in Miku Miku ni Shite Ageru where I have to get 39 safes, sads, fines, or worsts. Basically what I did was play it on Hard, put on the help item Recovery, missed the first 6 notes then missed the whole first technical zone to get 39 worsts. Now, I had to retry a lot of times. Sometimes in the middle of the song, sometimes at the very beginning, and twice after I finished the song because I ended up getting 41 instead of 39 (damn you chance time).

The thing is, when I did get 39 worsts finally, it didn't say that anything was unlocked. So I was like "what" and checked that board where it shows what you have and haven't unlocked for the song, and it did say that Mikudayo Mini was unlocked. So I went to the shop and checked all the accessory categories, but I can't find anything related to Mikudayo. What happened? Where did the accessory go? Or is it not Mikudayo at all and the guide made a mistake?

 

^ Yeah, I made sure I got 39 worsts and I cleared with a Standard.

Edit: Wait... Is the mini mikudayo thing something from F or is it something new in F 2nd? Because I already transferred everything I had from F. So I made myself suffer over the 39 notes thing for no reason... I thought it was greyed out when I checked it in the board before attempting to unlock it!

 

I only realized this because I was going to buy the mini top hat accessory for Miracle Paint to unlock something else but it wasn't there either. So I was like "wait a minute..." and checked the accessories I already did have. Stupid me. This thread can be locked/deleted.
