No, we already brought up the predatory nature of real life currency gacha games in beta, and now there's this.

The items are beautiful, I want them, but they will retire and I have no money to spend right now. Even if I had money to spend, why would I spend this much money on retiring items every single month?

Will these items cycle back to the premium shops eventually or are they 100% retired?

Also, this game is marketed towards adults and minors, and encouraging minors to play gacha-style games wouldn't surprise me if it eventually became illegal in many countries.
