^People like what they like. Another ayu-mi-x would be fine too. You don't get it. It's like asking for a peanut butter and jelly sandwich with grape jelly, but you receive it with strawberry jelly. According to your logic, it's still a peanut butter and jelly sandwich, right? Nahhhh son.

ayu herself isn't "fashionable" in Japan right now either, if you haven't noticed. It doesn't matter what's fashionable, if enough fans out there desire a certain product, there is a higher chance of that product being released.
