You see, I went to Japan where they are originally sold and could have hardly find any of them, if only I went to Taiwan.... xD
I wrote on this company's Face Book profile to check of they even know that Love-chan is protected by copyright (just out of curiosity). At first they replied that they were inspired by Otsuka Ai and other japanese artists and how awesome she is, etc, etc.
However, some person asked bluntly: did they buy the rights or not? (as if it wasn't obvious, but I'm pretty sure not a single person is familiarized with Ai so they didn't have to know).
Again, I replied that I was sure they had no idea what they are selling and now I got a looong PM about how they really didn't know and that I should check their other stuff and point to anything that may also be copyrighted, haha.
Don't take it too seriously, I'm not gonna haunt them because of that. I was just truly shocked since Love-chan is totally unknown in my country (even Ayupan would be, I'm sure) and finding it in our store was like winning a lotery
