She wasn't only offered a trip to Japan- she now lives there and is used in commercials and such. She is an icon in Japan, she was also the most subscribed person on Youtube in Japan.
I've liked Magibon for years- I have no problem with her. I personally think she is adorable, even with her horrible teeth.
There's a lot of hate over her but she's just a girl with a fascination with Japan and dramas- I see those everyday and they don't get insulted. It's just because she got some popularity from being a Japanophile.
