Regarding the Toriko IF series, I just got another idea that Guilty might try to attempt?

Why don't they create Toriko IF titles from the older series - like the first Shirabe with new voice actor's for the female character if they aren't available.

It's from an older title so maybe the fans, will be a little more reasonable in this situation.

Of course, it depends on how popular the chanter's for the older Toriko titles are...
