Well, the talk about Futaba made me:

1.) want to have a Toriko entry where we have a grown up Futaba as a returning character - she lost her virginity at the end of Shimai's "good ending", so I think it's possible for her to make a comeback.

2.) Another Shimai type Toriko game, where it's required for everyone to lose their virginities, in order to achieve the "good ending".
