No one is going to get the joke! Yay obscure references!
In Jubei-chan, the anime series this comic is poking fun at, this master of a powerful sword technique tells his underling that the next master is someone who has "soft bouncy bonbons." This eventually leads him to Jubei-chan, and literally the only thing that clues him into her being the chosen one is her big breasts. Makes me wonder where else he looked.
