I actually think that that’s what makes it funny; the fact that it could have not used Little Busters as its medium and would still be entertaining. Really, with this sort of thing, the only way you can make it related to the original and still entertaining is if you make cheap shots at the show, which I feel would be in bad taste.
There was the “You mean Kud? But she’s like 10!
That’s never stopped me before” which I feel is a reference to Loli Loli Hunters
