haha well that's mostly true to the gag roots from his canon, tons of anime & manga refs and the like! Oddly he's not even that big into them himself he just knows them all.

Anywho Hayate can cover pretty much any topic given his ridiculously varied job background, so classics of varying degress aren't that far out of his reach if that's a point of interest. more a matter of if he's read/heard them himself over just knowing about them. and arghable I'm too tired to think of actual proper topics but classical music might be a good one over books, since he can play the violin and all?!

hey hey her hair is longer now so at least that's not a super scary similarity anymore
