Bacon sushi, eh? That's certainly new to me, I'll definitely give that a go. Looking at them eat made me hungry, lol. Especially when they were discussing their favourite one (mine's tuna :D).
This seems like Kio Shimoku is planning some Saki-Madarame one-time would be romance in later chapter, well, let's see :) (cause he secretly loves her that's why the got into fight before).
And I guess Saki is pretty otaku-accepting finally.
