For all the twenty-somethings and above out there, there's now (a limited amount of) Boueibu sake. This alcohol comes from each of the boys' local areas (in terms of where their surnames' namesake onsen are). The labels are sparkly, too. They're all junmai sake (made from water, yeast, rice and koji, which is a type of fermented rice), but Io's is junmai nigori sake (contains unfiltered sake lees, giving it a cloudy look) while Ryuu's is karakuchi junmai (has a dry taste to it). The website even says things like what the sake pairs well with (e.g. Atsushi's goes well with oden, yakitori (salty), cheese etc.).
Murakami made collages of the Haikara fanart she's drawn and arranged them by character (except the student council, who get a shared collage).
