I don't know much about canon Haikyuu Quest either so I can't help there.

I don't think there's a lot of gen memes up, but I'd like all three of those (even if the third one sounds like it'll be a disaster). Akaashi and Bokuto having lunch together for Fukurodani maybe? And I dunno for Kuroo and Bokuto I feel like they'd just try to outdo each other a lot no matter what they do, even if it's a noncompetitive thing like watching a movie.
