I haven't watched all the episodes yet, but these two really don't give any fucks about the male characters. well, i doubt any yuri would happen in a shounen anime, but one can only hope.
@elevown only saw this now, sorry!
Nanofate was what really got me into the whole yuri community, so seeing more of these two lovebirds brings back a wave of nostalgia lol. Im still glad we get the bit of nanofate fanart here and there. :D
You can say there is no subtext, but Jirou literally lies about her grades being bad to spend time with Momo, while blushing and fiddling with her ear jacks.
^she is an unsocial person who has a tough time making friends or opening up (as revealed in later chapters concerning her love for music and instruments). Basically she is just awkward with everyone.
Re watched some earlier episodes and Rikka (left girl) definitely has a bit of subtext around her. I actually wouldn't doubt if this pairing does get hinted at in the show.
Touko can have both Yuu & Sayaka. since author has made them enough lovable for us that's why I can support this! these kind of relationship I can support is here only!
