It amuses me that from a chapter that had plenty of great Nana fanservice moments the first page to get a fan coloring is the Tearju's breasts scene. Poor Nana, even after finally getting a chapter about her she is still not loved enough.
We once again get the 'Nana is falling for Rito' line with this chapter so maybe Yabuki is planning on bringing her out of Momo's shadow and giving her more page time in future chapters.
