Fuguriya has started a video series named Hanahiranime!, a 10-part companion series to Hanahira! in the style of the Reo/Mai Diaries. Unlike the Diaries, it is being posted on Nico Nico Douga, not on their YouTube channel. I will upload them to YouTube myself for convenience unless Fuguriya chooses to do so themselves. Note that the Nico Nico Douga has additional subtitles for the benefit of Japanese viewers.
This playlist collects all episodes on YouTube.
