It occured to me that this is the second time that they have animated Kagami in extended "high-quality" detail, the first being the Hiiragi "sisters drama" snippet. Makes me wonder if they will ever animate a spin-off OVA for Kagami in full-blown quality, like a certain submarine Captain.
3D-rendered bugs and cicadas? Gross overkill. Kagami done in KyoAni's highest level of animation? Bring it on.
Cheers.
