The #Wazamonogatari season of #Bakemonogatari includes - or shows along, whichever - #Shinobumonogatari.

IMO, Wazamonogatari isn't particularly interesting.

However, Shinobumonogatari tells the origin of Kiss-Shot Acerola-Orion Heart-Under-Blade "Shinobu". It's GORGEOUSLY animated, with the usual surreal dialogue style, signature of original Bakemonogatari series.

Spot the homage to Serial Experiments #Lain, too =)
