Tsukimonogatari - Episode 4 - Yotsugi Idol Project
A college club's project was a shikigami. No different than manufacturing a performing idol, right?
Araragi's moonlight adventure (see what I did there? moon story? see it?) ends up not being about him turning into a vampire at all, but another plot by Ougi to "correct" the aberrations in the town. Except now we know the purpose - to separate the aberrations from Araragi because he will do whatever he can to keep them in existence. All the story arcs were about Araragi all along. I applaud how all the plots are interwoven in an obvious but still complicated way.
