These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Vanguard Princess
Les Yay: The animation of Kurumi's Liberty Art where she fuses with her assist character. Both Kurumi and whichever assist she's with are showing some Barbie Doll Anatomy and just before Kurumi is transformed they were about to make lip contact.
Moe: All of the assists except for Juliet. Out of the main cast there's Kurumi, or maybe she fits the Cloud Cuckoolander more. Her conversations with Juliet and Eri would suggest so.
