I judge the comfiness of your head!

[Amaterasu]

Viola: Hmm, let's see here keptic:
Well, the adorableness doesn't per say count but I can see her taking special care of her hair, so that's a plus point. The twin tails, Iunno. It depends on how much Viola pulls her hair into pigtails, thus leaving less for cushioning the top surface. Also, the heterochromia eyes and overall looks are very anime, so that's an extra point! On the other hand, her underage-ness means that the overall head surface is a bit smaller than those of most hattable humans, and if she's 13 I'd give her a mildly heightened risk of being the sort of kid that does evil things to dogs for fun, like attaching a can to their tail or pretending to throw a ball and then not actually throwing it :frog: So I'll substract... let's say half a point for each.
The total comes down to 6/10. This will scale up to 6,5 in let's say 4 years, and in 6 years you'll have 7.

EDIT: I was informed that not only does Viola not do evil things to doges, but also that her twintails would make for great scarves for fashionable hatters, so I'm upping her points to 7,5 (scaling up to 8 in 6 years)
