I hated it before watching the anime (was one of the reasons why started late to watch it), but now I think it fits Viktoriya personality pretty well... dunno why's that.
Youjo Senki's artstyle in general really baffles me because I like it... and I have no clue why. Like, every time I see it, I think, "You know, this really SHOULD be ugly as sin, but for some reason, it actually looks good."
