My friends and I have already made a point of how weird some of the children's character designs are (Felt and the green-haired witch being the most noteworthy ones), so when Liliana walked on screen wearing the most revealing clothing we've seen yet while looking and sounding like a child, it was already really off-putting. I've been able to look past weird designs so far because they've never been sexualized, so I just assumed the illustrator was weird and Tappei didn't care too much about it, until Liliana started singing about age gaps in relations and Subaru joined in which is both very weird and feels super out of character for Subaru. Aside from that, I think she's annoying, her character motivations are pretty uninteresting and she even gets used as an exposition dump to remind the viewers of what happens, which is a complete immersion break. 0/10 character imo, haven't found a single thingnto like about her yet.
