Merry Nightmare(メリー・ナイトメア)/YUMEKUI MERRY(夢喰いメリー)

As usual, lazily made.

Tail-ish thing might be related to "coat" or "labcoat".

use "striped thighhighs" "navel" "belt" for better results.

Quite an impressive character, I think.

Despite being one of the protagonists, usable full body images are scarce.
