Also known as: BB1st, ビィビィファースト
Originally BB (Fate)'s first character design as EXTRA's boss, which got scrapped and appeared in the Fate/EXTRA material book (asset #23869591). It was later repurposed for Fate/EXTRA CCC Fox Tail's "BB1st".
BB1st isn't actually BB, but Meltryllis (Fate) disguised as her after becoming Kazuradrop (Fate)'s puppet.
