Originally an F/GOCraft Essence released during Halloween showing Mash Kyrielight in skimpy, wolf-inspired, revealing clothes with a fur trim. The outfit immediately caught on inspiring artists to draw other Fate characters in the costume and official merchandise like figures to be made of Mash replicating the card art. Due to the enormous popularity it has become commonplace to draw many characters in the "Dangerous Beast" (デンジャラス・ビースト) tag regardless of their connection to the series.
