Trivia
She is heavily inspired by Kuchisake-onna, a Japanese urban legend about a woman who got killed by her husband, a samurai, after the he slit her mouth open because he believed she was cheating on him with other men.

404 also shares some inspiration to Kuchisake-onna, as she wears a surgical mask and carries scissors, just like how Kuchisake-onna is said to appear sometimes at night in the urban areas of Japan.
