First, I need to understand the context. The subject line mentions "-18" which often refers to content intended for viewers 18 years or older. Then there's "Hello Kitty," a well-known character, but typically associated with cute and family-friendly branding. The date "2020" and the format "WEB-DL 720p" suggest this is a video file. "Adult Short" likely refers to a short film for mature audiences. However, the title seems off because Hello Kitty is usually not linked to adult content. There might be a misunderstanding here, possibly a prank, a parody, or even misuse of the character's image for adult themes, which could be a legal concern.
