Bitch, this demon's for you

Within this vessel reside four unrelenting demons devoid of discrimination or animosity; their singular purpose is to bring death. They remain silent, impervious to human sentiments and vulnerabilities, executing what they deem imperative without hesitation. Should you lack the readiness to wield their unparalleled power, acquiring this vessel is ill-advised. While they refrain from harming companions or children, all others are considered fair prey. They hold no regard for household regulations when deeming a person's demise necessary, thus caution is warranted. Their exclusion from the OMG category is owed to the vessel's deceivingly endearing exterior.
