she is a rather plumpy version of SCP 1471 who is known as Blue by her master or mistress.
She tries to manifest physically to be there for the person who uses her app.
While she can't be erased once she begins her process, the only known method of getting rid of her in to consume her when she gets a physical body.
She only makes her presence known to those who are of legal age and is non existant to children or teens.
Blue will also consume her friend should they ask but will be very sad about digesting a friend though they will become an instance of SCP 1471 once digested.
