The story takes place as a girl explains that she is not responsible for the death of her father and that it was another her. Suffering from Hereditary Evil Raiser Syndrome, the girl insists that she loved her father and always watched him as he worked and obeyed him when she was told not to touch the switch. However, the other her came out and pressed the switch instead. As the song progresses, the medical journal by the doctors watching her is displayed, along with the girl's personal diary. At the end of the song, she begs not to be given the injection, saying that she doesn't want it.

The song's title contains the characters for the Japanese word 血みどろ (chimidoro); aside from meaning "bloodstained", the word also means "desperate" or "frantic", referring to the girl's struggle against her HER-infected alter.
The word "switch" is a play on words, referring to both the physical switch and the girl's "switch" between alters.
Because there were no ties period-wise to his other existing songs during that time, mothy purposefully chose the default outfit for MAYU as the design for the character.
The doctors' medical journal mentions Dissociative Identity Disorder, a real-life mental disorder characterized by the development of 'alters', or multiple distinct identities.
