Ansemite's Sound of Silence.

According to Tomato Free Novel, I learned the full name of "Learning to Kill Gods in a Mental Hospital", "I Learned to Kill Gods in a Mental Hospital". The piano piece in The Mental Hospital is called "Ansemite's Sound of Silence". The piece, composed by pianist Helmut Newton, is inspired by Anselmites' Sound of Silence and expresses a sense of tranquility and depth. In The Mental Hospital, this piece is used as background music, creating a mysterious and solemn atmosphere.
