Silent Noise is the eight episode of the Trinity Blood series.
Father Abel Nightroad and Sister Noélle Bor are tasked with investigating the unexplained collapse of the National Palace in Barcelona, only to be told there that the collapse does not seem to be the result of foul-play. They use a break in the investigation to explore the city and enjoy the attractions that it offers; during the course of the day, a drunken Noélle tells Abel that she is in love with him, but he gently rejects her. When the investigation resumes later that evening, Noélle travels to a pharmaceutical company in search of more information; elsewhere, Abel finds the body of Professor Barrie. Isaak Fernand von Kämpfer appears and reveals to Abel the Silent Noise system that was developed by the late professor and is capable of destroying entire cities in moments. He then activates the weapon and destroys much of Barcelona, but Noélle is killed in the devastation. Although Abel is able to destroy the system in his Crusnik form, Isaak escapes.
