A Deaf Hashashin's Records

"Something strange happened today. My brother, while on patrol, suddenly began walking toward the sea as though possessed. No matter how I shook him, he wouldn't respond. I had to slap him repeatedly before he regained his senses. He later said he heard a beautiful song. When he came to, I was slapping him. Fortunately, I couldn't hear it. But there truly must be a siren song here that enthralls the mind."
