Hayato's friend from his college days and newspaper journalist, Yoshikiri Takuma, ends up trying to kill himself after reading a cursed tome disguised in the form of a mysterious letter planted in his bag from an unknown sender. He seems to have been targeted after getting too close to linking Karasu to the fake cursed tomes.
