Thus Spoke Kishibe Rohan

Episode 2: Mutsu-kabe Hill (1x2)

:

Rohan Kishibe narrates to his editor Minoru Kagamari his encounter with a yokai, the Mutsukabezaka. For context, Rohan tells the story of Naoko Osato who accidentally murdered her boyfriend Gunpei. Panicking as her father and her betrothed were approaching her room and Gunpei's wound refused to stop bleeding, Naoko had to resort to drink his spilling blood and in the years afterward took care of Gunpei's corpse. Years later, Rohan meets with Naoko's daughter whom she had with Gunpei, and accidentally murders her. Rohan escapes his fate by making the girl unable to see him, causing the Mutsukabezaka to manifest itself in anger before reviving the girl and make her leave, as the yokai needs a witness when it dies. Rohan leaves safely and with a story for his manga.
