As Masayoshi is left with many questions about Haiji, he receives a call from him whilst staying in a hotel, explaining how he became obsessed with him after witnessing his earliest superhero efforts, deciding he wanted to become his arch nemesis dedicated to doing bad things to Samurai Flamenco. Masayoshi becomes further confused when he hears from the police that Haiji Sawada allegedly died from illness one year ago. The next day, after Haiji tells Masayoshi he intends to do something 'colorful', malicious things are done to the Flamengers, with Jun being pushed down the stairs and Joji being hit by a truck. After receiving more threats from Haiji, Masayoshi meets up with Hidenori, who offers little comfort and even becomes angry when he brings up her missing girlfriend. Upon realising that the only one who has seen or heard Haiji is himself, Masayoshi starts to wonder if he is just imagining him.
