Tokiwaka, a double-axe wielding Makai Knight saves Minamoto no Mitsunaka from a Horror called Shuten Douji that no-one has been able to defeat, and he is ordered by Inari to destroy it. Later, he encounters a young woman, Tamagushi, who believes that her husband no longer loves her. Tokiwaka asks Izumi Shikibu about Shuten Douji and she tells him that it only seeks out pregnant women. One night, the Horror follows and attacks a young woman, and Tokiwaka manages to wound it without using his armour. Tokiwaka then confides in Tamagushi that his armor is cursed and prevents him from ageing. When he removes it, he sees a golden butterfly signifying the time he lost and becomes years younger. He also reveals that her husband, Minamoto no Mitsunaka, still loves her. When the Shuten Douji comes for Tamagushi because it detects that she is pregnant, Tokiwaka must invoke his Makai armor to defeat it.
