|......It was a scene that should have only been Halloween exclusive.
At first, Chernobog was just supposed to cast the character of "Dark Lord", the role he was born with. His existence was informed by his friend who frequented Aoyama Academy to an enthusiastic performer, who then asked him urgently to play.
Taromaiti called such casting "old-school and non-sense" and gave him the exact opposite role "The Brave"; she is not exactly a fan of "stereotypes" like "one would be best to play the dark lord if born as one". This provokes her memories of the values given to her by the person referred to as a "Dark Lord", whom she looked up to, from her homeland.
Due to the tricks pulled out by fairies that did not want the party to end, the enclosed "theater" has been transported to "the land of fairies".
The pumpkin fairies worshiped Taromaiti as their "Dark Lord"--giving her the strength to cast one who should be worshiped. Meanwhile, the one who opposed the dark lord--"The Brave" has also been established. In other words, Chernobog, who naively thought that he was just switching a role, has formed a pair with "Dark Lord Taromaiti"--"The Brave Chernobog" is not simply a momentary role anymore.
Chernobog was summoned to Tokyo via the form of "sharing the faith devoted to a certain Dark Lord from Taromaiti's homeland Garothman". For this reason, he is a opponent who makes Taromaiti feel nostalgic and familiar.
