Trivia, insights & behind the scenes
The 'brother complex' trope peaked in early 2010s anime, making OniAi a time-capsule of specific era fan service. The light novel industry was basically printing money with this formula.
Minori Chihara (Anastasia) was already famous as Haruhi Suzumiya's Yuki Nagato—cast against type as a bratty aristocrat instead of emotionless alien.
