Leni Milchstraße is the 15-year-old German girl who was part of the project “wunderkind” to create high spirit powered children. She is distant and tomboyish, causing most of the members of Hanagumi to first think she is a boy. She is a gifted ballerina who is named after Leni Riefenstahl, a famous German filmmaker known for his work, “Triumph of the Will”.
Cute cosplay, probably from the same group as Maria Tachibana’s. I wish I could have seen more of Leni in the series. Her developing friendship with Iris is quite interesting.
