Vier Dreissig (フィーア Fīa?) is a genius physicist who appears to have died some time before the story of Ciconia no Naku Koro ni. She is apparently in charge of a collection of scientists living in a bunker beneath the Earth's surface.
A young genius physicist from AOU Germany who invented the Spiritium High-Efficiency Energy Conversion Technique (Dreissig Conversion). She won the Bernhard Prize in Physics for this achievement. The day before the prize ceremony, she disappeared and two days later her body was found in an incinerator.
Miyo appears as a young blonde woman with peach eyes. She is typically seen in a pink blouse covered with a white lab coat. She wears a yellow cross with a green ribbon on her left breast.
While she was alive, she was apparently an eccentric who focused entirely on research and could not hold a conversation with normal people.
- Dreissig bears a strong resemblance to Miyo Takano, a major character in Higurashi no Naku Koro ni.
- Dreissig's faked death of appearing in an incinerator is reminiscent of how Takano faked her own deaths.
- In German, "Vier Dreissig" translates as "four thirty". Using Japanese naming conventions, this translates to "thirty four", a recurring numerical motif with Miyo Takano.
