Kirschwasser is the nickname for the 99-Series Observational Realian experimental test model, built for collecting data. Since the end of the Miltian Conflict, the 99-Series were retired in favor of the newer 100-Series Observational Realian models and may be considered inferior and obsolete. Their existence lost all meaning the moment the 100-Series Prototype, MOMO Mizrahi, was complete.
