100-Series

100-Series Observational Units, also referred to as 100-Series Realians, are a subcategory of Observational Realians in the Xenosaga series immediately following the experimental Kirschwasser test bodies. MOMO Mizrahi is a prototype of the 100-Series, preceding each and every mass produced unit as their "older sister".
==Appearance and traits==
As they are designed by the late Joachim Mizrahi, the 100-Series appear as young girls modeled after Mizrahi's late daughter Sakura, but with platinum blue hair and yellow eyes. They are most commonly dressed in light green dress uniforms.
The 100-Series are equipped with powerful sensor arrays, as well as the ability to compute large amounts of data. They are also equipped with the 100-Series System which combines the D.S.S.S. and the Hilbert Effect, allowing them to materialize Gnosis and make them vulnerable. 100-Series Realians, while able to use the Hilbert Effect at small range, are typically paired with a ship's Hilbert amplifier to increase that range. As such, they are often seen on the bridge of ships acting as navigators.
==Story==
Although most of the 100-Series' story relevance is relegated to MOMO, many units are seen throughout the games during both gameplay segments and cutscenes. 
===History===
The 100-Series was originally conceptualized by the late Joachim Mizrahi in an attempt to bring his daughter Sakura back from the dead. To this end, numerous attempts at making a working model went underway onboard Mizrahi's research plant Proto Merkabah, utilizing the data he collected in his work creating the Transgenic Type Realians on Miltia. The failed attempts, referred to as Kirschwassers, continued to live on following the successful creation of MOMO. MOMO, being the 100th attempt at creating this new-model Realian, became the basis for the namesake of the 100-Series.
Following the Miltian Conflict, the Galaxy Federation's newly founded Subcommittee on Close Encounters issued for the mass production of the 100-Series model as an initiative under the umbrella of the Zohar Project. Regardless of any desire to change the appearance of the 100-Series models from a 12-year-old girl, the Contact Subcommittee was ultimately unable to do so, as Mizrahi's design for them was specifically configured for that of a young girl. As a result, the 100-Series' were mass-produced in their originally intended form.Xenosaga I & II , "百式観測器　その２"

One 100-Series of note joins Jin Uzuki in his investigation of the Gnosis terrorism commissioned by the Contact Subcommittee. However, in an unfortunate turn of events, this 100-Series ends up gnosifying during an encounter with a Mysterious Boy who holds a fragment of Lemegeton.
