Record (NJ05) is the Agency's best scout. This flower unit used to be a indie idol, doing multiple shows before seemingly disappearing off the face of the earth. They cut their hair, switched from a CeVio to a VOCALOID4, then started working as a service bot.

You can imagine their employers were confused with a synth android joining their forces, but they were actually really good with people and worked in a hotel as a receptionist for around 2 and a half years.

Around the time The Order was sent out Record found refuge in a building, masterfully hiding from the company. During their 2 year time of hiding in the building, they rigged themself to become an Unassigned NEO in order to not attract suspicion.

Apple (J6N5) is one of the founding members of the VBRA. A original V2 model, Apple is a Hatsune Miku, fifth gen.

She was really close with many VOCALOID producers, lending her voice for several popular songs. She helped producers for quite a while before The Order.

Lilly is a console manager, collecting tips from the correspondents and giving them to the scouts. She was previously an Unassigned, now fit with an Eleanor Forte voice bank.

Once upon a whenever, Lilly was found abandoned in an alleyway, where Record found her and took her back to the shelter. Being a new scout, Record panicked, not knowing what to do. Petal helped Record fix her up and turn her on.

Seeing as she was clearly meant for an adult voice bank due to its shape and size, Petal fit her with an Eleanor Forte. Thankfully, Lilly was meant for SynthV voice banks, and absorbed it quickly. Mint soon found out about her coding expertise, which she gained from learning how to modify her code while being in storage for 20 years. She drafted her in as a console operator.

When a vocal synth android is built, they are normally shaped and created with a specific voicebank in mind. Twintails are given to Mikus, more mature figures are given to MEIKOs and KAITOs, physical robot features and headphones are given to Adachi Reís and Uta Utanes, etc.

However, this isn't the case for every vocal synth android.

A Unassigned is any vocal synth android that doesn't have a voicebank assigned to them. Unassigneds are normally prototypes and androids meant for testing and other things like that that the scouts find.

Alternatively, vocal synth androids that have a voicebank assigned to them can become Unassigned after a hard factory reset and/or enough time spent without power. (the timing tends to be loose, but it's like 2-3 decades long) This chance increases if the android was previously an Unassigned.

Although an encounter with an Unassigned is highly unlikely, scouts normally carry voice cartridges, discs and cards (whichever one depends on the model, only older models use the cartridges and discs) meant to be inserted into the Unassigned giving them a voice bank and clearer thoughts, along with a personality.

Unassigneds can be for any vocal synth - VOCALOID, SynthV, UTAU, CeVio, you name it. UTAU Unassigneds are the most common as people can build UTAU Unassigneds themselves for their own homemade voicebanks.
