Character Details

NOS-tan is represented as a brown-haired woman who wears flamboyant dresses and hats, wears heavy makeup and is almost always frowning. She often wears wigs as part of a disguise to impersonate her rivals. She has stitches on her body akin to SCOPE-tan's, but less noticeable.

She is extremely aggressive and arrogant, as NOS was advertised as being the only OS for the CDC mainframes, having usurped power from KRONOS-kun, only to be defeated by him and SCOPE-tan in battle, and forcibly demoted.
