I couldn't seem to get a good portrayal of Neco Arc from base Illustrious, so I made a quick Lora.
Standard Look : 1girl, Neco Arc, blonde hair, red eyes, slit pupils, cat ears, ball hands, cat tail, chibi, kawaii, :3, turtleneck, white shirt, blue skirt, pleated skirt, pantyhose, brown footwear,
Base Look: 1girl, Neco Arc, blonde hair, red eyes, slit pupils, cat ears, ball hands, cat tail, chibi, kawaii, :3,
Works well with Euler A and about 30 steps.
