The official art of Lu (short for Luanne) that I've not posted yet, now you know what Rep's roommate actually looks like when Rep's not in Snackrifice, drawn n concepted by  DatBlangry!

Lu is a bit of a goth and is 10"5' but doesn't look it without much to show scale, as instead of being tall, she's more just scaled up. She takes up quite a lot of space but she and Rep are very close, Lu using the furniture in strange creative ways to be comfy while Rep can snug up on Lu.
2 examples of this is Lu leaning her upper body on the sofa reading, with Rep resting their head back on her butt and using the backs of Lu's legs as a chair. Also sometimes Rep sleeps in Lu's shirt with breast pillows either side while Lu takes up more than just the bed.
They're both super into vore but before Snackrifice happened, they thought that it was always fatal and also illegal so only emulated it which each other and close friends (plus a ton of teasing).
After Snackrifice's events it's shown that anyone digested in their world causes reality to shift and respawn the next day with a dream of what happened while the pred's memory of the prey fades quickly (unless they know that this happens), as if nothing had happened. This is very freeing to these two who go pretty mad with it along with all the new friends they made during Snackrifice's events
