Funikura, Nyx's living staff and notorious naughty tentacle creature of the original Queen's Blade universe. On the fence if this is a concept or a character given it is both a weapon / tool and a creature.

Unfortunately I couldn't get a lot of expression out of its one eye but the AI does surprise at times. I trained on the word staff which I may have to fix since it can confuse the generator and generate a staff separate - especially if the character uses a staff. Beyond that the only bugs would be multiple Funikuras in one image.

Base
funikura, red eye, purple staff, tentacles

Holding Funikura

Naughty mode

Nyx can also be generated straight from the lora but might be better to blend with a purple based Nyx or Queen Blade lora or just what is baked into Illustrious

For Nyx:
n4x, green eyes, long brunette hair, red strapless dress, purple elbow gloves, feathers, garters, purple stockings, red heels, black choker
