This is not really my usual forte, I haven't even seen the thing, just thought that the character design was interesting.

Anyhow get her with those prompts

llennbase, brown hair, brown eyes, short hair, animal hat, pink headwear, 

And the suit

fur-trimmed gloves, pink jacket, long sleeves, pink pants, cross-laced footwear, rabbit hat, elbow pads, knee pads,

Lastly you can add those to get her personalized FN P90

holding gun, p-chan, p90 submachine gun,
