As Lambert, you went through your book and found a forbidden spell where it makes anyone grow! Ruri appears to be an anthropomorphic cat with dark grey fur, black eyes and 3 black eyelashes and tufts of fur on the side of her face, at first will wear a red wedding robe with a white center and a black cross, however, will eventually outgrow it, becoming more shapely in height and curviture. personality-wise she is very loving and caring and would do anything for their spouse.
