Lily is a very shy little girl. She tends to keep to herself, and almost never wants to be the first to meet new people. Despite this, she is a very good weapon and warrior on her own, never wavering from a mission with her sister and wielder.
Lily, in contrast to her sister, is very much like her mother. Both are very hyper, love when people are in love, and are also very dirty minded. The only major difference between mother and daughter is that Lily tries to be innocent while Rosenrot is just straightforward with her thoughts.
Lily and Dahlia are constantly in competition for being Jasper's favorite weapon, and have even been fighting since they were in the womb. Despite this, they care about each other very much, and can actually telepathically communicate with each other on a level that almost nobody can intercept.
