"Little Red Riding Hood" of the series.
Lisette is a childhood friend of Wilhelm. She always wanted a red-colored hood, but her family could only afford a grey one. Lisette did not like Ludwig at all and felt that he would always hog Wilhelm from her. She wanted Wilhelm all to herself. Ludwig happens to overhear her talking to herself in the forest and decides to play a trick on her.
Lisette's mother sends tells her to take wine and cake to her grandmother’s house. Beforehand Ludwig switched the road signs so Lisette winds up in an old, burned house instead of her grandmother's house. The house was actually owned by a woman with no family but was killed when her house and set on fire by Hansel and Gretel. Lisette really does think that it is her grandmother's house and is horrified when she finds a corpse inside. Ludwig disguises himself as a wolf demon and tells Lisette that just like her grandmother she was sent as a sacrifice by her parents, in exchange they would get a pile of gold. She runs home to see if this really is true. Meanwhile, her parents are waiting for her back home. They’ve prepared a special dinner and were surprised when they found a pile of gold outside their cottage. Lisette comes home and brutally murders her parents with an ax, believing what the wolf demon said to her. Wilhelm hears screams and rushes to the cottage. Inside he finds Lisette covered in blood and her dead parents beside her. She goes crazy and goes for Wilhelm but Ludwig saves him. After that Lisette disappears never to be seen again. In the end she did, however, get the red hood she wished for even if it was dyed with fresh blood.
Several years later we see Lisette again. She's now known as "Little Red Riding Hood". She’s become an assassin and a wanted criminal. This time she's after Prince Ludwig and won‘t rest until he‘s dead. She despises Ludwig ever since the incident and blames him for the fact that she now enjoys killing.
