Josephine Mill Morteln is a character from the anime Sweet Reincarnation. She is the older sister of the protagonist, Pastry Mille Morteln. Josephine is depicted as a young girl with a youthful and somewhat childish demeanor, despite being the elder sibling. Her physical appearance includes purple hair that reaches her waist, often styled in a ponytail, and orange eyes.

In terms of personality, Josephine is portrayed as playful and not particularly mature, which aligns with her youthful appearance. She shares a close bond with her younger brother, Pastry, and her mother, Anies Mill Morteln. One of her notable habits is her enjoyment of dressing up Pastry in various outfits, a trait she seems to have inherited from her mother. This habit can make the process of fitting clothes less comfortable for Pastry, but he does not show anger toward her actions, indicating a patient and affectionate relationship between the siblings.

Josephine's role in the story is primarily as a member of Pastry's immediate family. Her interactions are centered around her home life and family dynamics, particularly her playful teasing and activities with her brother. Her motivations appear to be simple and childlike, driven by fun and a close family bond, rather than major plot-driven goals.

Regarding her development, there is limited specific information about a personal character arc. Her abilities are not a focal point in the available information, with her role being more about her familial relationships and personality rather than any notable skills or powers.
