Yes, there is a demi girl flag. Demi girl is a gender identity that falls under the non-binary umbrella. Demi girls identify partially as a girl or woman, but not completely. They may feel a partial connection to femininity, but may also feel other gender identities at the same time. This identity is often confused with being a tomboy or a feminine boy, but it is a distinct gender identity.

The demi girl flag was created in 2014 by a user named “RavenSwain” on the website Tumblr. The flag consists of five horizontal stripes, with a black stripe at the top, followed by a gray stripe, a white stripe, a pink stripe, and a purple stripe at the bottom.
The black stripe represents being agender, or lacking a gender identity. The gray stripe represents being semi-genderless or partially genderless. The white stripe represents being partially aligned with femininity. The pink stripe represents femininity, and the purple stripe represents a mix of masculinity and femininity.
The demi girl flag was designed to represent the complex and nuanced nature of the demi girl identity. It acknowledges that demi girls may feel different levels of connection to different aspects of gender identity, and that this can change over time.
The creation of the demi girl flag has helped to raise awareness and visibility of the demi girl identity. It has provided a symbol for demi girls to use to express their identity and to connect with others who share their experiences.
Like all gender identities, the demi girl identity is valid and deserves respect and recognition. It is important to acknowledge and affirm the identities of all people, regardless of their gender identity.
In conclusion, the demi girl flag was created in 2014 to represent the partially feminine identity of demi girls. It consists of five horizontal stripes, with a black stripe at the top representing being agender, followed by a gray stripe representing being semi-genderless, a white stripe representing being partially aligned with femininity, a pink stripe representing femininity, and a purple stripe representing a mix of masculinity and femininity. The creation of the demi girl flag has helped to raise awareness and visibility of the demi girl identity and has provided a symbol for demi girls to use to express their identity and connect with others who share their experiences.
