Sparkatale

Sanae Hikari is an ordinary high school student until one day she stumbles across a mystical artifact and is transformed into the magical girl White Star. With the help of her familiar, a youkai named Kousen, she battles monsters that threaten her hometown of Mitsuzawa, as well as a more villainous magical girl - who is secretly her best friend, Amaya Kurozawa. An irreverent parody of the "magical girl" and "slice-of-life" genres. Contains mild language, violence, and suggestive themes.
