Mari is an Earth Art using Taimanin of Gosha Academy. As she is still mastering her earth manipulation ability, she is rather clumsy and insecure, which holds her up in classes. Mari has already been on many missions and has proven herself as one of the stronger Taimanin of Gosha Village but often still only shines as a supporter, as she lacks confidence. On some missions, she is seen with a group of Earth Art Ninjas and displayed leadership skills. She is in the same class as Mizuki Yukikaze, being the class' representative and is well liked and often keeps the class peace. Together with Nanase Mai she often reads books and the two often go on the same missions.
