Little is known about Tsumuji's physical appearance; however, her personality seems to be that of a person who is highly dedicated to achieving a set goal and is extremely headstrong. This is shown when Hikage describes all the various ways Tsumuji had tried to kill Homura, and that she had been following them around for days. Tsumuji seems to value family greatly, as she sought revenge on Homura for staining her brother's reputation in the Evil Shinobi world.
