Mio appears to be a very aggressive and angry person, but it's unclear if this is her normal personality or because of her extreme hatred of Sasa Yuuki.
Mio's backstory is unknown. All that is known about her is that she was apart of Lina's group in Kazamino and has been fighting against Sasa for a time with them, seeking to avenge the death of her best friend Futaba who was killed by her.
During Sadness Prayer
Mio is first seen helping Lina and the other members of her team fight against Sasa in Kazamino. After Sasa escapes, Mio tracks her down and fights the other magical girl by herself against Lina's orders. It is revealed that Sasa killed a member of Mio's team named Futaba, who was Mio's best friend. After Sasa insults the late Futaba, Mio becomes infuriated and deliberately tries to kill Sasa. Before she has a chance to she is killed by Kirika who appears out of nowhere.
Her body is later found by the group with Lina blaming herself for not taking into account that Mio's hatred towards Sasa would push her to fight alone and get killed.
She is seen shooting a chain from her weapon, which she used to wrap around the wings of Sasa's Witch and pull her self up to Sasa's height to attack her.
- Like Futaba it's unknown if her name is either her first or last one.
