Appearance
Sumire is an older woman that wears a habit, which consists of a tunic, covered by a scapular, and a veil, dark shoes and a pendant with a cross-like insignia as a charm.

Personality
From what little seen of Sumire's personality, she was reluctant to allow Hibana to play with her prowess as a Third Generation, showing a cautious, but a compassionate side. Upon her reappearance, Sumire is highly evasive when questioned but will praise somebody for coming to the right conclusion. While she still acts in a warm and friendly manner, she is completely ruthless in her actions. Deciding to kill quickly while acknowledging her target's skills with the same motherly tone.

Abilities
Sumire is powerful Third Generation, whose capable of creating vibrations via the natural human reflex of shivering, which in turn causes every muscle in her body to vibrate in small bursts which, in turn, creates heat and from there she amplifies the heat and transforms it into kinetic energy which she then uses to create even bigger vibrations and by using her Adolla Burst in tandem with her ability she can create even stronger vibrations capable of easily destroying metal and can subdue individuals with physical blows channeled with her vibrations to easily beat them and shake the very earth.

Background
Sumire attended The Holy Sol Temple, where she took care of children such as Hibana and Iris. She also claims to have looked after Rekka Hoshimiya when he was young. One day, when the Human Body Ignition Phenomenon struck the temple, her life, along with the lives of many other sisters attending the temple, was taken by the flames — an event that led to Hibana losing her faith. However unknown to Iris and Hibana, Sumire in truth either survived or faked her death during the phenomenon and seemed to have then gone into hiding for the next decade or so.
