Satsuki is a teenage girl with french pink hair tied long enough to go down to her knees. She wears a big yellow ribbon on the right side of her hair. She also has violet-blue eyes like Moroha Haimura.
Satsuki is very eccentric and she talks fast, and outspoken as well. Satsuki also constantly address Moroha as "nii-sama", and has a tendency to bring up the fact of their connection in their past lives in almost every conversation, especially when Shizuno is with them, despite the latter seems not being bothered by it at all.
She is very self-conscious about her body as she embarrassed by her breast size which is small in comparison to the well endowed Shizuno Urushibara who she compared to in the first episode of the anime series.
Satsuki also dislikes being seen as a weak individual, such as after being beaten by Isurugi, the bully taunted her after her loss, although Moroha still stood up for her, she still ran away in shame and crying. Satsuki brought this fact up again later on when eating lunch with Moroha around
Satsuki set out to find the new incarnation of Kensei and enrolled at Akane Academy to have a better chance at finding him. When she found Moroha, she was hostile to him but soon recognized him as Kensei which made her happy and always attached to him.
Satsuki was once a princess of an unknown land and was apparently the younger sister of Kensei Flaga, one of the past lives of Moroha.
Powers and AbilitiesEdit
Though Satsuki is Rank B, her actual abilities haven't been fully seen in either the manga or anima, but she does appear to be quite skilled as she could summon her prana on her first attempt. Satsuki has shown to be skilled in swordsmanship, but she was still bested by Isurugi in a one-on-one match, though the latter had prior experience in using his prana before entering Akane Academy. She appears to be capable of sensing metaphysicals prior, as first shown when the nine-headed Hydra, a dreadnaught-class attacked them at a mall; the second was when the fortress-class that was nearby on the island they were at for their summer training camp. Moroha mentioned that Satsuki is Power and Tank-Type Fighter rather than a Speed-Type like Haruka.
While the full extent of her abilities hasn't been revealed, in her former life as Sarasha, her older brother, Flaga realized her talent but never allowed her to enter the battlefield thus her talent never bloomed.
