As Hikaru, she is also a founder and captain of Kaiho. If Hikaru is the best warrior in the army when it comes to close quarters combat, Sora is the best when it comes to long range encounters. Her accuracy with the bow has been regarded as inhuman since she was a child.
Although she can defend herself with a sword, she is far more comfortable keeping some distance between her and her opponents. In order to do this, Sora is capable of instantly traveling to different light sources while she flanks her targets. If you must face her, don’t let her flank you or you will be turned into an archery target in no time.
