Souma
About
The people of the Souma clan were gardeners, so Souma is skilled in making healing herbs and medicines. She uses the Twin Moon Crescents, Sougeppa, as her weapons. They're kind of like miniature sharp crescent-shaped boomerangs that she can throw out. Souma acts as a spy for the group, scouting the area for any of Taishaku-ten's armies who are on their trails.
It's revealed that she and Kendappa-ou are in love with each other.
In final battle Kendappa-ou fought with Souma. Kendappa-ou believed that Souma could not win against Taishaku-ten so she rather kill Souma herself. After mortally wounding Souma, Kendappa-ou committed suicide. Souma wanted to give her blood to Kendappa-ou so she would not die, but Taishaku-ten stopped her from doing so.
