These are characters I've had in development for a while and want to come up with a cool story for them. This is just the basics of what I have down.
Star and Ichanna Kunoichi are members of an underground ninja clan known as "Red Moon". The Red moon operates by basically performing jobs that require their skills. The jobs they take on ranges from thieving, to info gathering, to assassinations, etc. One thing to mention though, these ninjas (when out taking on dangerous jobs) often sees a benefit to striking fear into opposition. So if they have to take someone out... the want the next potential victim to witness what they are capable of. One thing Ichanna likes to do, is before she goes in for the kill, she flashes a bit of her sword(Rosè Blade) to catch the enemy's attention, and right before they can even register that the light should taken as a threat and react, Ichanna has already chopped some limbs off. Star (Ichanna's daughter) didn't really take too kindly of this, and took worry into her mother's aggressiveness, as she feared it might make mama go crazy. But Ichanna has always assured that it will never come to that.
The antagonist characters(fighting Ichanna) names are Ivonae Qin Jian(sword), and Tomie Otsuchi(warhammer). They were formal members of the red moon shinobi clan. They were labelled rouge ninja after seeming getting caught murdering one of the eight masters of the clan. Not much is known for their motives, but once it was announced throughout the clan's village and the the remaining masters put out the mission request to hunt them down and bring them back to the clan to answer for their crime against one of their elders, Ichanna jumped at the opportunity. The masters were reluctant to give her the mission for, they were aware that she was (at the time) trainging her daughter Star to become a ninja like herself and didn't want that to get in the way of her training. However, Ichanna insisted they let her be the one to bring them in, and that bringing star along would help with her training, mostly because the deceased member was a good personal friend of Ichanna so she felt it a personal responsibility to bring them the two traitors to justice. The eight masters understood why she wanted to take the mission and inevitably gave her the mission. I might do some more, just gotta think of how I want this to play out.
