Araya Kimura.
She was what you know as a 'triple-threat'. She was a skilled mercenary, but also a silent ninja and a well-known ronin. The only reason why being a ronin was a threat was because when switching between armies, you learn everyone's strengths and weaknesses, which can be easily used against anyone in battle. She'd fought for practically every army, from the Date to the Tokugawa, from the Hōjō to the Toyotomi. Even the Oda, while they existed, for a very short while. While fighting for different armies, she trained under Magoichi Saika and the ninjas of Iga, including Hanzō Hattori, her cousin, which perfected her skills as a mercenary and ninja.
She had pure, black hair, creamy, smooth skin and bright emerald eyes. She had the perfect figure for a ninja, even though she was reasonably tall. Her weapons consisted of a pair of twin sai blades, a collection of shruikens and serrated-edge throwing knives. They were all coloured midnight blue, with silver edges. Her war attire was the same colour scheme. It was inspired by Lady Nene's, after a random battle while discussing something. It consisted of the same dark blue leotard-like suit, silver leg straps, similarly coloured skintight boots and the same colour mask. The leotard had silver stitching, and all the silver items had midnight blue.
All in all, she was a great, natural beauty, but all of the men that she worked with were always too intimidated to tell her any such thing in case she didn't like it and threatened them or did something, bad, to them instead. Same with the girls, but instead of telling her how beautiful she was, they settled for envious glances at her when she wasn't looking; equally afraid of her wrath. This led her to be a quite intimidating person, but with surprisingly quite a few loyal friends, and the ones she did have were ones she knew she could trust with her life. If you weren't her friend, then she comes across as intimidating and reserved, but if you were then you knew that she could be sly, but playful and caring at the same time. Surprisingly, most came from the Tokugawa like Tadakatsu Honda and Ina. Tadakatsu and Araya had met out of mutual respect in one another's abilities while she was working for the Tokugawa. The same happened with Ina, once Tadakatsu introduced her to Araya after a different battle. Araya was also friends with a girl named Kai, who was part of the Hōjō. She and Kai had met while on a mission with each other, but trapped in a dilapidated castle. Kai's overflowing confidence and innocence drew Araya to her and Araya just loved to tease the younger girl about her obvious attraction to Magoichi Saika and Yukimura Sanada.
Her friends in the Toyotomi consisted of Kiyomasa Katō, Nene and her twin Raiden Kimura. Like his name suggests, his war weapon and attire revolve around thunder and lightning, with his sword being a bright golden colour, shaped like a thunderbolt. Similar to Ginchiyo Tachibana's weapon of choice. Back on the topic of friends, a man named Mitsunari Ishida was also part of the Toyotomi ranks, before Hideyoshi Toyotomi died and the Toyotomi became the Ishida Coalition after clashing with Ieyasu Tokugawa endlessly. Mitsunari Ishida was more like an acquaintance than a friend before this, though, as during the brief times with her working with the Toyotomi he was extremely self-absorbed and arrogant. The few times he had spoken with her had left her fuming and irritated afterwards at his overly-sarcastic self. Even she wasn't that bad.
