Senketsu. A medical ninja who enjoys isolation and peace, and completing tasks by himself. Although teamwork is something that is required for completing a multitude of tasks as a ninja, he'd rather find a way to do it alone than have to rely on others. He was forced to mature at a young age. He lived alone for the majority of his life, given that his family was killed by bandits at a young age. Luckily, the bandits didn't kill him. He realized that depending on others could very well result in his own demise, after what happened with his family. Senketsu strives to become a ninja who is able to defend himself without the help of others.
