Tokugawa Sen

Profile
Tokugawa Sen (徳川　千) is the princess of the original Tokugawa House that ruled Mikawa. Because she greatly enjoyed fighting, she was nicknamed "Princess Battle" ("戦姫", pronounced as "senhime", which is the same as "千姫" or "Princess Sen"). She sometimes has to correct people because "sen" can also mean "thousand".

When the Youkai racoon dogs conquered Mikawa and took over the Tokugawa House, forcing all humans to serve them, Sen refused to obey and kept fighting to the bitter end. Out of fear against her, the racoon dogs locked her up in the Mikawa dungeon. At one point, Sen wanted to rebuild the Tokugawa House, but she realized there wasn't much use after Rance took over and after what the racoon dogs had done, so she dedicates her life to what she loves: being on the front lines in battle and training. So much so that she wants to fight losing battles for the rush.
