Thank you for the suggestion, but I have no plans of adding character roles right now. There is a clan based off of Jiraiya called Gamanoabura in Hidden Leaf. There is a clan based off of Orochimaru in Hidden Sound called Shiroihebi. And yes, Senju Clan. which Tsunade is apart of in the anime/manga. We have more than 30 choices for characters to go for right now, many of which require major development and tuning for their clans, setups, and character jutsu. I need to prioritize improving the quality of what we have now, and I think that it would be out of prioritization to create more character positions.
