Welcome.~
You might want to read up on the site's custom history a bit, the concept of Jinchuuriki as seen in the canon series won't exist here. As for clans, we're trying a bit of different approach, in that abilities that would normally be locked to certain clans can be taken by anyone willing to do the work to unlock them from scratch. You wouldn't be born able to use the skills, you have to discover them for yourself. If you're willing to put in the effort, enjoy that Shikotsumyaku.
