Well if you decide to include them, I could be the 7 tails. o3o
You know I'm not even sure I know what the seven tails was.
They don't mention what most of them are honestly it's kind of annoying.
Erm damn I guess it's worth mentioning this but the ten is the maximum amount of Jutsu a character can posses. So Kaiser you need to sacrifice a technique to get any chance at getting the Rasengan. Also another thing I forgot the following is the list of the basic ninja pack it includes all of the items that all Ninja have. It's kind of a catch all but means people don't need to include kunai, shuriken and the like as extra weapons. Unless you want more then the basic amount.
Ninja pack (basic gear) You can have more but they go into your extra weapon column.
.Kunai 2x (one in leg holster)
.Exploding notes 4x
.Smoke bombs 3x
