Dude it's D&D 3.5 framework being used with Naruto flavored stuff instead of the usual elves, wizards,and dragons stuff from D&D proper. 

Also yeah Wulin pretty much does the fighting stuff rather well and better. You got externals and weapon style stuff for like how you fight and internal for magic stuff and chi conditions which can be use for weird effects. 

However if want something more mechanically complex I can totally do anima with everyone being a tao or technician as their splat totally lets them do hand seals and summoning stuff as well as one of the artifact weapons being a puppet.
