From level 80 onwards, the fastest way to level 100 in world tour mode is through Ryu.
1. you can spar with him with no down time.
2. beating his challenges in battle info will give you about 6000+ to 11000+ exp (no boost)
started the game on 2 July, and reach lvl100 + all Mastery in 10 days without speed running,
the grind isnt that time consuming, just boring.
