So far, the characters (that i know of) that can do normal combo's into their ougi's are,

Sage Naruto: (Finished ^O Combo, then Rasen Shuriken 1 second before you land (it will put you on the ground automatically)

Wind Shuriken Style Naruto: Complete ^O combo into Delayed 1-2 (seconds) Ougi
9Tails Rasengan Naruto: Same

Tenten: Delayed jutsu (they have to run into it after you've set them) into immediate Ougi

Kiba: (Complete Neutral O combo immediately into Ougi)

Hinata: 4 hits of vO combo, immediately into ougi

Chiyo: (Finished ^O combo [UP CLOSE] into ougi)

Jiraiya: (O combo, only 3 hits, wait 1 second, ougi.)

Hidan: Chakra dash into immediate ougi

Shikamaru: Chakra Dash into immediate ougi

if you find any others, post them! ;3 sadly, tsunade's heaven kick -> ougi has been proven faulty ;( as well as sasori's ^Oougi and Kakuzu's tilting ougi

Ah.. look at these gimmicks.. Glad to see that Tenten's is nearly fool-proof. I used it once and thought it was pure luck.

Hope its ok to post here im new, but asuma has one similar to hidans and shikamarus but there can be little to no wait time after the chakra dash.

of course its okay for you to post here, so you're saying asuma can dash into his ougi?
