Cannot be done in the corner, and does not work on Haohmaru, Nakoruru, Rimururu, Shizumaru, Kazuki and Sogetsu. If the opponent ends up in the corner, switch to using a 2C starter combo.
Back throw > 66A > 14-hit CD
Difficult combo, but it works against everyone so it's worth practicing.
Back throw > j.C > 66A > Various
CD, 66C, 3D, Rage SCS, Issen
Does not work against Haohmaru, Nakoruru, Rimururu, Shizumaru, Kazuki and Sogetsu. Also cannot be done if the opponent is deep in the corner.
Backhit 2C xx 5AB > 2C > 3S OTG
Slash
14-hit CD (12) xx WFT
CD BBC xx 421A
(Corner) Backhit 2C xx 22S > 66A > CD BBC xx WFT
For whatever reason, this only works if Gaira is on the right side of the screen. If he's on the left side, 22S will knock down on hit. The link from 66A is also a little difficult.
