There's an incredibly informative thread/FAQ about him in 2k2 written by Iie-Kyo located
here and most of the stuff is relevant so I won't re-post it.
Things to note:
-You can cancel the first hit of

+D.
-s.C, f+B, any DM or s.C,

+D [1hit] any DM -- are your friends
-
EDIT:hence, d.B, (d.B), d.A,

+D[1hit], Orochinagi DM (qcb~hcf+P) works well too.
-d.B., d.A, Mu Shiki (qcfx2+AC SDM) - check
-d.B is real strange where you can interrupt the move with a special, but it'll never combo. You can try d.B into

+P and you'll know what I mean. What does it mean? If do the old d.B, d.A, Mu Shiki shortcut (d.B,

+A/qcf~d.A,

+P) you might get an overlap.
-New qcfx2+K is so badass that you never get sick looking at it. 4-parter attack starting with the Aragami sprite,

+C [1hit] sprite, some unknown sprite (prolly syo's), and syo's final punch (ala syo striker in kof2k). Takes off slightly
less than orochinagi DM but it makes up for it with style points.
-qcf+K.K links to

+K even in the middle of the screen.
-SDM is Orochinagi
-HSDM is Mu Shiki
