I only focused on the 5B into shooting star route.
Here's what I found...
5B>6C>214A~C>236D>...
6A>2D>2C>214A~A>6A>JB>JBD>665CC>JB>JB>corona 4016
6A>2D>2C>214B>JBD>665CC>JCB>JCB corona 4043
6BC>5D>5CC>JBD>665CC>JCB>JCB corona 4107
To expand on your route since you get more damage from 2C>2D vs 5B>6A>2D
5B > 6C > 214A~C > 236D > IAD j.B (J.B if you're already in the corner)> j.D >662C>2D...
5B>6A>JB>JB>corona
6BC>JCB>JCB corona
6BC>5D>236A
2C>214A~A> 6A>JB>jc>JD doesn't work and 6A>JBD seems very tight too since you cant hit the JB too low otherwise JD will miss. However 6A>JB>JBD felt easier for some reason.
Next time I'll do 6C>corona enders to see if she gets more damage, and find some more okizeme combo enders.
