Yes, after 6C+staff return knockdown you can go into Daisharin in the 3 direction to pick them up. In the corner I have seen B&B...>6C>Daisharin(333333)>IAD (you should be airborne after Daisharin) j.B>j.C>land>Chun (maybe tk?)>Chun>staff falls>6C>3C. Going off of memory, feel free to correct me.
This nets her around 6k damage + knockdown with staff set in 2D position for oki. I wish I had the video but I don't feel like wading through links atm. I was informed Daisharin combos work midscreen as well with a different combo for Litchi, mostly involving j.C's and Chuns to dribble the opponent back down to the staff super.
At any rate, I -sometimes- don't understand why Litchi holds on to 100% meter but most of the time it's because her supers are only situationally useful.
Daisharin - Situationally useful for control, but most characters have metered options that will punish random Daisharin activation. Jin can wave super, Tao can 214214B, Bang can run super if you do it point blank, Nu can arrow super, Litchi can Ryuuiisou or activate her own Daisharin, Tager can situationally spinny super, doing it against Hakumen puts both characters at a high-risk/high-reward situation. Granted, there are many opportunities when Litchi can freely Daisharin but there are times she needs to respect the opponent and refrain from doing it.
Kokushi Musou - Setups for this (especially in CT) were 99% all gimmicks that could be tech-rolled out of. There are some pretty legitimate-looking setups in the corner now with Kokushi in CS with the ender: IttsuC>6C(2hits)>6Kote>back dash>wait. If they roll they'll be placed point back for you to pressure, if the quick-tech you can Kokushi. But even this can be jumped out of under certain situations. To be honest, the only Kokushi setup I see that gets full respect is air CH Tsubame 25% away from the corner>Kokushi. Furthermore, like Daisharin, some opponents have metered options against Kokushi setups so there are situations where it's better to simply not do it.
Ryuuiisou - Actually, this is a good super. The fear of having 50% is often scarier than the super itself.
Blah blah blah I talk too much.
