Have you tried using spikes? They are nice. You're gonna to pretty much have to fight your way in. Drop a spike, move forward, see what the opponent is doing, do the smart thing to counter what they are doing, rinse and repeat until you are in.
Labrys doesn't really have a go to ground move for neutral like Mitsuru or Yu so we have to make the best use of our A moves, 2B and sweep to get the knockdown.
And 236A/B > 6 > A seems to be plus on block, but only stops characters like Labrys and Yukiko from mashing. Characters like Chie and Akihiko can jab out before we can do anything after it. But its an option to get in quickly I guess.
