How to unlock the You're Already Dead achievement in BlazBlue: Continuum Shift - Definitive Guide
Make sure you have two controllers, pick Hakumen on the first and Carl on the second because he has the least health.
Have Carl use up his barrier until he enters the danger state then continually walk backwards until he enters negative penalty (He should have a red glow around him). Then simply do Hakumen's 632146C distortion drive. Make sure you are close enough so that the sword hits him as I'm not sure the shockwave alone will do enough damage and make sure you hold down C to charge it up and you should kill him in one hit, netting you the achievement.
Might be worth setting the time to infinite as well just in case.
There is actually a really easy way of doing this opposed to the long combo shown under "Twirling toward Freedom".
Press when you pick Hakumen to put him in beginner mode and pit him against Iron Tager. Get Tager into Negative and Danger status. To get him into Negative Status have him back away from Hakumen while Hakumen is slowly moving toward him - if it doesnt happen by the time Tagers at the Corner, have him jump over Hakumen and proceed to the other end. To get him into the danger status simply hold while guarding until his barrier gauge is empty and the word "danger" is shown within Tagers health bar.
Once the two statuses have been met, place Hakumen right next to Tager and hold to use a fully charged Shippu distortion. If done correctly it should deal over 10,000 for your trophy.
