Ender Theory

This list of enders will work any time, anywhere, no matter how prorated your combo is.

Combo	Damage	Cost	Meter Gain	Location
214B > j.214C		100 EXS		Anywhere
j.214C will always work in routes ending in 214B it's a great way to tack on a bit more damage and give yourself a better knockdown.
214B > CS , j.214C		100 EXS + Vorpal		Anywhere
Like the above ender, but you refund yourself a bit of the EXS that 214C costs you.
214B > j.214C > CS , Air Throw		100 EXS + Vorpal		Anywhere
The ultimate in j.214C enders. You get j.214C's amazing minimum damage, your EXS back, and the amazing oki off of Air Throw.
6C > AB > IW		200 EXS		Anywhere
Go to ender for cashing out IW when you don't have vorpal.
214B > j.236C , 22A > CVO , 236C > IW/IWEXS		200 EXS + Vorpal		Corner
Requires you to be around 30% health. Max damage ender for corner combos where you have the cycle. If you think you're going to kill them, spend the cash.

214B Start

214B is fast to be as threatening as it is. It's dangerous enough in the corner, but with practice, 214B can be a terrifying tool at multiple positions on screen.

Combo	Damage	Cost	Meter Gain	Location
Hard: 214B , md.2B > 214A , 5B > 6C > 236A , 66 > 5C > 9jc > j.6[C] > md.2C > dl.5C > 6C > AB/214B	3607/3616 (3963/3972)	0	87.xx Opp: 40.xx	Midscreen
Midscreen 214B pickup. Extremely difficult. Microdash 2B is a three frame window. This is an extremely rewarding combo to have in your arsenal, but it isn't necessary to be good at Akatsuki. No delay is needed when chaining from 5B to 6C after 214A.
Hard: 214B , md.2B > 214A , 5B > 6C > 236A , 66 > 5C > 9jc > j.b > j.6C > md.2C > dl.5C > 6C > AB/214B	3605/3614 (3959/3968)	0	89.xx Opp: 42.xx	Midscreen
Midscreen 214B pickup. Extremely difficult. Microdash 2B is a three frame window. This route has a slightly easier ender than the above route.
Easy: 214B , c.5B > dlc.5C > 236A , 214A > c.5B > 8jc > j.2C , 2C > dl.5C > 6C > AB/214B	3695/3709 (4059/4074)	0	74.xx/85.xx Opp: 40.xx	Corner
Routing corner combos for 214B start is much easier.
Medium: 214B , c.5B > dlc.5C > 236A , 214A > c.5B > dl.c5C > 9jc > j.BCA , c.5B > 6C > AB	3632 (3989)	0	75.xx Opp: 40.xx	Corner
Slightly harder corner 214B routing. This is worth noting because corner routes ending in j.BCA are extremely versatile. You can land and do immediate air throw for better oki, c.5B > 214B for CVO routing, or just keep it simple with c.5B > 6C > AB > IW when you want to spend meter but don't have the cycle on your side.

Click here for 6C Start Routes

6C Start

6C is your go to button for putting the hurt on. When you know you've got a punish opportunity, this is the button you want to land. Great for punishing reversals or calling out predictable jump angles.

Combo	Damage	Cost	Meter Gain	Location
Hard: 6C , 66 > 5C > 6B , 66B > 214A , c.5B > dl.2B > 6C > 236A , 66 > 5C > 9jc > j.B > j.6C , md.2C > dl.5C > 6C > AB/214B	3952 (4341)	0	102.xx Opp: 53.xx	Midscreen
Midscreen 6C punish routing. Fairly difficult.
Easy: 6C , 66 > 5C > 6B , 66B , 2B > 6C > 236A , 66 > 5C > 9jc > j.B > j.6C , md.2C > dl.5C > 6C > AB/214B	3792 (4165)	0	94.xx Opp: 46.xx	Midscreen
Much easier Midscreen 6C punish routing that still does solid damage. Being consistent with everything up to 66B is a great foundation for more difficult routing later! Don't sweat the small stuff.
Medium: 6C , 66 > c.5C > 6B , 66B , c.5B > 236A , 214A , c.5B > 236A , 214B , c.5B > dl.2C > dl.2B > 5C > 9jc > j.BCA > Ender	4180 (4590)	0	117.xx Opp: 63.xx	Corner
Corner routing for 6C punishes. Myriad of enders available after j.BCA.
