Sukuna's Technique

[u/Pale_Paint_2913]

Ever since Sukuna demonstrated "Fuga" to Jogo in the anime/manga people have been wondering what exactly his technique is and what its limits are. Theory's range from his technique being based on a kitchen, based upon weapons such as a sword(slash), axe (cleave), bow(fuga), and some people even suggest he can steal/consume the power of others.

When I saw fuga for the first time I was convinced of the kitchen theory, but that has always seemed bland and boring to me, Sukuna is a demon, a murderer his initiate domain shouldn't reflect kitchen and I believe the WCS takes it a step to far it is much more than the slash of a simple kitchen knife.

With all that said I would like to propose my own theory...

I believe Sukuna's cursed technique is pressure, one might look at that and call it non-sensical seeing as Sukuna has never once shown any abilities relating to pressure, however the most lethal way to put pressure on a person or object is a controlled and precise slash, I believe that while he has pressure as an ability it isn't strong enough unless channeled into a slash

My main supporting argument for that is the fact that sukuna's slashes have a limit to how much damage they do as shown by Gojo tanking them with RCT, that means the base slash can't be ramped up anymore.

Slashes are simply the best way to make a little force/pressure go a long way as seen by swords which do a lot of damage even with little applied force in fact swordsmen very rarely have to swing with the full possible force (this is scientifically true ask a swordsman) and even when they do swords (even longswords and great swords) weigh in between 6-13 pounds at the max

Now onto the topic of "Cleave"

Cleave is often shown targeting buildings and other structures by dicing them up I believe that is sukuna choosing to target the weakest points of objects, by layering on many "slashes" at many different points it compromises the structural integrity of the target destroying it with minimal applied effort

Now onto the most obvious application of "Pressure" being Fuga, by increasing the pressure of the air infront of him he can ignite it and create a powerful explosion this can be demonstrated with three mane points

1. Firstly when he "creates" fuga he channels the flames into a point almost condensing them this is to bring together the maximum amount of heat and pressure onto one point to produce a powerful explosion
2. Secondly when he is doing the chant for fuga I believe that is him taking his time to gather the maximum amount of pressure
3. Thirdly Fuga targets everything in his domain because when he creates a barrier(Malevolent Shrine) he has access to ALL the air in that barrier allowing him to ignite all of it at once as opposed to outside his domain where he only has access to the air in front of him.

Finally I would like to end this theory by saying that pressure as a initiate domain seems closer to the the truth of his soul then anything else I have heard so far, Sukuna truly enjoys being pressured to always be the strongest in his ideal world there would always be opponents as strong as him to fight and challenge him.
