Hollow Technique: Purple

is the colliding Limitless, an exceptionally powerful secret extension technique only known to a few in the Gojo Clan.
==Description==
This technique brings the concepts of motion and reversal into reality. Hollow Technique: Purple is created when applying the repulsive forces of Red with the attractive forces of Blue. These violent forces annihilate anything it comes into contact with, ripping apart matter at the molecular scale.
A blast of Purple can destroy a city, carve through a forest, or disintegrate critical sections of an individual's body depending on its deployment. If its power is left completely unchecked, it can even damage the caster. Even so, sorcerers can negate these effects; the magnitude of cursed energy funneled into bodily reinforcement helps protect against Purple. 
Purple is activated with a hand sign that extends the index and pinky fingers outward while leaving the rest folded. Purple is unleashed when the sign switches to a pinching motion using the pointer and thumb while also extending the middle finger. 
==Usage ==
Until his second confrontation with Toji Fushiguro, Satoru Gojo was always unable to use Red and therefore never had access to use Purple. Only after the true power of the Limitless was awakened within Satoru could he utilize Red and potentially Purple. Toji was from the Zenin Clan and had information on countering Red and Blue. Purple is a secret even within the Gojo Family that few know about. Toji was oblivious to the fact that Satoru could unleash such a devastating attack and suffered a direct hit, erasing the left side of his body. 
Satoru used Purple on a much greater scale to end the enemy invasion on the Kyoto Sister-School Goodwill Event. After dealing with Juzo Kumiya, Satoru noticed Hanami was a fair distance away from him and would likely get away. In an attempt to exorcise the special grade from a great distance, Satoru decided to go all out and unleashed Purple. This annihilated a great portion of the forest and was so nonstandard that Aoi Todo couldn't even tell if Hanami was exorcised.
Satoru's opening move in his showdown with Sukuna was a surprise attack using Purple. In tandem with Utahime Iori's Solo Forbidden Area, Satoru used the hand signs and incantations he would ordinarily omit. This increased the cursed energy output of Purple to 200% and Satoru launched it from Shibuya to Shinjuku where Sukuna laid in wait. Kiyotaka Ijichi used a barrier to conceal Satoru, causing Sukuna to read the attack late. The surprise attack eviscerated around a four kilometers stretch of buildings between the cities and destroyed Sukuna's cursed energy-reinforced arms as he attempted to defend himself at the last moment.
During the climax of the showdown, Satoru concluded his only way to defeat Sukuna and Mahoraga was with Purple. He improvised amid the fight, combining Blue and Red after the two orbs had been fired off separately. Satoru chanted the incantation for Purple's activation as the two infinities collided, resulting in an imaginary mass that carved through Shinjuku. Purple released as an omnidirectional explosion rather than a directional blast. It decimated destroying a massive part of Shinjuku, disintegrated Mahoraga and heavily damaged Sukuna.
