Hollow Technique: Purple.
A technique that few even within the Gojo clan knew about. By overlapping the forward technique, Blue, with the reversed technique, Hollow Purple, it generated imaginary mass that could be launched outward. It manifested as an energy wave capable of cutting through space, leaving smooth-edged circular gouges in whatever it struck. It was one of the most destructive skills in the entire series, with immense range and diameter, leaving nothing intact in its wake.
The activation gesture was a finger flick... Was this some kind of Divine Finger Flick? Chanting the incantation could further enhance the technique's effect!
Now, a nearly full-power Hollow Technique: Purple struck the Futsu-no-Mitama Sword. A second later, its energy exploded, blasting Uzumaki Gamu's Shadow Clone into fragments before leaving a crater two meters deep and a sizable mushroom cloud!
Only the Futsu-no-Mitama Sword fell to the ground in the end-of course, it was completely unharmed. The electricity constantly flickering over it was the only evidence that the attack had actually happened!
After setting Yuji Itadori down outside, Uzumaki Gamu walked over to Satoru Gojo and said, "Looks like it couldn't absorb it!"
"No, it absorbed most of the energy... Normally, that attack would've erased everything within several hundred meters!" Satoru Gojo explained.
"...Is it really okay to use something that dangerous at school?" Uzumaki Gamu quipped.
"Weren't you handling the defense? Then it's fine... Hm?" Satoru Gojo suddenly noticed something was wrong!
Uzumaki Gamu noticed it too-the electricity spilling from the Futsu-no-Mitama Sword was growing more intense, as though it were about to... release something.
A second later, the true ultimate technique erupted on the school's athletic field-the Futsu-no-Mitama Sword exploded!
Uzumaki Gamu and Satoru Gojo had barely reacted before the explosion swallowed them! Then the shock wave spread outward...
Well, the
