From Chapter 175 to Viral Tiktok Sensation: the Rise of the Yuta Roach Kiss Trend
By Robert Thorne
Behind the absurd visual lies one of the strictest energy rules in the power system of Jujutsu Kaisen. Cursed spirits are composed entirely of negative cursed energy. When sorcerers manipulate standard cursed energy, they weaponize that same negative flow. However, Reverse Cursed Technique (RCT) converts negative energy into positive energy through multiplication. While humans use positive energy to regenerate lost limbs and heal organs, positive energy operates as pure poison to cursed spirits, destabilizing their bodies at a cellular level.
Few sorcerers can use RCT for personal healing, and almost none can export positive energy outward as an offensive weapon. Yuta Okkotsu is among that microscopic minority. By channeling raw positive energy into his mouth and exhaling it directly into Kurourushi’s head, he caused the curse’s physical form to disintegrate from the inside out. Physical contact eliminated any travel time, leaving the insect with zero window to retaliate or severed limbs to regrow.
The technique was lethal, silent, and invisible to the distant eyes of Uro and Ishigori. Yet the practical reality of the combat choice did nothing to soften the image. Akutami chose an anatomical delivery system that forced a beloved shonen protagonist to press his lips against a rotting, chitinous mouthpart. For the fandom, the mechanics were secondary; the meme was immediate.
