Kearizu was an excluded member of her clan, a "failure", but Gojo Satoru felt it since they met when they were 12, she was different, so much more than a healer and he was right. After a tragic event, she finally became the gifted child and the only user of the full Chaos curse technique. The same technique that was created almost 300 years ago by her ancestor Ririzu. After the incident, felt as if that energy was always hers and there, present, waiting for the right moment to manifest. I do not own any of the characters, just the Rin clan characters. Everyone else is created by Gege Akutami and also credits to MAPPA for the great animation. The pictures I obtained are from pinterest. That is when he knew he was right, Kearizu became the chaos within his infinity, the energy that allowed him keep balance and viceversa, because without chaos (transmutation) there is no universe and without a universe there is no infinity. This story will tell you a bit of their dynamic, how they fell for each other and felt as natural as breathing.
