Ch. 146Aizen's true purpose
After Setsugetsu died smiling, Aizen and Jörmungandr left Kirigakure with her body, and Aizen explained why he had tried to help her. He revealed that Setsugetsu’s body held a developing fusion of Ice Release and the Hydrification Technique, but she had died before it could give her a new life.
- Aizen and Jörmungandr mourned Setsugetsu, then left with her body for the Land of Fire.
- The Hozuki Clan searched briefly for Setsugetsu, found no trace of her, and gave up.
- Aizen told Jörmungandr that Setsugetsu’s frailty came from Ice Release resisting the Hydrification Technique as it transformed into a Kekkei Genkai.
- Aizen explained that the two powers had begun to show signs of fusion, and he had used a life-consuming method to strengthen Setsugetsu and give her a chance to survive.
- Aizen said Setsugetsu’s survival could have helped them understand chakra fusion, but she had died before completing the fusion.
