Ch. 121Sage Cursed Seal!
Asuma used a blood-drawn Sage Cursed Seal to transform Rin Nohara, embedding symbols infused with his Senjutsu Chakra into every cell of her body. Rin survived the painful ritual and gained a lasting sage state, though Asuma could not predict how the changes might develop.
- Asuma explained that his Sage Transformation seal would spread Cursed Seal power through Rin Nohara's entire body and asked Tsunade, Shizune, and Yūhi Kurenai to help prepare it.
- Tsunade, Shizune, and Yūhi Kurenai drew the symbols over Rin Nohara's body using blood from Asuma's Shadow Clones.
- Asuma activated the seal, and its symbols penetrated Rin Nohara's skin, muscles, organs, nerves, brain, and every other cell, causing her intense pain.
- After the ritual ended, Rin Nohara gained a violet forehead mark and Chakra that initially resembled Asuma's.
- Asuma explained that Rin could control the seal and use Sage Chakra, while its ongoing effects might eventually let her cells absorb Natural Energy on their own.
