Surangama

Śūraṅgama is a unique Uchujutsu transcription seal developed by Kana Korimachi and passed down to Chiyoko Otsutsuki. It's designed to restrict the Rinnegan's various techniques. Kana saw how potentially dangerous Madara Uchiha had become and could be and decided that should another arise, they could be dealt with in a swift and effective manner.
