|Hand seals||Ox → Snake → Hare → Ox → Tiger → Ram|
This technique is a powerful fūinjutsu that was invented by Miyuki Murakami. She used it to remove the Cursed Seal of Life from her brother during the Datenshi War arc, implying that it is very powerful. A prerequisite for the technique seems to be the use of the Evil Sealing Method, as Miyuki used the Evil Sealing Method on Daisuke before permanently sealing away his cursed seal with her fūinjutsu.
