Sealing Technique: Lion Closing Roar

This sealing technique completely blocks the target's chakra with a sealing formula (封印式, fūin-shiki) drawn on the ground or a wall. This is done by closing all thetenketsu of the person caught in the middle. When the target is sealed, a stylised kanji for "close" or "shut" (閉,hei) appears in the middle of the sealing formula.

To successfully seal the target, one has to get them exactly inside the sealing formula. This requires great accuracy and is very difficult. Various methods can be used to make this easier. For instance, one can prepare a puppet or a ninja tool like the Lion-Headed Kannonwith this sealing formula.

Lion-Headed Kannon
The Lion-Headed Kannon is used by Shadow as a means for using the Sealing Technique: Lion Closing Roar. It starts out as a small ball that can be held in one's hand, but when thrown grows out into a man-sized lion's head with thirty-two large fangs and a mouth which is wide open. If aimed correctly, the tool will pin the target against a wall with its mouth, making them unable to move.
