Sealing techniques grant the user the ability to seal away things such as weapons, tailed beasts and other shinobi. It is also one of the only things that work against Edo Tensei. So, today I have ranked the shinobi who are best at using fūinjutsu.
Jiraiya was well versed in sealing techniques. He knew about Naruto’s Eight Trigram Seal and knew how to undo it. Jiraiya was also able to seal away the flames from Itachi’s Amaterasu. Also, Jiraiya created a seal of his own that could suppress Naruto’s Nine Tails chakra.
Gaara was the jinchūriki of Shukaku. He is able to seal opponents due to his sand. Earlier when he possessed Shukaku, he could amplify the power of sealing techniques. Gaara sealed many reanimated shinobi during the war. He usually encloses them in giant pyramid which restricts their movement and also permanently seals them. Gaara also possesses the magnet release which is very useful for sealing.
