What is Naruto's Namikaze Minato's most powerful move?

Forbidden Technique·Sealing the Ghouls: The super S-level ultimate sealing technique of Konoha Village. Using this technique is an ultimate ninjutsu that summons the God of Death and causes the God of Death to devour the enemy, but it is worth mentioning. What's more, when the person who performs this technique completes the seal, he also makes an agreement with the God of Death - selling his soul to the God of Death. In other words, while devouring the enemy and completing this technique, his soul will also be sold to the God of Death. Devour, and the souls of yourself and your enemy will "hate and fight each other forever" in the belly of death.

Contract seal: Can remove the caster's psychic spell.
