In episode 21, "Forbidden Secret Technique: Reaper Death Seal!", the tension between the Hidden Leaf Village and Orochimaru's forces reaches a boiling point. The Third Hokage, Hiruzen Sarutobi, who is Naruto's mentor, is locked in a fierce battle with Orochimaru, who seeks to destroy the village.

The episode begins with Hiruzen using his knowledge of seals to try and stop Orochimaru from using a dangerous jutsu -- a technique that can seal away an opponent's soul at the cost of the user's own life.

As the episode progresses, we learn more about the technique that Orochimaru plans to use. The Reaper Death Seal is a forbidden jutsu that only a select few ninja have ever studied. It requires a great deal of skill and knowledge to use properly, and the risk of death is incredibly high. Orochimaru is willing to take that risk, as he sees the Third Hokage as his greatest threat.

Hiruzen, knowing full well the danger of the Reaper Death Seal, attempts to stop Orochimaru by using a powerful seal to trap him. However, the trap fails and Orochimaru is able to complete the final hand sign to activate the technique.

With the Reaper Death Seal unleashed, the fate of the battle -- and the village itself -- hangs in the balance. Naruto and his friends must work together to stop Orochimaru and prevent him from fulfilling his twisted plans. But even if they succeed, the price may be too high.
