Kisame Hoshigaki is a character from the popular anime and manga series Naruto. He is a member of the criminal organization Akatsuki and is known for his shark-like appearance and powerful water-based jutsu. Kisame’s death is a significant event in the series, and is a key part of the storyline.

Kisame is killed during the Fourth Great Ninja War, a major conflict that involves many of the most powerful ninja from various nations and factions. During the war, Kisame is sent on a mission to infiltrate the Hidden Alliance of the Shinobi Forces, a coalition of ninja from the various nations who have banded together to fight against the Akatsuki and their allies.
Kisame’s mission is to gather intelligence on the Alliance’s plans and report back to his superiors in Akatsuki. However, he is eventually discovered by the Alliance’s ninja, who engage him in battle. Kisame proves to be a formidable opponent, using his powerful water-based jutsu and the unique abilities of his sword, Samehada, to overwhelm his opponents.
However, Kisame’s luck eventually runs out when he is confronted by two of the Alliance’s most powerful ninja: Guy and Kakashi. The two ninja, who have a long-standing rivalry, work together to take down Kisame. Guy uses his powerful taijutsu to wear down Kisame’s defenses, while Kakashi uses his Sharingan to copy Kisame’s jutsu and turn them against him.
In the end, Kisame is defeated by Guy and Kakashi, who are able to overcome his powerful jutsu and unique abilities. As Kisame lies dying, he is approached by his former partner and fellow Akatsuki member, Itachi Uchiha. Itachi offers Kisame the chance to take his own life, rather than be captured and interrogated by the Alliance. Kisame accepts Itachi’s offer and uses his own sword, Samehada, to commit suicide.
In conclusion, Kisame is killed during the Fourth Great Ninja War by the Alliance’s ninja, who are able to overcome his powerful jutsu and unique abilities. He ultimately takes his own life at the behest of his former partner, Itachi Uchiha.
