Itachi Uchiha, a renowned character from the popular anime and manga series Naruto, never had a girlfriend. Therefore, there is no one who killed his girlfriend.
The question might stem from a misunderstanding or misinterpretation of the narrative. Itachi's primary focus was on his mission to protect his village, Konohagakure, and his younger brother, Sasuke. He was known for his complex and tragic backstory, which involved difficult choices and personal sacrifices.
Here are some possible reasons why this question might arise:
- Fans' interpretations: Some fans might have created fictional scenarios or theories about Itachi's life, which could include a romantic relationship and a tragic event.
- Misinformation: Misinformation or inaccurate information spread online or through fan communities could lead to the belief that Itachi had a girlfriend who was killed.
- Confusion with other characters: It's possible that the question is referring to another character from the Naruto universe who had a girlfriend who died.
It's important to rely on official sources like the Naruto manga and anime series for accurate information about the characters and their storylines.
