In Season 4 of the anime series “Attack on Titan,” Eren Yeager’s age is 19 years old. However, it’s important to note that the timeline of the series can be a bit confusing, as it involves time jumps and flashbacks.
At the beginning of the series, which takes place in a fictional world where humanity lives inside a walled city to protect themselves from giant humanoid creatures known as Titans, Eren is a young boy who witnesses the destruction of his hometown and the death of his mother. It’s not entirely clear how old Eren is at the beginning of the series, but he’s likely around 9-10 years old.
As the series progresses, there are several time jumps that take place. In Season 2, there is a time skip of around three years, during which Eren and the other characters have undergone intensive military training to become soldiers capable of fighting against the Titans. By the time Season 3 begins, Eren is around 15 years old.
In Season 4, there is another time jump of four years, which brings Eren’s age up to 19 years old. At this point in the series, Eren has become a skilled fighter and leader in the military, and he plays a key role in the ongoing conflict between the Eldian people and the Marleyan government.
Without spoiling any major plot points, season 4 of Attack on Titan follows Eren and his comrades as they continue to fight against their enemies and uncover the truth about the Titans and the world beyond the walls.
It’s worth noting that the age of the characters in “Attack on Titan” can be somewhat ambiguous, as the series doesn’t always provide clear indications of how much time has passed between events. Additionally, the series also includes several flashbacks that show the characters at different ages, which can further complicate the timeline. However, based on the information provided in the series, Eren’s age in Season 4 is 19 years old.
