Unfortunately, yes. Eren dies at the very end of the series. For fans, this could be a hard truth to deal with since we’ve been following his journey to avenge his parents’ death and discover the world outside the walls from the very beginning.
And it’s also not common for mangakas or people who make manga to kill off their main characters. What’s even worse is how he died. But the series ends in such a way that his death feels important in tying everything together.
At the end of the manga, Mikasa, Armin, and Levi, as well as other fellow soldiers, are facing off against Eren and the source of all matter in battle. After some time, Mikasa is able to enter into the mouth of Eren’s Titan form where his actual body is visible and she decapitates him.
Eren has escaped death before and it’s possible for members of the Titan race to rapidly heal themselves and even regrow entire limbs, but it doesn’t work this time.
