The Attack on Titan manga corresponding to season 4 continues the intense and captivating tale. It features intense battles, character growth, and plot twists that fans have been eagerly awaiting.
I wouldn't recommend downloading it from unauthorized sources as it's illegal and unethical. You can try purchasing or subscribing to legal platforms that offer it.
Attack on Titan Season 2 stuck quite closely to the manga. There were maybe one or two additions or changes to make it work better on screen, but it didn't deviate significantly from the original source.
In some aspects, there are differences. For example, the anime might emphasize certain plot points differently or have minor character developments that vary from the manga. But overall, it still captures the core story.
