You absolutely have to check out **Chainsaw Man** if you haven't already - it's got exactly the same energy as Jujutsu Kaisen with sick action scenes, a well-thought-out story, and characters that actually develop. The German dub is also really well done. The second season is either airing right now or just finished, depending on when you're watching this.
Besides that, I'd recommend **Demon Slayer** if it's not already on your list. Sure, it's pretty old by now, but if you're into good character development, it's perfect - the story builds up really nicely and the fights look insane. It's available in German too. And then there's **My Hero Academia**, if you're into the superhero school vibe - you really get to see the characters grow throughout the seasons.
If you want to try something newer: **Solo Leveling** just got adapted and it's really solid if the power-level system and the constant development of the main character are your thing. German dub available as well. It's more from the manhwa side of things, but feeling-wise it still fits with what you like about Jujutsu Kaisen.
