It just feels like and adventure. It's great fun. It ain't afraid to get serious but it's always lighthearted and fun. Then again I'm only 50 episodes In.... it could change drastically more than once.
The animu is like 800 episodes and the mango is nearing 900 with no sign of it stoping soon. Even Berserk, which is much shorter and with better art, required me to take a break from binge reading it.
