Man, King, Diane and Helbram backstory is sad. Now, I see the real reason behind summoning the demons
Also, like the little touch that both King and Diane lost track of time because they so old
After reading the first 9 chapters, I find the manga series enjoyable but not as awesome or outstanding as Toriko, Magi, and Fairy Tail. I have been reading Shonen series. Toriko and One Piece were my newest Shonen shows to watch last year.
If I had to scale the Shonen series I'm currently reading, it will be like this:
One Piece > Magi > Fairy Tail > Toriko > Seven Deadly Sins.
Seven Deadly Sins hasn't wow or reeled me in from the beginning like Toriko and Magi did.
