Nanatsu's protagonist, Melodias, is the sin of Wrath. At first, with his childlike appearance and actions, it seems oddly placed. The man runs a traveling bar that is carried on a gigantic pig, and he's generally very carefree despite being powerful. But occasionally Melodias displays characteristics nothing but deserving of his attribute of wrath, and that has been a key factor a few times. He travels with the naive princess Elizabeth and a talking pig named Hawk. Later on, more of the Seven Deadly Sins will join him.
Nanatsu no Taizai has battles that utilize both physical and magical weapons, the majority of these being against the Holy Knights. Each character has its own story and place in the series, and the cast manages to grow without getting too hectic.
Overall, Nanatsu no Taizai, while still ongoing, avoids being a fantasy solely relying on fanservice for appeal, but rather is a simple action story meant to be fun to read.
