- OP main character with a "happy-go-lucky" attitude
- Set in medieval fantasy world
- The early arcs concentrate on building the "crew" around the main character
- General vibe and color scheme are similar.
- Both shows can take themselves seriously when they want to, but there's always room for a bit humor, too.
- distinct and interesting side characters
Both are isekai's with OP MC'S
Both have a "Demon Lord" Theme common in them
Both focus on building a team of powerful people (7 deadly sins and Rimuru's entourage)
In both the anime, all side characters are not at max power at first but become stronger and stronger till they reach their full strength.
The only difference is that in 7 deadly sins, there is no world building involved.
