Liones High School is a prestigious institute for the elite And also very strict , with all but seven of the students in attendance

They are a group known for breaking the rules and called the Seven Deadly Sins and The princpal's daughter, Elizabeth. Meliodas is the leader of this group and is also a troublemaker. Big one

The Student Council goes to a lot of trouble to keep them safe, but it always ends up being the opposite

It's a normal day with a new student joining the school, specifically the problem class

“A new student will join the class. Please be nice to him and don’t get him into trouble.”

The teacher said while clearly staring at the back of the classroom where some members of the Seven Deadly Sins were

Meliodas had his hands in his pockets and leaned back in his chair with an indifferent expression

"Yes yes we will~"

He said with a small smile as Elizabeth Who was in the seat opposite him looked towards him with a slight frown

"Meliodas-sama, don't be rude."

Ban, who was sitting in the back yawned bored from the class mutter

"I hope he's a fun person."

Meliodas nodded,While Diane was curious And King sitting a little further away was already asleep at his desk As for Gowther, he was reading a book silently

And just at that moment the classroom was stormed by the new student.

It certainly wasn't a good sign that the new student was a sane person.
