Natsu Dragneel and his friends travel to the island Kingdom of Stella, where they will reveal dark secrets, fight the new enemies and once again save the world from destruction.

The Earth is threatened by a powerful creature who destroyed 70% of the Moon with its power, rendering into the shape of a crescent moon forever. The creature claims that within a year, Earth will also be destroyed by him, but he offers mankind a chance to avert this fate. In class 3-E at Kunugigaoka Junior High School, he starts working as a homeroom teacher where he teaches his students not only regular subjects, but the ways of assassination. The Japanese government promises a reward of ¥10 billion (i.e. 100 million USD) to whoever among the students succeeds to kill their teacher, whom they have named "Korosensei" . However, this has proven to be an almost impossible task, as he has several inhuman abilities at his disposal, including the capacity of moving at Mach 20.

Every person has his or her own little world. Among the 34 bustling students of classroom 2-1, there are many such worlds.

Wonder about the world of Makina Juri, smiling and surrounded by gorgeous friends on the other side of the classroom. One day, I enter her world. But it's not as simple as it sounds.
