Taking a break from his time as a teacher, the powerful slime Rimuru Tempest returns to his kingdom, eponymously named Tempest, just in time to begin negotiations with a nearby nation—the Kingdom of Eurazania. While the negotiations are anything but peaceful, they do end successfully, allowing Rimuru to return and finish teaching. When trying to again return to Tempest, this time permanently, Rimuru is stopped by a mysterious figure who is somehow able to constrain the many magical abilities he has at his disposal.

They are not just trying to bring harm either—they have the intent to kill. Can Rimuru overcome his powerful and dangerous foe and return to Tempest before it is too late?

After a stern yet compelling speech by Otto Suwen, Subaru Natsuki solemnly swears that he will successfully make it through this timeline and save everyone he can along the way.

To the average person, psychic abilities might seem a blessing; for Kusuo Saiki, however, this could not be further from the truth. Gifted with a wide assortment of supernatural abilities ranging from telepathy to x-ray vision, he finds this so-called blessing to be nothing but a curse. As all the inconveniences his powers cause constantly pile up, all Kusuo aims for is an ordinary, hassle-free life—a life where ignorance is bliss. Unfortunately, the life of a psychic is far from quiet. Though Kusuo tries to stay out of the spotlight by keeping his powers a secret from his classmates, he ends up inadvertently attracting the attention of many odd characters, such as the empty-headed Riki Nendou and the delusional Shun Kaidou. Forced to deal with the craziness of the people around him, Kusuo comes to learn that the ordinary life he has been striving for is a lot more difficult to achieve than expected.

UA Academy's Class 1-A has been the focus of a substantial amount of public attention due to the multiple villain attacks they have faced over the past school year. This attention has left Class 1-A's rivals, Class 1-B, feeling quite bitter. Desiring to prove their skills, they look forward to the opportunity that has been given to them: a set of mock battles between the students of each class. The classes are split into squads of four, each of which is tasked with capturing the other group members. The winner is the group who first secures all of the opposing team. While this sounds simple, a curveball is thrown into the mix with the inclusion of General Course Student Hitoshi Shinsou, who wishes to transfer into the Hero Course. Despite using his training with Class 1-A's homeroom teacher Shouta Eraserhead Aizawa to prove that he's capable of being a real hero, he is still far behind the others due to his lack of experience. However, Shinsou is determined to overcome this challenge. Thus begins the fiery competition between Class 1-A and 1-B as each tries to prove that they are superior to the other.
