Crunchyroll previously streamed the past three seasons in several countries and territories worldwide, and will do so again for season four. It describes the anime’s main premise as:
Suzuki Iruma, human, 14, one day finds himself taken against his will into the world of demons. To add to his predicament, his doting owner and self-appointed “Grandpa” is the chair-demon at his new school. In order to survive, Iruma must deal with a haughty student who challenges him to a duel, a girl with adjustment issues, and so many more scary beings! Can this ultimate pacifist dodge the slings and arrows that are flung his way? As he struggles frantically, Iruma’s innate kindness begins to win over enemies.
