The third season of Mairimashita! Iruma-kun . This time it's the jungle! Human boy Suzuki Iruma becomes "grandson" to the great demon Sullivan and begins attending demon school where "Grandpa" serves as chairman. Winning friends -- and rising in demon rank, too -- Iruma thrives in his new environment, overcoming the harrowing ordeals thrown his way! In the new season, further challenges await... it's harvest season, and time for the annual test where students wade into the expansive and extremely dangerous (!) jungle to compete for food!! Classmates become rivals, and what erupts is a gargantuan battle of brawn and wits?

In this brand-new spinoff of the runaway hit series, Iruma is a dirt-poor but kind young boy who grows up in a ruthless city slum. One day, Iruma gives a severely injured old man his last loaf of bread and nurses the stranger back to health—only to find out that the elder gent is none other than Don Sullivan, leader of the Babel Mafia! Soon after, Don Sullivan comes back, whisks Iruma away, and begs the boy to become his grandson. And just like that, the curtains rise on Iruma’s chaotic new life as the next in line to a gigantic gang of—dare we say demonic mafiosos!
