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?

The Misfit Class's New Term
The students of the Misfit Class have been given a special order. The order was for all of them to reach the Dalet rank before they become second-years, or they would lose the Royal One that they had worked so hard to obtain. The next event where they can raise their rank is the Harvest Festival. In order to help them raise their ranks in such a short amount of time, the school had prepared special tutors for them. The new term had only just begun, but unexpected trials await Iruma and his friends.

Master Bachiko
Iruma and Lead end up being trained by Robin's relative, Barbatos Bachiko. Bachiko is very skilled and was personally asked by Sullivan to assist Robin with tutoring the kids. They were supposed to have a rather hard training schedule... but all Bachiko asks them to do is random errands. Lead has had enough of that and goes back to Robin. Iruma is left frustrated and alone. He learns that Asmodeus and Clara have been training and decides to take matters into his own hands!
