After a discussion with Hibiki about his plans after middle school, Asumu is reminded that he has no choice but to pass his entrance exam into Jounan, and he resolves to not see Hibiki until he gets in so he can share the good news. Meanwhile, Hibiki heads out after news that one of his comrades was injured in a fight, but can he handle an unfamiliar type of Makamou?

Ibuki, thinking Asumu is Hibiki�s apprentice, takes Asumu to where Hibiki and Kasumi are located. Hibiki and Asumu have a discussion about life and the challenges that everyone faces, leaving Asumu with a renewed passion to do well on his entrance exams. Hibiki then returns to battle the Bakegani that defeated him previously.

A new school year has started and Asumu enters high school but still has mixed feelings on the path of life he has taken. Through all the aimless wandering he finds himself back at Tachibana�s Sweet Shop, but Hibiki has traveled out to the countryside after a call about people strangely disappearing where he faces off with new armored versions of the Douji and Hime.

After going through a false wall in Tachibana�s Sweet Shop, Asumu stumbles upon the Oni R&D room where Midori shines some light on Hibiki�s past. Meanwhile, Hibiki believes he�s discovered the secret to defeating the Armored Douji and Hime and begins to time their transformation, but he has to hurry as a Nurikabe is making its way towards the village below the mountain!

A mysterious Oni Armor, that gives the wearer the power of an Oni, has been stolen from a shrine. The thief uses it to attack Oni and Makamou alike; leaving the Oni wander what is the thief�s motives for using the armor. Meanwhile, Akira struggles with her hatred for the Makamou and what it means for her Oni training�

Having taken Todoroki�s transformation brace, Shuki sets out to get her vengeance on the Notsugo, despite the danger it poses to her former Oni comrades. As a result, Ibuki is tasked with the heavy burden of eliminating a fellow Oni, while Zanki struggles with who his former master has become�

With Orochi approaching, the number of Makamou has risen sharply, straining the Oni and their ability to handle it. With Hibiki taking Asumu and Kyousuke as his apprentices, the Oni are down even more, but even amidst the training, Hibiki rushes into battle, while Todoroki is gravely injured as he and Ibuki are overwhelmed�

After being crushed by a giant Makamou, Todoroki is rushed to the hospital, but while he survives, his prognosis is grim as he may never become an Oni again, driving him deep into depression while Zanki struggles with the situation. At the same time, Hibiki continues to train the boys, but Kyousuke�s arrogance and lack of physical skill holds him back, until he erupts with frustration at Hibiki�

Leading the Oni to a stone with ancient Oni script on it, the Man and Woman make their next move towards preventing Orochi, but the cost of stopping it may be too much for Ibuki to bear. Meanwhile, Kyousuke becomes increasingly obsessed with becoming an Oni, with his focus on his training consuming him, while Asumu questions what it means to put your life on the line to protect others�

Coming to terms with what dying without regrets means to him, Asumu decides to walk away from his Oni training, leaving Hibiki seemingly disappointed, but with Orochi imminent, there�s no time to swell on it. Hibiki, Ibuki, and Todoroki set out to complete the ceremony, but Hibiki tricks the other Oni and escapes with his drumsticks, setting out for the purification site as the final battle begins�

Leading the Oni, Hibiki brings Orochi to a halt and purifies the earth as the ancient writings described. One year later, Asumu has moved on from Takeshi and the Oni and now interns at a hospital in his quest to find his own path to helping people. But when Mochida is captured by the Man and Woman as a new specimen for their experiments, Asumu�s path leads him back to Hibiki, Kyousuke, and the other Oni once again!
