Aruto and Izu visit the artist behind the former's favorite manga series, Chōichirō Ishizumi, to deliver an illustrator HumaGear, only to learn he is done with drawing mangas. While Aruto tries to find a way to help reignite the fire in his heart help Is understand the true meaning of passion, he identifies a way to defeat the new Magia and creates the Flaming Tiger Progrise Key.

Both Aruto and A.I.M.S. are called to a high school whose HumaGear basketball coach is nearing technological singularity while developing the mannerisms of a hot-blooded coach, which the school's faculty fear could become problematic if not he is not immediately rebooted. Meanwhile, Horobi gives a new HumaGear the ability to learn to enable it to become the ultimate assassin, whilst saving its data into the Dodo Zetsumerise Key. Before he can strike however, he is stolen by Yua, who then releases him to observe his actions. When the basketball coach HumaGear begins displaying sentience, Jin reveals that all the previous Magias that he created also attained sentience, which infuriates Aruto further. Yua gives Aruto the Freezing Bear Progrise Key to defeat the two Magias. While Jin recovers the Dodo Key, Yua makes off with the Mammoth Key.
