The day of the sports festival is finally here. Though Basara remains cautious of the mysterious enemy who manipulates people with magic, he happily enjoys the sports festival with Mio and Yuki as the three of them compete in the four-legged-race and enjoy their youth getting entangled and sweaty with each other. Meanwhile, Kurumi, who was placed in charge of guarding the school, discovers a suspicious individual. At almost the same time, a giant twister forms on the sports field. Basara fights to protect the students... but an unexpected individual appears!
The losers driven out of heaven turned 
into demons and built the demon world.
Die Versager, die aus dem Himmel
vertrieben wurden,
Los perdedores que fueron expulsados del Cielo
 son quienes construyeron el mundo demoníaco.
Los perdedores que fueron expulsados del cielo 
son quienes construyeron el mundo demoníaco.
Les perdants expulsés 
du monde des dieux
Coloro che sono stati cacciati dal paradiso
Os derrotados que foram expulsos do céu
Проигравшие были изгнаны из мира богов 
и создали мир демонов.
