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!
I finally realized you're 
the one who's our enemy.
Mir wurde endlich klar,
dass Sie unser Feind sind.
Por fin me percaté de que 
eres nuestro enemigo.
Por fin me he dado cuenta
 de que eres nuestro enemigo.
J’ai enfin compris…
Ho finalmente capito che
 sei tu il nostro vero nemico.
Eu finalmente percebi que você
 é o nosso verdadeiro inimigo.
Я наконец-то понял, что наш враг — ты!
