Osamu Kirin has been quietly exterminating the demons that have been appearing in the present day. He asks Towa, Setsuna, and Moroha to slay demons at the concert that is happening.
And that's why the Grim Comet
came to the world of Reiwa.
.لهذا السبب ظهر المذنب الحالك في عالم ريوا
und dadurch verantwortlich dafür,
dass Yōreisei diese Welt heimsucht …
¿Y por eso el cometa Aciago
 vino a la era Reiwa?
¿Y por eso el cometa Aciago
ha aparecido en la era Reiwa?
C’est donc à cause de moi
que l’étoile spirituelle s’approche tant.
Quindi sono io la causa per cui la Stella 
dello Spirito Demoniaco è giunta nell'epoca Reiwa.
E é por isso que o Cometa Sombrio
veio ao mundo de Reiwa.
И что именно из-за меня Демонический дух
оказался в периоде Рэйва.
