The new national stadium is chosen as the location for their final showdown. After describing his theory on the future of humanity, Yoneda requests a one on one conversation with Mirai. Mirai agrees, and Saki, Temari, Nakaumi, and Yumiki depart... leaving Mirai, Yoneda, and only Hoshi to observe the events. Yoneda is attempting to prevent the birth of the next God for the sake of the future he imagines for humanity.
With the whole world watching, in order to defeat Yoneda, Mirai demonstrates his resolve.
This is the first I'm hearing 
of the 999-day time limit
هذه أوّل مرةٍ أسمع فيها بارتباط
الحدّ الزمنيّ ذي الـ 999 يوماً
Dass das 999-Tage-Limit der Gotteswahl
mit Gottes Lebensspanne zusammenhängt,
Non avevo mai sentito che 
il limite di tempo di 999 giorni
É novidade pra mim que os 999 dias da escolha
têm a ver com a expectativa de vida de Deus.
