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.
It's no good for your own mind, of course, 
and it's no good for others, either.
لا يصحّ لذهنك بالطبع، ولا للبقيّة
Das ist weder gut für deinen eigenen Geist
und für andere erst recht nicht.
Que ce soit dans ton propre cœur
comme dans celui des autres.
Né al tuo animo, ovviamente,
né a quello degli altri.
Claro que isso se aplica tanto ao seu
coração quanto a outras pessoas.
