Subaru and Itsuki face off against Arc Ruler Erde in a two-on-one battle. But who exactly is this guy? And why is he so certain of victory, claiming that he knows all about the pair?
I... no, we were created to protect the Arc.
صُنِعتُ... لا بل صُنِعنا لحماية الآرك
Ich … Wir wurden erschaffen,
um Arc zu schützen.
Io... no, noi siamo stati creati
 per proteggere l'Arca.
Eu... Não... Nós fomos
criados para proteger o Arc.
