Isuzu attempts to steal the Neo Durandal at gunpoint. But when he's confronted with the painful truth that he's the only one not "Universing" (=awakening to the Universe Sense), he leaves his family behind. And thus, Subaru and Isuzu part ways once more.
Now that he has the Neo Durandal,
he should grow far stronger as a pilot.
Ahora que tiene el Neo Durandarte,
mejorará mucho como piloto.
