Hiroto and Kazami have made a small but very important improvement in their relationship. However, the Build Divers and the Resistance are now overwhelmed by the attack of the mysterious Gunpla known as "Seltsam." The pendant that Muran entrusted to Hiroto and the others seems to become a key to turn the tide, but… Meanwhile, May begins gathering intelligence at Magee's bar.
The old Hiroto is back.

Der Hiroto von damals ist wieder zurück, was?

Aquel Hiroto ha vuelto.
Il est comme revenu
à cette époque.
Allora è proprio tornato, l'Hiroto di quei tempi.
O velho Hiroto-kun voltou!
Хирото стал совсем как раньше.
