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.
Um, Mr. Hiroto. Have you ever
fought an underwater battle?
سيد هيروتو، هل سبق وخضت معركة تحت الماء؟
Sag mal, Hiroto. Hast du schon mal
Unterwasser gekämpft?
¿Has peleado alguna vez
bajo el agua, Hiroto?
¿Alguna vez
has peleado bajo el agua, Hiroto?
Hiroto, tu as déjà combattu
en milieu aquatique ?
E lei, signor Hiroto, ha mai combattuto sott'acqua?
Ei, Hiroto-san... Você já
lutou debaixo d'água?
Слушай, Хирото, ты когда-нибудь
сражался под водой?
