Freddie, an inhabitant of the planet Eldora, sets foot inside a ruined temple, carrying with him a book he accidentally discovered in a storage room. His curiosity leads to an encounter with Hiroto and the other Build Divers, and nobody could imagine what will result from this beginning...
We'll be done for if we can't fight back
when the One-Eyes attack, right?
سيُقضى علينا إن لم نستطع المُقاومة
عند هجوم ذوي العين الواحدة، صحيح؟
Na, weil die Einaugen uns auslöschen,
wenn wir nicht kämpfen.
Si nos atacan los Uniojos,
tendremos que pelear.
Si nos atacan los Uniojos,
tendremos que pelear.
Si les Cyclopes nous attaquent,
il faudra se défendre.
Se i Monocoli dovessero attaccarci, 
non avremmo altra scelta che combatterli, no?
Vai ser o nosso fim se não conseguirmos
lutar contra os Um-Olho, não vai?
