The Build Divers decide to participate in a Battle-Random mission in which the matchups are randomly determined. Their opponent turns out to be a force called Hyakki, which includes Do-ji, against whom Riku won his first victory, and Ogre, who gave him his first taste of defeat. Riku's heart pounds with anticipation at the idea of assessing his growth by taking on Ogre, using the strength he's accumulated through his previous experiences. Meanwhile, Do-ji's own heart burns with desire for revenge.
In a facility defense battle,
،في معركة دفاع عن منشأة
Bei der Verteidigung einer Einrichtung
En una defensa de instalaciones,
En una defensa de instalaciones,
Quand on défend une installation,
In una battaglia di difesa di un obiettivo,
Numa batalha de defesa de um prédio,
Секрет миссий на защиту точек
