Meanwhile, Yure and Numi are busy assembling a new giant weapon, the Gravitational Beam Emitter, designed by incorporating Gauna placenta into the structure. During a joint exercise, Mozuku pilots Tsumugi while Nagate pilots Tsugumori Custom both at high speeds and in synchronization. Nagate later searches for a new house closer to Tsumugi's chambers, from which Tsumugi can easily visit him by sneaking her probe through the pipe network. Once he finds a suitable home, he invites Izana to move in with him as well. The trial for the Gravitational Beam Emitter proves to be a success, as it easily pierces through a dwarf planet. However, it is overlooked when the weapon begins to sprout tentacles at its base, which spread in the direction of the power cables.
