Kurogane no Linebarrels episodes

The JUDA Corporation is now responsible in holding back the launch of the Spheres installed. However, Yamashita has a different mobilization unit out, after receiving a letter designating him to fulfill a special duty surrounding a secret reunion around the base of Mount Fuji near the Aokigahara Sea of Trees. It is there and then that Yamashita must face off against Moritsugu. Meanwhile, the rest of the JUDA members are shocked to that Kiriyama is still alive, as he demonstrates his newfound power in an attempt to obliterate them.

Kouichi sees a powerful Moritsugu before him, after seeing a wounded Yamashita near him. Moritsugu prepares himself to show the members of JUDA their inexperience and lack of power. Unable to gain enough power and strength against Moritsugu, Kouichi is left almost helpless. Linebarrel struggles for power as Vardant ensues in a violent battle. Later on, Kato reveals that Kizaki is his sister, as well as how he developed the Kato Organization. Kato then proposes the JUDA Corporation to join forces with the Kato Organization to assist in the prevention of an enemy invasion arriving from an alternate dimension.

The JUDA Corporation and the Kato Organization prepare to defeat the earth against the upcoming enemy invasion led by Masaki. Kouichi and his Linebarrel take it upon themselves to drive the invaders into the space-time continuum and back into their respective dimension. Kato sacrifices himself in battle, protect the rest of the group. As Kouichi and his Linebarrel blast off into space, Kizaki initiates a surprise attack against the infiltrators. However, this attack eventually would cost her life.

Due to Kizaki's death, Kouichi goes berserk and showcases the true and ultimate form of Linebarrel. After a failed attempt to send the invaders back to their dimension, Kizaki appears to Kouichi in spirit form, telling him never to give up. With that mindset of motivation, he is about to destroy one of the enemy warships. However, this results in an instability of the space-time continuum between dimensions. Kouichi makes the choice to go inside the rift, and the rest of the JUDA members send their D-S.O.I.L. energies of their Machinas toward Kouichi, in order to save the world. Kouichi is able to return back from the rift, and Kizaki has been revived from Linebarrel.
