Mugen no Ryvius EP5 - A Little Harmony

While learning how to operate and survive on the Ryvius, the crew aboard the saboteurs' ship prepare for their backup plan. The Zwei assign groups for certain jobs to make the operation of the Ryvius much smoother. However, Kouji and Yuki are placed into the same group and they are less than enthusiastic. Yuki's bitterness towards his brother, though, makes him take his anger on his brother, all while the Ryvius is being attacked. The Ryvius automatically defends itself by creating a well of immense gravity, destroying the ships in the process.
