Infinite Ryvius - Season 1 Episode 2 Unnecessary Things

As the condition of the Liebe Delta Station deteriorates even further, we start to see the intentions of the saboteurs. In an attempt to save everyone aboard the station, the Zwei evacuate everyone into the Rever and ready it to launch out of the Geduld. However, in order to prepare the launch in time, the remaining teachers purge what's left of the station to lower its velocity. In the meantime, Kouji and Ikumi are rushing to the Rever while carrying Faina who was injured duing the panic. They make it back in time as the teachers carry out the purge, sacrificing themselves in the process.
