5 Valkyrie survivors in total if you include Takeru, it makes 6. After the event at the Original Hive, they all transfer to the Fuji Instructional Corp.
@@huycan9518 No I said that except for the second opening which is amazing (I listen to it every day) The rest of the anime is average or even bad in some cases. But that doesn't change the fact that there are some scenes that are very well transcribed and that are incredible.
