Hikari and her sister are off for Europe.  But their plans are interrupted when the Fusou naval fleet is struck by a newly emerged Neuroi nest.  It's up to Takami to defend the fleet against this unexpected threat, but she's overwhelmed by the sheer number of enemies.  When she uses a dangerous technique to stave off the foes, it's up to the inexperienced and underpowered Hikari to protect the fleet...
My sister told me she wanted to defeat 
the Neuroi and bring peace back to the world.

وإعادة السّلام إلى العالم
