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...
But if you want to fight, 
you have to get stronger.
لكن إذا أردتِ القتال فعليكِ أن تصبحي أقوى
Unter der Voraussetzung, dass du
an Stärke für das Gefecht gewinnen musst.
Mais si tu veux te battre,
tu dois devenir plus forte !
Tuttavia,
Mas se quiser lutar, terá
 que ficar mais forte.
