Young Karibuchi Hikari is the little sister of Karibuchi Takami, a famous witch who fought against the Neuroi in Europe. Hikari is a hard worker with a lot of stamina, but she lacks her famous sister's magical abilities.  When she gets the chance to go to Europe and fight alongside her sister, she gladly volunteers, but first, she'll have to prove herself by competing with another student at her school.
There's no telling when our country 
will become a war zone.
فلا أحد يعلم متى قد تُصبح بلدنا منطِقة حرب
Es ist ungewiss, wann unser Land
zum Kriegsschauplatz wird.
La guerra puede llegar
en cualquier momento.
La guerra puede llegar
en cualquier momento.
Cette guerre pourrait arriver
sur nos terres.
Un giorno questo potrebbe diventare
un campo di battaglia.
Não há como sabermos quando nosso
 país virará uma zona de guerra.
