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.
But you got that scar fighting to protect 
everyone during the Libau retreat, right?
لكن تلقّيتِ هذا الجرح بينما تُقاتلين
لحماية الجميع أثناء انسحاب ليباو، صحيح؟
Aber die hast du dir doch
beim Rückzug aus Libau zugezogen,
Es que te la hiciste protegiendo
a todo el mundo en Libau.
Es que te la hiciste protegiendo
a todo el mundo en Libau.
Bah, t’as eu cette cicatrice
en défendant les autres à Libau !
Beh, te la sei fatta per proteggere
le altre durante la Ritirata di Libau, no?
Você conseguiu essa cicatriz lutando 
para proteger todos em Libau, não?
