Although Sis can't use Water magic, 
she can use Fortification magic.
رغم أنّ أختي لا تستطيع استخدام سحر الماء
إلّا أنها تستطيع استخدام سحر التّحصين
Sie kann zwar keine
Wassermagie nutzen,
Aunque no puede usar magia de agua,
puede usar magia de fortificación.
Aunque no puede usar magia de agua,
puede usar magia de fortificación.
À la place de la magie de l’eau,
Mia sorella non è in grado
 di usare la magia d'acqua,
Minha irmã não pode usar magia de água, 
mas ela pode usar magia de fortificação.
Сестра не владеет магией воды,
но зато ей подвластна магией усиления.
