Naofumi follows the slave merchant to his store, where he looks for a partner to act as his sword. But all he has the money to buy is a diseased demi-human girl named Raphtalia, whom he then forces into an incredibly harsh battle.
Training one is no different 
than upgrading my shield.
تَدريب أحدهم لا يختلِف عن تطوير ترسي
Es unterscheidet sie also
nichts von meinem Schild.

Será como mejorar el escudo.
Je le traiterai
comme mon bouclier.
Tra addestrarne uno
e potenziare lo scudo non c'è differenza.
Treinar um não é diferente
de upar meu escudo.
Они лишь вещи,
ничем не лучше щита.
