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.
If I want to live, I have 
no choice but to fight!
!إذا أردتُ الحياة، فلا خيار أمامي سوى القتال
Um zu überleben,
müssen wir kämpfen.
Para sobrevivir tengo que pelear.
Para sobrevivir tengo que pelear.
Il faut se battre pour survivre !
Se voglio restare in vita,
non ho altra scelta che combattere!
Se eu quero viver, não
tenho opção a não ser lutar!
И если я хочу жить…
придётся бороться!
