Arifureta Zero: Volume 3

A few months have passed since the battle at Andika, and the Liberators have spent some much-needed time resting. But when Miledi heads to a Liberator branch office with her newest comrade, Meiru, she discovers that the hidden village in the Reisen Gorge has been destroyed! She rushes over to the scene only to meet a mysterious man wearing a scarf. He introduces himself as Vandre Schnee, another user of ancient magic, and he says he's willing to join the Liberators, but only if Miledi and the others go to the demon kingdom, Igdor. Who is this mysterious man, and can they trust him!?
