Berserk of Gluttony (Light Novel) Vol. 2

Fate wants nothing more than to save Roxy from certain death in Galia, a death to which her fellow holy knights condemned her. As he follows Roxy's trail, he encounters a Galian girl he once met: Myne, who wields a black axe that eerily resembles Fate's own black sword. Myne agrees to help Fate fight the monsters between him and Galia--but once they get there, he must repay her favor in kind.
