Based on the cover of the first Kuitsume Youhei no Gensou Kitan novel, you might expect to find a variation of Berserk‘s main character as its protagonist… and those expectations would be fulfilled. This series is basically pre-demon invasion Guts if he happened to live in Goblin Slayer‘s setting.
It is not obsessed with goblins however, so each novel (so far) features a different sort of antagonist ranging from undead, to slimes, to fae. What binds everything together are three ongoing background plots: The evolving relationship between the two main characters, the periodic appearance of unsealed dark gods, and the mystery behind Loren’s abilities/training.
It’s a lot of fun, mainly thanks to the interplay of the characters’ personalities. Only thing I can complain about is the localization. This is a series that would’ve greatly benefited from leaving the honorifics alone instead of trying to translate them; each “Mr. Loren” causes physical pain.
