My little sister is marrying an unprincipled dark magician... Okay, maybe he's a decent guy, but his brothers are definitely unprincipled! Necromancer-misanthrope, incubus-ladiesman and, of course, universal evil - the black ruler. And all three are so happy about the wedding that the thought inevitably arises: are the future relatives up to some trick? But it’s not for nothing that I, Agnes Erkli, am considered the best in defense against dark spells! And I won’t hurt my sister, and I will uphold family honor. If only the heart does not tremble and outrageous feelings do not interfere.
