By: shiroi ema

Ruka is a knight sent to take on a demon army. Sex, magic, and strength are all closely linked, and given that he has no interest in getting down, he’s really just a glorified errand boy. However, after a dramatic turn of events, he discovers that he has extraordinary stamina that may be the key to becoming one of the world’s most powerful heroes.
The series combines battles, worldbuilding, elves, monsters, and comedy, making it a great choice for fantasy readers looking for an adult spin on genre staples.
