World's End Harem - Fantasia Vol 12

Dang, Retta sure became strong, although still a little weak; he has the potential that Arc does. He just having one girl is already pretty strong, imagine him having multiple like Arc, he will become stronger than Arc. Yet, it is only in terms of magic anyway, compared to Arc's close-range strength. Arc, just having his sword alone, was enough to let him win against the Iteshia king. Definitely going to find out in the next volume.
