Venn gave an affirmative nod to Rena. Watching Rena's exhausted face, his heart was having a complicated feeling.
Not all demonesses are evil and bad. Rena had kept her promise and her part of the deal and her personality attracted Venn greatly.
Unlike Erza and Rin, he truly admired everything about Rena, not just her lustful body.
Though he couldn't agree with Rena's unselfish act of sacrificing herself for the sake and prosperity of her clan, he was attracted to her kindness. Her intelligence and beauty was frankly unparalleled and her being family-oriented fits right up his alley. Her perseverance when giving birth to their child was inspiring as well.
During their love making session, he could tell that Rena wanted him to fuck her more. But sadly now, they are going their separate ways. This would probably be the last time they would see each other.
