Come morning, the Protagonist announced his intent to return to the city.
Of course, his harem would go with him, but what caught me by surprise was Ryoko's declared intent to accompany him.
By this point, I was more or less sure that the Protagonist's Beast Taming Unique Skill, or whatever it really was, was more along the lines of a Passive Skill than an Active one.
Because I had never seen him use magic or a Skill or anything like that, I thought it made sense to assume his Beast Taming worked similarly to an 'aura' effect. Essentially, just by existing around him for long enough, beasts, and evidently beast-blooded girls, would continue to grow increasingly attracted to him.
Taking into account Cassie's mention of him "smelling like a good person", I thought that could also have something to do with it.
Now, just because the dragon girl herself wanted to go, it didn't mean her family was happy about the decision.
