well then
possibilities are heat of the moment in battle spurring such emotions, a monster influencing her, or yandere ara ara personality showing itself
@CountryMage TBH, he could have just given it to her. He did sell a skill 'ball' before, no reason to use his unique skill just to hand out skills he already made.
@CountryMage Sorry, what I meant was that we know he can hand over skills without editing other peoples skills. Meaning, there's no reason for him to 'install' it in Aine. Just make it on himself and hand it over to Aine, no magic orgasm weirdness. This is all a moot point though, since he specifically mentions 'installing' it.😄
@cor3zone then you misunderstood my second sentence, and don't remember that Cecyl made similar orgasm sounds, when installing the Demon Language orb (putting the orb into her back). Repeat : Rare means he made it by himself, but he installed it in her, which is still kind of lewd.
@CountryMage Yeah, I know he installed it, and Cecyl's earlier reaction to 'installation'. I'm just saying there was no reason for him to install it, that we know of at least. Other people can learn skills just fine normally, just grab the ball and do it on their own. Maybe it's different for slaves of something, I dunno.
