Got to love those background character waifus. Waifus who aren’t huge parts of the story, but they still leave an impression on you enough to make you horny. Well, Aoi’s one of those characters. Always helping the boys when they get injured and bringing them back to health. But, I wonder what she does in her free time? I guess this NSFW audio from Ruby will tell us about that.

Aoi’s Demonic Training

With more audios to come, you can donate to her Patreon for this audio and more upcoming goodies.

What did you think of the audio? Would you like Aoi to patch you up? What character would you like to hear Ruby voice next? Tell us in the comments.
