On the topic of floofs, warn me if I somehow missed a change, but: the first time you choose to share essence with Kiyoko, I wish there was even a short bit at start in case you're using ghostlight. Something like "Hey, I don't have a real dick, does this work to share essence?" "My senses tell me it is the real deal. Might be something with my spirit lacking body." or something.
Just, anything to reduce the cringe of her crying out about it being a real cock - afterwards, I don't feel it would need to be mentioned again? Aside from her not noticing champion having also lady bits to play with, this always pops up in my head when I consider the cons against progressing her story.
