^I don't think so. The whole point with the Body Hakunon was so that Altera could have a distinct and separate relationship with a version of Hakunon that was a blank slate and has no attachments to Nero or Tamamo. Altera has a relationship with body Hakunon alone, and body Hakunon has a relationship with Altera alone. Then they both died together. I think that was a pretty fitting way to end their story.
You've made me remembered the most important part of the 3rd arc, and I was a fool to forget such a thing. Thank you so much for that. Anyways, just finished Rider's sidestory and the ending was unexpected, and it somehow made me craving for a Hakunon x harem. Don't be mistaken; my favorite is still Hakunon x Nero, but there's something about a yuri harem that made it very appealing.
