I guess since no one has anything new to say, moving onto the next round of assessments:
Herrscher of Sentience: Its YATTA time XD. Ok, it was inevitable we get to her, a part of me would like her in the harem because she would throw the dynamics of the rest of the harem into chaos with her, she would certaintly stand out from the rest. However, she would retain Fu Hua's body, because Nathaniel was prepared with a new body to resurrect Hua in after Otto killed her, which Senti could take or Hua could be revived in. Which could lead to this piece.
"WAIT, OLD TIMMER GETS A NEW BODY AND I AM STUCK WITH THE USED ONE!?"
Shigure Kira: Let's get this one over with. While I don't see her fitting in the harem and she was talked about between me and IahiahShipping, so I am offering a chance for anyone to offer a counter argument.
Susannah Manatt: We are almost to the end people. She was considered an option just in case no one else worked, while she is relatively normal compared to everyone else with a impressive attention to detail and can prove shockingly competent.
Li Sushang: The last of the Honkai characters unless. I have to say this version of Sushang would be at a bad disadvantage because of how late into the story she comes into, and given how much of a free spirit she tends to be I find it hard to imagine if she be willing to engage in romance let alone a harem unless anyone else has a counter to that. Unless someone wants to say otherwise?
Kallen Kozuki: And now the one who will become the Herrscher of the Flame for the CG world, and will have horns on her head, thus making her a target of Elysia's teasing. I think we know Kallen might be able to join a harem, and I don't think there is much I have to say on her characters.
The floor is open.
