Lovely Princess react to Athy as Kiana//AU//more info in desc.

Au: This happened when Athy died in her first life. People came in taking her Obelian DNA and Mana the moment she died. With her DNA, they merged it with Kiana Kaslana's DNA. But Athy remained dorment until Kiana eventually learned that Athy is a part of her. While Kiana was enjoying her life and Athy making sure nothing bad happens to the both of them. Siegfried noted that Athy is a part of her and knows she's harmless but was wondering where she came from but nonetheless he cared for the both of them. That's when Sirin comes and controls Kiana and Athy, leading Siegfried to suppress the herrscher personality including Sirin. Himeko came and released them both. Athy was free but she remained with Kiana. And in turn she and Kiana worked to together to defeat Aeternitas/Anastacius. They both reversed time but with the cost of Athy's memories. And the WMMAP plot continues....

I hope it's understandable(sweating intensifies)
