Unlike Luna Kindred in the game... or even in the story, Theresa, the real vampire princess, possessed far more bug-like abilities.
If Luna Kindred in the story still had many aftereffects, such as losing control and directly entering a hunting state whenever she went somewhere crowded.
Then the current Luna did not. The current Luna could be considered an enhanced, optimized version of the vampire Theresa from the story—also known as Experimental Subject A-872.
The current Luna was Otto Apocalypse's ideal perfect creation, because... the Valkyrie Luna Kindred that the girl had become could achieve what Otto Apocalypse wanted: resurrecting Kallen.
In the game's... parallel-world storyline, Luna Kindred had resurrected Kallen, but... neither that A-872 nor that Kallen had been whole... it could even be called a disaster. That... Experimental Subject A-872 could not control her desire to prey on humans.
And kind-hearted Kallen would not have wanted to be resurrected in such a form, but... things were different now. The enhanced Luna Kindred did not have that uncontrollable urge to feed.
The only price was living on blood like a vampire... and she no longer feared sunlight, silver, or other vampire weaknesses.
At most, she was not very alert during the day, only becoming extremely energetic at night.
So... should she resurrect Kallen?
If she resurrected Kallen and made her live on blood... would she agree? Or rather... after resurrecting her, should she immediately meet and speak with her as Yae Sakura?
"This seems like a pretty good idea..."
After resurrecting Kallen, she could show off their love right in front of Otto Apocalypse!
Though there seemed to be a bit of a problem. For Otto Apocalypse... his obsession was resurrecting Kallen. Once Kallen was resurrected... even if she cheated on him, he might not care that much, right?
