So the restriction on switching Valkyries based on affection was added by you, Ai-chan?
Ai-chan: Not at all, Boss. Don't wrong Ai-chan. The reason I could remove the restriction was only because, after arriving in this world, Ai-chan lifted some restrictions. "..."
Listening to Ai-chan, Luna began recalling Ai-chan's origins. Although Schicksal's technology was advanced, it still could not create such a "great" artificial intelligence as Ai-chan.
Ai-chan's true identity and origins traced back to a robot left behind by the civilization of the previous era, discovered during an expedition into ruins.
Back then, the robot guarding Judah had fought Theresa fiercely. In the end, it ran out of power and was defeated by Theresa. That robot was Ai-chan. Theresa took the powerless Ai-chan home and made her the battleship's control AI.
It was precisely because Ai-chan was an artificial intelligence left behind by the previous civilization that she possessed such high intelligence and human-like qualities.
However, this Ai-chan of hers was not an artificial intelligence left behind by the previous civilization. She had evolved from her account system through some mutation, though she had no idea what exactly had caused it.
At least for now, this Ai-chan was pretty good.
Luna then looked over the mission reward a few more times. Basically... she could now switch to any Valkyrie she had unlocked. She was no longer limited to three times per world, and she could repeatedly switch into the same Valkyrie.
However, the duration for which a switched Valkyrie could exist could not exceed the time the newly unlocked Valkyrie had existed in that world. In other words, in this world... the time she could use other Valkyrie identities could not exceed the time Himeko had existed.
That was easy enough to understand, and she had no objections.
