The Akashic Records

When Loki heard the system's voice he was stunned for a few seconds before he was able to respond. 

"Shera, are you Shera?" Loki could not help but tremble as he heard that familiar voice of hers. He knew it was a long shot but what if. 

"I'm not this Shera person. What you're hearing right now is the voice of the person that you trust the most in the world." 

When Loki heard that answer his killing intent started seeping out of him. His mana started to surge outward making the nearby bookshelves tremble. Even though the voice in his mind had no shape or form Loki looked like he was ready to kill it. 

"How about you don't do that?" Loki's tone was lowered which made him sound like he was growling. 

"Hmm, If you agree to activate the system then I would think about changing my voice." 

"Then disappear from my mind. I do not need a system, and I don't need some system that taunts me using my dead sister's voice."
