A Sacrifice or Ploy?

After they separated for the second time, Felix's expression turned solemn. He told Asna about what just happened and how if it wasn't for Lilith, he would have been forced to blow her soul to rescue her.

Then, he asked with a serious tone, "Do you feel any change within you? I refuse to believe that Lilith has sacrificed her life for your sake."

"Hmm, nothing?" Asna shook her head, "If she has done something to my soul or core, I would know it."

"I see..." 

While he trusted Asna's words, he still refused to accept such a turn of events. He would rather believe in the universe ceasing to exist all of a sudden than accept Lilith's sacrifice.

"You said she was able to use my core-based defensive abilities." Asna analyzed thoughtfully.
