Charles coughing out blood

"Enigma…" Varian confirmed his guess.

From what he learnt of her so far, she was special.

She could hide from the Abyss' Will.

Her strength reached a level where she could slaughter everyone in Astor Clan's banquet including level 8s.

She could also sneak into the Demon Abyss and kill their princes without alarming the Archdukes.

From the way Charles' yelled her name with utter rage, he could confirm that she was Roxana's killer.

And the specialties she showed so far...she was likely a Hybrid, whatever it meant. 

So a year ago, Enigma was able to sneak in and out of guardian islands. She was also a level 8 or maybe level 7.

After coming to a conclusion, Varian looked at Charles outside and squinted his eyes.

He didn't care about how Charles' was feeling.

"Boo, this book can't be opened by unauthorized persons, huh?" Varian asked picking the red journal.
