Moe Academy: Double Naiya Blackened Urala and Went Crazy.

[Travel+Two heroines+Blackening+Redemption+Sister bond+Invincible flow] Ulala burned her life to summon the Holy Sword of Sorey, preparing to die with the Dark Emperor. Just as she was about to disappear, the sky tore apart. Another "her", covered in blood and with scars on her face, descended from a hellish parallel time and space! Uknana in this world is gentle and protective: "Don't be afraid, sister, sister is here." But her eyes were cold, and she grabbed the Dark Emperor by the throat: "Dark Emperor! To destroy my world and kill my sister, I will use your clone interest first!" All the cute knights were shocked: Who is this Princess Naia with murderous intent and explosive combat power? ! She is an avenger who crawled out from a mountain of corpses and a sea of ​​blood, and a shadow princess who has lost everything and is left in despair. She hated this peaceful world, and even more hated the well-protected, naive and weak "self". But when the dark forces in this world came back again, she stood in the forefront again and again, killing them like crazy! "Shut up! I'm not here to save you," she wiped off the enemy's blood on her face and looked at her trembling self: "But this world... Can only be destroyed by me!" Uknana opened her arms and tried to hug her two sisters: "It'll be nice to come back..." But she burst into tears and pointed the tip of the knife at her loved ones: "Don't touch me! You are not her... My sister has died in my arms long ago!"
