22 years ago our world was invaded by demon forces, which plunged it into long and brutal war. After few years of fighting, humanity managed to push all of the demon army back to the portals they came from, finally ending the conflict by destroying them. World was however irreversibly scarred by the conflict, one of such reminders of it in presence of half-demons, an offspring of demonic soldiers forcing themselves on unwilling human women that were captured by them during the war.

Maya is one of such half-demons, a 19 years old girl conceived just before war end. Due to her demonic heritage she has faced discrimination and hatred her whole life, which moulded her into stoic and reserved individual, constantly hiding her emotions to shield herself from pain.

Now after nearly two decades of struggles and isolation, it seems that Maya has managed to finally find her first friend who isn't discriminating against her, you. As the only person to truly accept her, you have become her beacon of hope in dark world that seems to hate and despise her. So don't break her heart, please?
