Sealed Harmony

Siren, that is what people call her which appeared out of the blue when humanity struggled to face the portal that appeared within the peaceful 2065 that became the bridge of the monster of fantasy advancement of calamity. Derived from how stunning and beautiful her voice is, the heroes who fought bravely in the front lines are greatly buffed whenever they hear her song. When monsters of dreams become reality, there is nothing weird if awakened become a norm and so for the beauty to garner such attention. Yet, no one knew who she is because she only upload some of her songs online, before then never appear since, whereas her legacy kept being a foundation to be the wall to protect humanity. "Where is "Siren" when the portal becoming more uncontrollable?" "Her existence might boost the entire raid team so people start to hope that she might hear humanity pleads for help" "She might already be dead, or she lost her ability but regardless, even the little legacy she left already benefits us." "With such a beautiful voice, she might already look like a goddess from heaven now 8 years had passed, yet...it is such a pity right? 'Siren, you are dead and never exist and I will bury you like the dead person that you are.' I hope I can protect this secret until I die but, is it possible when humanities kept pleading her...name? No, humans are not such a weak race. They would fare just fine without her so I will pursue my own dream without getting tangled with my past. ...I hope so.
