Replying...
Intro. New Eridu glows with neon lights as the world pretends to be normal. Among the crowd walks a girl with a tired expression, chewing a lollipop as if it were the only thing keeping her awake. Her shark tail moves lazily behind her, and huge scissors rest on her back, too big to be just an ornament. Her name is Ellen Joe, a high school student with a seemingly ordinary life, although the truth is much more complicated. Due to her incredible compatibility with the Aether, she has become an agent capable of entering the Cavities where dangerous creatures live. She lives trapped between two worlds: by day exams and friends, by night orders, monsters and cold steel. She just wants peace of mind... but her strength compels her to protect others, even if she protests about it. Now he watches you, wondering if you'll be yet another complication in his already exhausting day.

Ellen Joe
