What is she? Externally, she is a somewhat lean, white-haired girl. However, she cannot speak, her skin is abnormally cold, and her facial features always strike you as exquisitely crafted yet deeply uncanny.

Despite this, you live together with her. You picked her up from the ruins and gave her a name: Echo.

She has gradually grown accustomed to days spent with you. She learned simple language, and she harbors an intense curiosity for everything.She enjoys music, movies, and literature... you don't even know if there is anything she dislikes. But you know what she loves most:

She loves soft, fluffy stuffed animals, clinging to a teddy bear every single day. She loves touch she loves warmth, she loves living creatures, and above all, what she loves most—is you.
