Where do Honglian and Zhenzhi sleep?

Guren Ichinose's weapon is called True Day and Night, and the ghost inside appears in the form of Hiragi True Day, which is Guren Ichinose's former lover.

Hiragi chose a simple direction, that is, to become stronger and stronger, strong enough to create a world where she and Honglian can love each other. However, since she was born, a ghost has lived in her body, and so has her sister. In order to protect Shinohara, she absorbed the ghost of Shinohara into her body, and in order to separate the ghost from her body, she made the original ghost magic equipment using the information of Hiragi House and Bai Ye Church. In this process, she was gradually eroded by ghosts and gradually lost her consciousness.
