What is the relationship between Jiuneng and Leica?

It's okay. Long-term integration with Leica is needless to say the role of reasoning. It is a TV cartoon adapted from Cheng Jingping's mystery novel of the same name. Leica is one of the personalities in girls with "dissociative identity disorder". When the mental condition of Chiba girls deteriorates, Leica will dominate the body of Chiba girls. Leica will disappear when the girl's mental condition returns to normal. In the play, Chiyoko's real identity is an old friend who can be fixed for a long time, but it has nothing to do with Leica, so it has nothing to do with Leica.
