Rules researcher Lin Shen transforms into a strange NPC and gains the ability to tamper with the rules, but every time a rule is changed, a piece of memory is lost.

Until she discovered that the investigator who always left hints in the rules was the fragment of her missing sister from her previous life. And the system is the biggest weird thing.
