I Start from Demon Slayer and Begin by Going on a Blind Date with Mitsuri Kanroji

Xiao Lin suddenly transmigrates to an unfamiliar world. After obtaining a System, he is told that he must first figure out what kind of world it is before he can start any missions. Being cautious, Xiao Lin decides to train himself before setting out on an adventure. Then one day, he meets a girl named Mitsuri Kanroji, and the two begin with a blind date.

(The male lead is called Xiao Lin. As for his full name, use your imagination and call him whatever you like! Everyone has their own ideas, and coming up with a name is just too hard.)
