I Work as a Prosecutor in Tokyo Ghoul

I have traveled through time, and in the ghoul world, I am a human. Fortunately, I have a system, otherwise I would really be in trouble. Let's make some plans first. At least I will become a senior prosecutor. However, I was already a prosecutor when I time-traveled, but it was only second-class. It was an identity given by the system. What's my name? Hirako Ryuki. My brother has facial paralysis for ten thousand years. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
