Hattori tells Rei about something that happened in his past that ties in with the Anonymous Case and in return, he wants her to try to get Makoto to talk.
So I figured the bad guys that
Hibiya mentioned is the Kujo Family.
Mit den „schlechten Menschen“,
die Ida erwähnt hat,
Les mauvaises personnes
dont Hibiya parlait
तो मुझे लगा कि जिन बुरे लोगों का
हिबिया ने ज़िक्र किया था वह कुजो परिवार है।
