North America: Let Chicago Be Free of Shameless People

[Gun battle + decisive killing + psychological behind-the-scenes + empathic reasoning for solving crimes] The South Side of Chicago in North America in 1990... This magical (abandoned) place... Can't contain it anymore! When God comes, you have to curse! The protagonist travels back in time to a young Karami from the South District, who turns out to be a college student majoring in psychology. What's even more damning is that the golden finger is actually a psychology skill! "Psychological suggestion, criminal profiling, empathy,... It feels pretty good." "Um..." "God help those who stand in our way!! (Let those who are against us wish themselves well!!)" "No more scoundrels on the South Side of Chicago!" "Let every corner of Chicago be bathed in the light of holiness!" "Let God say 'Praise Chicago' whenever he comes!!!"
