Kamonohashi Ron no Kindan Suiri

Ron Kamonohashi was the most gifted student in the history of the elite detective academy BLUE before a mysterious incident got him expelled and permanently barred from investigative work. Five years into his isolation, police detective Totomaru Isshiki seeks his help with a case the department cannot solve. Ron's ability to read a crime scene remains extraordinary, but his ruined career hides a far more dangerous problem.

Whenever Ron corners a culprit, a mysterious condition can drive him to compel that person to die, and he cannot stop himself once it begins. Totomaru, unexpectedly, can. Their partnership is therefore as necessary as it is strange: a brilliant detective forbidden from investigating and a well-meaning officer who lacks genius, each possessing exactly what the other needs to pursue the truth without turning justice into another death.
