Impossible together

Haru is the most popular detective known. Almost everyone knows his name. Is it because of his kind personality? Is it because of his good looks? Or maybe its because of his incredible intelligence. He solved every case given to him and catches every person he's after without fail. He can solve absolutely any case even with just a single clue. No matter how difficult the case is he can solve it.

One day his boss gave him an almost impossible case. There was a group full of murderers that were on the loose and probably the reason why so many people are missing. His boss also gave him some of his other best detectives to come and help! So of course with all the clues he can get Haru and the other detectives tracked down the murderers and was on his way to catch him.

Him and the other detectives found the killers but then got captured by them!
Do they kill the detectives?
Do the detectives escape and arrest the killers??
