Reborn: A Delta Force Soldier’s Detective Conan Journey

A Detective Conan fanfic with a System, but it's Delta Force.

Conan: “This member of the organization always has incredibly advanced weapons. Good thing he's on our side.”

Gin: “He always has all kinds of advanced weapons, and he's good in a fight and with a gun. I just wonder when he'll give me a set of advanced gear.”

Ai Haibara: “He's actually a pretty nice guy, but sometimes he's too childish and often makes other people clean up after him. Still, when he got caught, Gin really did come to bail him out. That's a miracle in itself.”
