The boy soldier next to the famous detective

Jonah, a child soldier, somehow transmigrated into the world of a famous detective and was adopted by Eri Kisaki by chance.
Jonah, who had thought he was finally about to start a new life in a peaceful world, fell into deep thought as he looked at the news from Mihua City.
Jonah felt that, in any case, a city where an average of three people die every day, bombings happen every now and then, and armed helicopters occasionally fly overhead, could hardly be considered safe.
Good news: they are no longer child soldiers and no longer need to go to the battlefield.
The bad news is that this place is not much better than the battlefield, and you also have to abide by the law and can't use a gun.
Good news: I can still secretly get my hands on a gun.
The bad news is that the people around me are more wary of me than they are of criminals.
Ran Mouri: "Jonah, you didn't bring a dagger with you today, did you?"
Conan Edogawa: "Jonah, I beg you, please don't hit the criminal after he's already confessed!"
Ai Haibara: "Jonah, you're not really going to give me a grenade as a gift, are you?"
