The unscientific detective in Conan

God made a joke on Fujino. When he woke up, he traveled through the world of Detective Conan and became a high school detective who inherited a four-story building after his parents died and relied on commissions to make a living.
Just when he was at a loss, a professional system was suddenly bound.
From then on, he started the road of becoming stronger through krypton gold.
…………
May I ask, as a detective, why do you have so many skills?
Fujino: Let’s just say, isn’t it normal for a professional detective to learn professional skills?
