My name is Lin An. I traveled to this world five years ago and obtained the Richest Man System. After I spent three years completing the task and became the richest man in China and the boss of the underworld, the system disappeared.

After a trip to Japan and a meeting with the leader of the Yamaguchi-gumi, I discovered that I had traveled to the world of "Detective Conan"!

Hehe, Xiao Ai, here I come~(～￣▽￣)～!

My name is Haibara Ai, and my real name is Miyano Shiho. After taking APTX4869, I unexpectedly shrunk. On the way to Kudo Shinichi's house, I fainted. Fortunately, a handsome older brother saved me.

He gave me a sense of security that I had never had before, but I was afraid that Brother Lin An would be implicated in the Black Organization because of me.

But I can't bear to leave him. I think I'm a little bit in love with him?

No, this big brother is so gentle to me! I really like him!

Brother Lin An, I want to be your girlfriend! ヾ(*′▽'*)ﾉ!
