In "Detective Conan", Xiao Ai is a relatively aloof woman. Her aloofness stems from her tragic upbringing. Haibara Ai, formerly known as Miyano Shiho, her parents were assassinated because they disobeyed the arrangements of the dark organization. Xiao Ai and her sister Miyano Akemi were taken to the black organization when they were very young. Xiao Ai has been forced to engage in the research of biological agents. She has no love or care. She can only be controlled by the organization like a working machine. Her whole person is cold.

However, she didn’t want to live such a life, but she couldn’t escape. It wasn't until she discovered that the potion she developed could shrink people, and her sister was killed by a dark organization, that she took the potion, shrunk and escaped. In this world, she has no relatives and is very lonely, so she puts on this thick coat of coldness. Later, she was rescued by Dr. Ali, and saved by the friendship of Conan, Dr. Ali, and the three little boys of the Young Detective Corps, she slowly opened her heart.

It’s just that the long-term aloofness has formed a habit, and her aloofness remains unchanged, but this aloofness contains the desire for life. When the members of the black organization appeared in front of her again, the fear of the organization in her bones made her so scared that she wanted to give up her life. However, Conan, Akai Shuichi and others worked together to rescue her. She was back in a safe world.

In such a safe and secure environment, although Xiao Ai does not change her aloofness on the surface, she is gradually changing. She can become a crazy little fan girl in order to chase stars, she can risk herself for her friends, and even try her best to overcome her fear of dark organizations. It can be said that the silent care and dedication of Conan, Dr. Ali and others saved Xiao Ai.
