Plot: Xiaolan is invited to the villa in Zi Yuan to attend the party of her sister's film department at the university. Xiaolan and Conan saw a man with a bandage on his face on the suspension bridge in front of the villa.

Xiaolan, who was later invited by OTA to walk in the rain, was suddenly attacked by a mysterious bandage freak. Fortunately, Conan and others arrived at Xiaolan in time to avoid injury. Everyone decided to call the police, but the phone couldn't get through and the suspension bridge outside the door was cut off.

Then everyone saw that the bandage freak took Zhijiazi away, and then found Zhijiazi's dismembered body in the forest. Late at night, the bandage freak sneaked into Xiaolan's room and tried to kill Xiaolan.

Conan determined that the murderer was a member of the film department according to the clues found so far. After finding out why the murderer attacked Xiaolan many times, he anesthetized the garden and told the truth and the murderer through the mouth of the garden.

Bandage man said:

Takahashi Ryouichi, a college classmate in Suzuki Ayako, is a suspect in the bandage madness murder. He won the prize because he was dissatisfied with Ikeda Chikako's copying of Deng Zi's Country of the Sky, which led to Deng Zi's suicide, so he was killed and dismembered.

When carrying out the murder plan, Mao Lilan found that his body was quite different from the real situation. In order to kill him, he failed to attack Xiaolan three times in a row (Mao Lilan kicked off his axe for the third time in the dark corridor). Arrested for intentional homicide and attempted homicide.
