Events
Jonouchi tried showing off his yo-yo tricks in school, including long sleeper and parade the pooch. However his classmates recognized the latter as him just giving walk the dog a fancy name and laughed at him. In a desperate attempt to impress his classmates, Jonouchi tried performing loop the loop for the first time. He swung the yo-yo in all directions, causing people to run for cover and it resulted in him being tied-up by the string.

Nezumi told Jonouchi to stop fooling around, as he had developed a dislike for yo-yos after being mugged by people using yo-yos as weapons. Jonouchi offered to get revenge for him if he could take him to the attackers. However, Nezumi was secretly working with the yo-yo gangsters and was planning on leading Jonouchi to a trap.

Nezumi took Jonouchi and Yugi to an abandoned warehouse, where they were ambushed by Hirutani's gang. The gangsters trapped Jonouchi in a yo-yo murder net while they hanged Yugi by his Millennium Puzzle necklace from a hook. Hirutani gave Jonouchi the choice to rejoin the gang or watch his friend die, but Jonouchi pushed through the swinging yo-yos, taking several hits and saved Yugi.
