Jibanyan was originally a normal red cat, named Rudy who was owned by a teenage girl named Amy. They had a strong bond before Rudy got run over by a truck, causing Rudy to turn into a Yo-kai.

Rudy thought she would be great, but as a cat he was unable to tell her. When they went on over to the intersection, it turns out that Amy was supposed to die instead of Rudy, as chosen by the Yo-kai resembling grim reapers.
When Amy was about to get hit, Kin and Gin appeared before him, and told him they did this so Rudy could have a second chance, and he can change the outcome, in order to separate him from Nate. Rudy refused the offer and rammed into Amy, causing Rudy to die and Amy's life to be saved. It also turns out that Amy was calling herself this out of shame for what happened and held tight of Rudy's mangled corpse in tears.
When his spirit ascended from Rudy's body, he called out Amy's name and bids his farewell while Amy notices him from behind. After realizing that, he reminded Amy to pursue her dream of becoming a fashion designer. Rudy then went back to being a Yo-kai, and returned home to Nate.
