“A Jibakurei Cat Yo-kai. He is someone who was once in contact with many humans, and was even recognized in the Yōmakai. Ever since he parted with his favorite human, he has become a wandering Yo-kai."
Yo-kai Medallium biography
“A cat Yo-kai who is famous in the Yōmakai as a "Yokai who touched many humans". He can't remember much of the past, but for some reason he likes the human world, so he's been living there for a while."
In his everyday Lightside form, Jibanyan is a Cat Yo-kai similar to his appearance from the previous series. His color scheme is less saturated, he is slightly taller, and his eyes have thin, vertical pupils, with dark shadows. His tails are also shorter, his fur is shaggier, and his paws have visible digits now.
In his combat Shadowside form, he is a lot taller, more slender, and muscular, similar to Rubeus J. His expression is more fierce, baring his sharp fangs, with his pupils having disappeared, and his eyes glowing with an ominous yellow.
The fur on his paws and shoulders stands on end more, and the wisps on his tails burn stronger.
Unlike his previous form, he is very standoffish. This is shown in the movie, where he attempts to scare Natsume and the others by kicking a big or small wheel from a truck he smashed before.
In the Shadowside anime, his personality is similar to a tough guy's. In SS011, it is revealed that he lost his memory. Making him confused about his hatred for trucks and his love for chocolate. Every time he sees a high school girl, his heart turns softer. This is because of Amy, his former owner's care for him.

Yo-kai Watch Shadowside animation series
Jibanyan continues to appear as one of Natsume's Yo-kai friends. Due to his strength and skill, he appears to be her Yo-kai of choice when it comes to battling.
In SS011, it is revealed that at some point before SS003, he encountered and saved a girl named Miho from Shinigami. Miho turned out to be Amy's daughter and meeting her again restored Jibanyan's lost memories of her and how he became a Yo-kai, briefly reverting him to his previous form. After this, Amy asks him to do one thing for her, which was accompanying her while she rides her bike (just like in EP025). Instead of his previous form, he is on his Shadowside form while doing this.
Meanwhile, the pieces that were shot off of Jibanyan's body during the battle with the Shinigami formed the Yo-kai Junior.
In SS016, he was summoned to deal with Gesodrill but refuses to battle due to his hatred of water.
Also in SS020, he was summoned to deal with Filmlin but ended up in illusion where he drown in the big water pot, much to his hatred of water.
