Main Characters
Jinpei Jiba
Voiced by: Mutsumi Tamura
- Alliterative Name: Jinpei Jiba.
- Anime Hair: He has large tufts of hair shaped like cat ears, reminiscent of Jibanyan.
- Animal Motif: "Can a cat be a hero?" Duh. Even without taking the Title Drop and the fact that he's clearly based off Jibanyan into account, his hair, his penchant for naps and the ears and tails in his hero suit will surely clue you in. If that wasn't enough, he literally was a cat in a past life
- Bratty Half-Pint: While well-meaning and good-hearted, he is also cheeky, mischievous, brash and impulsive.
- Death by Irony: Inverted. When his mother was pregnant with him, a lightning bolt struck a traffic light startling a woman and making her let go of her stroller. His mother leaped into action to save the child from the falling traffic light, but was severely injured herself in the process and rushed to the hospital. This reflects how Jibanyan saved Amy from getting hit by a truck while crossing the street. For extra irony, his mother is Amy's daughter.
- Fiery Redhead: Downplayed. He has red hair and, while his temper does not run near as hot as Mera's, he does have a bit of attitude.
- Idiot Hair: He has a cowlick sticking up at the top of his head, which beffits his goofball nature.
- Keet: Chipper, hyperactive, and loud.
- Likes Older Women: Says this this word for word and has a crush on Enra much like Kyubi. Although he's willing to keep his options open.
- Reincarnation: Episode 38 confirms he's Jibanyan.
