Kyoka has a pragmatic, unenthusiastic, blunt, and teasing personality that is mostly shown to those she finds irritating, but she's usually nice and friendly. Jiro hates being tickled herself, although if the other girls are engaging in a tickle fight, Jiro would occasionally like to join in and show them who's truly the best. Despite her earphone jacks being insanely ticklish, they are also great for tickling others. Especially moving them back and forth between sensitive toes.
