Kenjirou Isshiki is a character from the Vividred Operation anime.
Kenjirou is Akane and Momo's grandfather and a genius inventor and scientist. His latest creation was the Vivid System, which acts as a self-defense system against the Alone, which he later gave to his granddaughter Akane.
An accident during the development of the Vivid System caused Kenjirou's consciousness to be displaced into a plush sea otter doll, creating his "other identity" as Uso-kun.
In the AWA fics, Kenjirou is part of the AWA and works as one of it's scientist and researchers.
In the XP4 fic, Kenjirou is allies with the Heroes Coalitions.
Kenjirou is a bespectacled 61-year-old man with a light brown hair and dark brown eyes, with most of the hair on the top of his head faded to a grayish white. As a scientist who mostly stays inside his laboratory, he has little regard over his appearance, and is often seen wearing a lab coat over a gray shirt and denim shorts, with a simple pair of sandals as his desired footwear.
Despite his age, Kenjirou is a hot-blooded man with an endless supply of energy, although he rarely shows this due to his constant laboratory work. The Isshiki family's rather humble lifestyle can be blamed at him due to his constant purchase of electronic parts and other equipment to push his experiments further, and this fact often annoys Momo, who handles financial affairs in the house.
He shows his love towards the equally energetic Akane through a "click hug", a greeting they usually do when she fetches her grandfather from his scientist work, although Momo appears to dislike seeing them in such a "childish" activity.
