Kitton serves as the apothecary and herbal expert within his adventuring group, while also identifying as a farmer. His background is clouded by amnesia, with unverified suggestions of descent from a royal lineage known as "The Kittons."

He possesses extensive scholarly knowledge, meticulously documented in a mini-picture book he curates. This book acts as a vital quest resource, detailing creature weaknesses like the momonga's vulnerability to fire, the koronet beetle's breeding season behavior, and the magman's weakness to water. It also identifies parasites used by dark mages for mind control.

Notoriously avoiding baths and haircuts, Kitton maintains a reserved demeanor but proactively supports the team by applying his research to navigate dangers. An encounter with the witch Zen during an OVA storyline yields a magical mirror that responds only to his touch, hinting at his latent royal connections. This mirror later unlocks hidden passages within a white dragon's cave, bypassing traps.

Gradual clues about his heritage emerge through artifacts like the mirror across official media, though his amnesia persists. Light novel titles such as "Shin Fortune Quest (2) Kitton-zoku no Akashi" and "Shin Fortune Quest (10) Kitton no Kesshin" suggest expanded exploration of his lineage and resolve within the narrative universe. His role consistently focuses on applying academic knowledge to practical challenges as the group's living encyclopedia and herbal specialist.
