Bodach is Renkin Arthur's fairy companion, characterized by an easygoing and honest personality. She displays fierce loyalty and protectiveness towards Renkin, whom she introduced as exceptional and flawless. Bodach actively intervenes against perceived threats to Renkin, repeatedly warning about Dancho Arthur as a dangerous wolf and preventing lewd advances from other characters, notably a male Arthur.

Her interactions extend beyond Renkin, including sharing a pocky stick with Dancho Arthur during an onsen episode. Bodach experiences strong reactions to stimuli, such as a nosebleed upon witnessing Fairy combine. She also dreamed about Renkin during an instance where they were physically tied together.
