Hubert is the French localization name for Makoto Aido, a resident occupying room #1 at the Hidamari Private Boarding House. He is one of four male students boarding with Kasumi Kishimoto's aunt. Within the series, Hubert serves a minor narrative role, primarily functioning as a source of comic relief. One episode of the live-action drama adaptation, which adapts his name as Makoto Nakaoka, depicts him as a prodigy in medical studies.
