Miki Hokuto calls Coquelicot Manor, the Matsuzaki family’s boarding house, her temporary home. Her career as a physician is evident from the outset, with intentions to relocate and launch an independent practice—a plan revealed at her farewell gathering. Though Hana Matsuzaki proposes converting part of the manor into her clinic, Miki opts to pursue her ambitions elsewhere.

She frequently engages with Sora Matsuzaki and her younger brother, exchanging updates on Konan Academy’s happenings. These dialogues allow her to glean insights into the school’s social landscape and relay details about Shirō Mizunuma, the student council president. Miki proposes extending an invitation to Shirō for her farewell celebration, which draws a lively crowd of friends and associates.

Her academic brilliance shines through when Umi Matsuzaki stumbles upon her flawless final math exam during a cleanup of the Latin Quarter clubhouse. At the party, Umi hoists a commemorative flag in her honor, cementing their bond.

Miki’s connections include familiarity with Shirō’s older sister, a nuclear physicist, and she acts as a supportive presence within Coquelicot’s community. Her role involves orchestrating social bonds, discreetly nurturing romantic possibilities among peers. Though her departure signifies a pivotal transition for the household, her legacy endures through her interpersonal impact and the lingering echo of her scholarly excellence.
