Mizuki Usurai

She is tall at 171 cm and has short blonde hair. Her everyday look is boyish, often pairing a hoodie with her casual outfits.

She carries herself with energy and presence. Her style matches her assertive, on-the-go leadership in the club.

She is bright, lively, and bold, often acting with grand gestures and decisive moves. She is also caring and considerate, with a knack for looking after others.

She is people-oriented and fearless in approaching unfamiliar adults for negotiations. Her likes include friends and old movies, and her dislikes include her grandmother and thinking about the future.

She is in Class 2-1 at Sumomo Hill High School and previously attended Naruno Middle School. She was born on January 26 and is from Mibasho City.

Although underage, she lives alone in a seaside apartment supported by remittances. She comes from the founding family of the Raiten Group, a major conglomerate.

Her grandmother Mayumi Usurai upholds a male-heir-first view and neglected her, which led Mizuki to delinquency in middle school. Her parents follow Mayumi’s orders, creating a severe rift, and she was effectively sent out to live alone.

Her relationship with her brother Koki Usurai was thin for years but began to mend after a confinement incident. She only entered the broadcasting path in high school, yet her voice talent quickly drew attention from top competitors nationwide.

She excels in competitive reading, delivering emotionally rich, precise performances. Her voice control and interpretive depth make her a standout in the reading division.

She has impressive initiative and negotiation skills, even persuading adults to make logistical changes. As club president, she organizes people and resources with confidence.

Hana Haruyama: She discovers Hana reading on Junari Island and invites her to join the broadcasting club. She arranges for Hana’s participation, including negotiating a delayed last ferry, and they grow close, even staying over at each other’s homes.

Koki Usurai: Her older brother works as Director of the Global Public Relations Strategy Office at the Raiten Kyoto headquarters. He helps rescue her during the confinement incident and negotiates with their grandmother, allowing Mizuki to compete.

Mayumi Usurai: Her grandmother runs the Raiten Group and is treated as an absolute authority in the family. Mizuki calls her by name, reflecting their antagonistic relationship and long-standing neglect.

Parents: They are unable to oppose Mayumi and are nearly estranged from Mizuki. Their compliance with family “rules” deepened Mizuki’s rebellion.

Aoi: An elderly house servant in the Usurai household. In the anime, Aoi temporarily held Mizuki’s smartphone during her confinement.

Azumi Ishikari: A former Naruno Middle School senior and morality committee chair who noticed Mizuki’s voice. She tried to recruit Mizuki to the broadcasting club before moving to Hokkaido and attending Snow Cape High School, later reuniting in Tokyo at the N-Con finals.

Tosei: A ferry operator whom Mizuki persuades to delay the last ferry, enabling Hana’s participation. He illustrates Mizuki’s ability to negotiate with adults.

Pokoko Potanpoko: A prominent rival in Kyoto’s reading division. Mizuki won first place over her at the Kyoto tournament.

She won first place in the Kyoto reading division and advanced to the national tournament again. She is widely discussed among strong national competitors for her rapid growth.

Voice: Yoko Hikasa in the Volume 1 commemorative PV and Miyuri Shimabukuro in the TV anime. She is frequently referred to as the broadcasting club president.

Tags associated with her include “Flower and Asura senior” and “victim of toxic parents.” A playful note in the source reads: “She’s delinquent...” (by Potekichi).

“Soiled with Sadness.” This is the poem she performed to confront her grandmother, channeling her grief and defiance through reading.

“She’s delinquent...” A meta remark from the source highlighting her rebellious past.

Early High School and Voice Talent

She enters high school and discovers competitive reading, quickly gaining recognition thanks to her natural voice. Despite starting late, her rapid rise draws attention from elite readers nationwide.

Recruiting Hana Haruyama

While searching for club content on Junari Island, she meets Hana Haruyama running a casual reading event. Struck by Hana’s overwhelming “reading” talent, she invites Hana to join the Sumomo Hill High School Broadcasting Club.

The Ferry Arrangement

To make Hana’s participation possible, she negotiates with Tosei, the ferry operator, to delay the final ferry. This showcases her resolve and adult-level negotiation skills.

Family Confinement and Rescue

Her brother Koki’s wedding date overlaps with the Kyoto N-Con qualifiers. When Mizuki returns home to declare she will prioritize the competition, her grandmother Mayumi confines her.

Hana connects with Koki via the wedding invitation and, with the broadcasting club’s help, goes to the Usurai home. Mizuki confronts Mayumi with a reading of “Soiled with Sadness,” making her feelings heard.

Koki then speaks with Mayumi, and after tense dialogue, Mizuki is allowed to compete in the Kyoto qualifiers. This event marks the first real step toward repairing Mizuki’s bond with Koki.

Kyoto Tournament Victory and Toward Nationals

She competes in the Kyoto reading division, taking first place over Pokoko Potanpoko. She secures a spot at the national tournament for the second consecutive year.

Reunions and Competitive Circle

In Tokyo at the N-Con finals, she reunites with Azumi Ishikari, who once tried to recruit her in middle school. Their meeting symbolizes how far Mizuki’s reading journey has carried her.
