Movie
Description
Rei Wakana, performing as LAYER, is a third-year student in Geijutsu Academy's Musical Department. As the vocalist and bassist for RAISE A SUILEN, she possesses fair skin, dark-brown hair to her upper back, and striking lightning blue eyes. Standing at 172 cm, she is the tallest main character across all bands. Geijutsu Academy's fine arts policy exempts her from wearing a school uniform. Her signature style features a white wide-neckline shirt, slightly torn jeans, a black sleeveless jacket, silver necklaces, leather bracelets, studded belts with chains, and black ankle boots.

Rei projects a calm and mature demeanor, often leading others to mistake her for an adult, such as when offered alcohol at movie theaters or on flights before her age is corrected. Despite this composure, she maintains emotional distance, withholding opinions or concealing personal struggles like overworking to master demanding bass parts. Her professional experience includes part-time singing jobs and bass support for established artists. Rei possesses a naturally deep singing voice, which caused childhood shyness due to feeling she "didn't sound like a kid." Her childhood friend Tae Hanazono encouraged her to embrace it, helping her overcome this complex.

Her development focuses on gradually opening up through band interactions. Initially reluctant to burden others, she learns to accept help, like when bandmates intervene after she exhausts herself during rehearsals. Rei finds solace in bathing, cooking, and hot milk with honey, while disliking bitter coffee and sea cucumbers. Her stage name LAYER derives from "Reiya" (レイヤ), the Japanese spelling of Rei. Her birth name reflects musical harmony: "Wa" (和) meaning peace/harmony and "Kana" (奏) meaning "to play music"; "Rei" (レイ) is written in katakana with no inherent meaning.

Key details include her use of a five-string bass variant, her status as the only main character never depicted in a school uniform, and her childhood connection to Tae, including their shared attendance at music school with Arisa Ichigaya. Rei's personal growth is shown through her increasing willingness to share vulnerabilities and collaborate, moving from self-reliance to trusting her bandmates' support.
